Thermal Energy -- Third Grade Digital Kit Written By Rachael Freed
He who made the Pleiades and Orion, who turns midnight
into dawn and darkens day into night, who calls for the
waters of the sea and pours them out over the face of the
land-- the LORD is his name. (Amos 5:8)

Goals of the British Columbia Education Plan
Our curriculum team is excited to bring you a summarized version of the new BCEd
plan core goals (competencies), strategies and content. As we develop the kits we will
be personalizing the content to suit your students’ need and interests. Big ideas and
concepts will be the focus as well as curricular threads, inquiry learning (discovering
how to ask the right questions based on who, how and why things occur, as opposed to
what things occur), technology integration, and collaboration. First Peoples content will
include the natural history/culture of our province and encourage our God given
diversity. The kits are designed to help you gain a greater understanding of the
following:
Biblical Worldview:
We believe that every child in our school needs to hear the voice of God interwoven into
their entire curriculum. Therefore we will be striving to make sure that this goal is an
overarching strategy.
Communication Competency:
Involves imparting and exchanging information, experiences and ideas, to explore the
world around them, and to understand and effectively engage in the use of digital
media.
Thinking Competency:
Encompasses the knowledge, skills and processes we associate with intellectual
development. It is through their competency as thinkers that students take subject-
specific concepts (ideas that interest them) and content, (topics that need to be covered
to increase knowledge, and transform them into a new understanding to increase
knowledge), and transform them into a new understanding. This includes specific
thinking skills as well as how students are allowed to learn, make mistakes and grow
from failure. Encompassed in this thinking is the ability to feel safe and comfortable so
that students can explore their surroundings.
RV 11/09/2016 NS
Creative Thinking Competency:
Involves the ability to generate new ideas and concepts that have value to the individual
or others, and then develop these ideas and concepts from thought to reality. It requires
a curiosity and a wondering reflection about God’s creation, with a desire to make
something new and different from what they have read, seen or observed.
Critical Thinking Competency:
Encompasses a set of abilities that students use to examine their own thinking and that
of others, and process information they receive through observation, experience, and
various forms of communication.
Social Responsibility:
Involves the ability and disposition to consider the interdependence of people with each
other and the natural environment; to contribute positively to one’s family, community,
society, and the environment; to resolve problems peacefully; to empathize with others
and appreciate their perspectives; and to create and maintain healthy relationships.
Personal and Social Competency:
Is the set of abilities that relate to students' identity in the world, both as individuals and
as members of their community and society.

Learning Strategies
In response to the goals set out by the BC Ministry of Education, HCOS has made it a
priority to make use of the following learning strategies throughout our unit studies and
courses.
Biblical Worldview: Biblical worldview refers to the framework of ideas and beliefs
through which a Christian individual, group or culture interprets the world and interacts
with it. Individuals with a biblical worldview believe their primary reason for existence is
to love and serve God. A Biblical worldview is based on the infallible Word of God.
When you believe the Bible is true, then you allow it to be the foundation of your life. We
believe that every student at HCOS needs to develop a worldview based on their
Biblical thinking and beliefs.
Inquiry-Based Learning/Mindset: Students with an inquiry mindset have a God-given
curiosity; a desire to dream big, constantly challenge themselves, and a desire to
research more for increased understanding and clarity. Students who actively inquire
will scan their environments, generate good questions, try new approaches, observe
and collect evidence, synthesize the information, draw conclusions, and generate new
questions from their research.
Maker Education: The Maker Education Initiative’s mission is to create more
opportunities for all young people to develop confidence, creativity, and interest in
science, technology, engineering, math, art, and learning as a whole through making.
This may be through STEAM – science, technology, engineering, art and mathematics.
The “maker mindset” includes learning to use your imagination to make connections,
use intuition, persist through difficult circumstances in learning, collaborate with other
team members and community, and become disciplined learners. Maker education
often involves an interdisciplinary approach, teaching science, math and art together.
Here is an example. To learn more go to this page.
First Peoples Content: First Peoples content has been interwoven into every grade in
the new BCEd plan. Aboriginal content is for all learners of all ages, and includes a
healthy diversity of approaches. From learning about cultural traditions and schooling
injustice, creative ways of storytelling, and good stewardship of land and resources, we
can gather rich learning from the traditions of the people groups indigenous to BC. As
Christians we can draw many similarities from their holistic thinking, and share how our
beliefs and traditions might be similar or different.
RV 11/09/2016 NS
HCOS Subscriptions
HCOS families have access to a wide variety of wonderful subscriptions which can be
used to enhance student learning. Several of these subscriptions are used throughout
the unit. Each year, a document containing the usernames and passwords for each
subscription is sent to families. If you have not received this document please contact
your child’s teacher.
RV 11/09/2016 NS
Big Ideas “Big ideas are statements that are central to one’s understanding in an area of learning.
A big idea is broad and abstract.” (CT) Big ideas represent the overarching theme of
each unit. They contain references to the content and key questions students will be
investigating throughout the unit. Big ideas are often cross-curricular in nature. Similar
themes can be found in many different subject areas within each grade-level.
Science Thermal energy can be produced and transferred.
RV 11/09/2016 NS
Curricular Competencies
“Competency represents the combined skills, processes, behaviours and habits of mind
that learners use to make sense of the world.” (CT)
Science Questioning and Predicting: Cause and effect

How to Use This Kit
The Ministry of Education is in the final stages of overhauling curriculum, learning
strategies, and learning goals for students in the Province of British Columbia. This kit is
designed with those goals in mind. On the next several pages you will discover the
content that serves as the “bulk” of this kit. Rather than being divided by day, the unit
plan uses the key questions detailed on page 8 to breakdown content, activities, and
experiences.
Each key question will have books to read from the HCS Overdrive E-Library, (if you do
not have your client code & pin, please contact Shandra Wiebe at
swiebe@onlineschool.ca), videos to watch, and activities to share with your child. You
will not be required to complete all activities listed under each key question, instead, you
will be able to choose activities which most appeal to you and your child. Each key
question featured in the unit will include recommendations on how many activities to
complete in order to fully address the curriculum content and competencies. Finally,
each activity will have icons (shown on pages 2 and 3) showing which goals of the
BCEd Plan the activity addresses.
***You are encouraged to choose varied activities to ensure all goals are being
addressed. In order to fully meet the goals of this kit, it is important to read 6 or
more of the recommended books, and watch 10-16 videos.***
Reading and discussing/watching and discussing the books and videos listed in this unit
will consistently address the following goals of the BCEd Plan:
It is our hope that our redesigned format will allow for flexibility, individual preference,
and student-centered learning. When selecting activities to complete with your child we
recommend selecting a variety of activities to ensure that you touch on each BCEd Plan
goal throughout the unit. Most activities are designed to address multiple goals.

learn how to create a learning blog for your child. Blogging allows students to publish
writing, post pictures of completed projects, and share information with family, friends,
and teachers in a protected environment. Using a blog can be a wonderful means of
creating a digital portfolio that your child can use throughout their grade-school years.
Initially, your child will need assistance with learning how to use the site and share
information. In time, your child will be able to post their work on their blog without
assistance.
Look-Inside Volcano Project: What do you know about volcanoes? What causes
volcanoes? Where are volcanoes located? What do they look like? Do all volcanoes
look the same? What happens when a volcano erupts? Are they all the same size?
What sort of energy do volcanoes emit? What are underwater volcanoes like? What
other questions do you have about volcanoes? How can you find the answers to these
questions, and the other questions you may have? Watch Volcano from Learn 360.
Then, read more about volcanoes from World Book Kids and/or Explora. Once you have
learned about volcanoes create a look-inside volcano.
For this project you will need a small water bottle, 3" of clear tubing with 7/8" outer
diameter (fits perfectly inside opening of water bottle), 4 feet of smaller clear tubing (we
used 5/16" outer diameter and 3/16" inner diameter, but actual dimensions are not
critical), brown play dough (use 4 times this recipe with about 1/4 cup of instant coffee
replacing the 15 drops of food coloring. This made about 8 cups of dough.), tray to hold
volcano, (we used clear glass pie dish), empty ketchup dispenser with skinny nozzle,
baking soda, vinegar, red food colouring, scissors, single hole punch, funnel, measuring
cup, clear sheet of thin plastic (the blogger suggests using a thermal laminated pouch,
laminated with nothing inside), a sharpie or other marker, dish soap, and a chopstick.
Photos of the instructions here, instructions from 123 Homeschool 4 Me.
Step One: “Insert the smaller tubes into your water bottle. You want to end up with
two 6" tubes directly across from each other on the left and right of the bottle (the
secondary vents) and one long 3 foot tube between them at the back (playdough side)
of the bottle (the tube for inserting vinegar). To insert these tubes, first trace around the
tube at these 3 locations near the opening of the water bottle. Then use the single hole
RV 11/09/2016 NS
punch to cut out the interior of your drawn circles. You may need to punch 3 or 4 times
for each hole. Then insert the tubes as shown.”
Step Two: “Next, cover half of the magma chamber (water bottle), secondary
vents, and vinegar tube with brown play dough. Add the 3" larger tube to the
opening of the water bottle to form the central vent or throat of the volcano and cover
that with brown play dough as well, as shown. Make sure you form a crater near the top.
When you are done, you can cut off the excess length of the secondary vents. (Note:
While you are doing this, you may want to skip ahead to Step 4 and fill your water bottle
with "magma".”
Step Three: “Next use your marker to mark the edges of your crater on a thin
piece of clear plastic. Use your lines as a guide to cut out a small piece of plastic
which will contain the escaping lava and force it to go down the volcano side and not the
cutaway side of your model. Attach the plastic to the volcano using playdough.”
Step Four: Create magma! “Using the funnel, I added 1/4 cup of water with 20 drops of
red food coloring. To that, I added about 1/2 cup of baking soda to the water bottle. The
baking soda quickly settled to the bottom of the bottle. You could likely try using less
water and a chopstick to stir up the mixture in order to make it look like more uniform
"magma," but I just left it as is.”
Step Five: “To make the vinegar solution, simply fill your ketchup bottle most of
the way with vinegar and add some red food coloring. You could also add a little
dish soap to make the lava foamier. I used about 20 drops of food coloring and a
tablespoon of dish soap.”
Step Six: Now you are ready to start your volcanic eruption! “Our "lava" was fully
contained, but unless you're braver than me, I might recommend taking your volcano
outside. To start the lava flow, simply insert your ketchup bottle tip into the long tube
and squeeze the vinegar into volcano.” Did it work? What happened? Record your
observations and share on your blog (see above – Blogging).
Geyser Experiment: What is a geyser? Have you heard of the geyser “Old Faithful”?
Read about geysers and “Old Faithful” from World Book Kids. Then, conduct this simple
experiment to create your own geyser. For this experiment you will need a pot of water,
a funnel and some tin foil. Fill the pot full of water and place the funnel in the pot upside
down (you may prefer to use a metal funnel) with the tube/spout part sticking up out of
the water. Cover the pot with the tin foil, making a hole for the spout of the funnel to be
open and release steam. Turn the pot on high and let it boil. Once it starts boiling,
RV 11/09/2016 NS
steam will escape and then the water will spout out of the tube just like a geyser! Be
sure to stand at a safe distance. This experiment requires adult support!
Volcano Art: Have fun conducting a science experiment and creating art at the same
time! For this project you will need canvas or good quality art paper, baking soda, water,
vinegar, and food colouring. Use a small amount of water to create baking soda paste,
paint a layer of baking soda paste on your paper or canvas. Then, add drops of food
colouring. Finally, spray with vinegar and see what happens! Brush off the remaining
baking soda once the picture is dry. To see an example, look here.
Thermal Reaction Glow Stick Experiment: (Safety: this experiment uses hot water,
adult support will be needed. Avoid getting chemicals from the inside of the glow stick
on skin, eyes, or clothing).
For this experiment you will need hot water (electric kettle hot), 2 cups, water with ice,
paper towels, and a camera or paper for documenting your experiment.
Take two cups and 2-3 glow sticks of the same colour. What do you know about glow
sticks? How do they work? What do you notice about the liquid inside of the glowstick?
Bend the glowstick to break the ampule inside.
Pour very hot water (close to boiling) into one cup and the ice water into the second
cup. Place one stick in the hot water and one in the cold water. Turn off the lights to
observe. What do you see? How do the glow sticks react to the two different water
temperatures? What happens if you switch the sticks from the two cups? Do different
coloured glow sticks react differently? How long will a glow stick stay lit in a freezer? In
hot water? What other ways could you experiment with the glow sticks? How and why
does this experiment work?
“Light sticks are examples of luminescence and fluorescence. The chemical
reaction that starts when you break the glass ampule in the lightstick releases enough
energy to cause the electrons in the fluorescent dye to get excited. Immediately these
electrons drop back down to their normal state and give off energy in the form of light. In
this experiment you are using the thermal energy of the hot and cold water to change
how quickly the reaction happens.” Visit here to see photographs of the experiment.

however, if you cannot find 12% hydrogen peroxide, regular drug store hydrogen
peroxide will work, just use a smaller bottle to ensure the reaction is equally impressive.

Activities (Select 3-6) :
Solar Balloons Experiment: The sun provides us with a lot of energy in the form of
heat. See the power of solar energy by conducting this simple experiment. You will
need two large, empty pop bottles, two balloons, and black and white paint. Paint both
bottles, one with the white paint and one with the black paint--you may need more than
one coat of paint. Then, attach a balloon to the top of each bottle so that it covers the
entire mouth of the bottle and stretches down below the ridges where the cap screws
on. Place your bottles outside in direct sunlight. What happens? Consider the following
questions:
● Did one bottle get warmer inside? Why?
● What did the air inside the black bottle do?
● Why does the balloon on the black bottle get bigger?
● After conducting this experiment, what do you think happens when you wear
black clothes in the summer?
● Could you use this method to heat your house? How?
Conduction, Convection, and Radiation: Popcorn Lesson (Three Methods of
Heating): Conduction, convection, and radiation are three ways of heating the
atmosphere (and everything within the atmosphere). It can be tricky to remember the
differences between the three forms of heating. Experiment with conduction,
convection, and radiation by making popcorn!
RV 11/09/2016 NS
● 1. Put oil in the bottom of a pan. Cover the bottom of the pan with popcorn
kernels. Place the pan on the stove and turn on the burner to medium heat.
Cover the pan with a lid. Periodically shake the pan so the kernels move around
in the oil. (Conduction: The heat is transferred by direct contact from the
pan, to the oil, to the kernels of popcorn.)
● 2. Obtain a popcorn popper. Place the popcorn kernels in the popper. Plug
in/turn on the popper. Hot air will transfer heat to the kernels, making them
expand and pop. (Convection: The hot air transfers the heat to the cooler
kernels, and when enough hot air heats the kernels, they pop.)
● 3. Microwave a bag of microwave popcorn. Each of these methods of cooking
popcorn is really an example of the three ways heat can be transferred.
(Radiation: The kernels are heated by the radiation in the microwave, and
the kernels heat up, giving off more heat to the kernels surrounding it and
making it “doubly warm.”)
Heat Conduction: This experiment demonstrates how water can conduct and absorb
heat. You will need a lit candle, water and balloons. Begin by blowing up a balloon. Hold
it over a lit candle, what happens (if your child is sensitive to noise, warn them that the
balloon will pop)? What happened? The lit candle weakened the balloon, melted it, and
caused it to pop. Now take another balloon and fill it halfway with water. What do you
think will happen this time? Try touching the balloon to the candle, what happens? Why
do you think the balloon isn’t popping? (The water in the balloon is absorbing the heat
from the candle--see here for photos of the experiment).
Build a Solar Oven: Cook s'mores using your own solar oven. For this exciting
experiment you will need a pizza box, aluminum foil, plastic wrap, tape, scissors, a ruler,
a paper plate, and supplies for s’mores. “Cut a flap in the top of the pizza box leaving a
2″ border on the sides and front. Wrap the bottom side of the flap and the interior of the
pizza box with aluminum foil – shiny side out – and tape in place. Cover the opening
created by the flap with plastic wrap and tape into place. Place marshmallows to be
cooked on a paper plate inside the solar oven. Prop the flap open with a ruler in
position to reflect the sun into the oven. Let the sun bake the marshmallows. Depending
on the time of day, heat and other variables, it may take up to an hour. Be careful
removing food {it will be hot!} and then add crackers and chocolate for a yummy
s’more.” How does this work? According to the Museum of Science and Industry: “The
sun’s light rays are collected by the foil flap and concentrated inside the box. The rays
RV 11/09/2016 NS
are transformed into thermal energy that slowly raises the temperature inside the box,
causing the food to cook.”
Solar Cooker with BrainPop Jr.: Watch Heat from BrainPop Jr. Then, follow their
instructions to create your own solar cooker.
Cook an Egg on the Sidewalk: On a hot, sunny day, try cooking an egg on the
sidewalk. If you want to up the heat factor, place tin foil between the sidewalk and the
egg.
Why Do We Need Sunscreen? An Experiment: For this interesting experiment you
will need cream sunscreen and black construction paper. Fold your construction paper
in half. Put a very small amount of sunscreen on one side of the paper and spread it
(thin and even) so it fills one full half of the paper. Place the paper outside in direct
sunlight. After five+ hours you will be able to see that the sunscreen has kept half of the
paper dark black, while the other half has faded. What happens to our skin when we are
in the sun? What harm can the sun cause? Why is the sun very important to life on
earth? How can we protect ourselves from the harmful effects of the sun while still
enjoying the positive effects of the sun?
Solar Motor/Solar Energy Tower: Follow the instructions from the National Research
Council of Canada to create a solar motor. For this exciting activity you will need three
tin cans, a can opener, masking tape, thumbtacks or straight pins with heads, one sheet
of white paper or aluminum foil 15cm square, scissors, wire, two bricks, wooden blocks
or stacks of books. After you conduct the experiment, consider the following questions:
● What would happen if the tower was not on the books?
● Would a paper tower work in place of cans?
● Would pinwheels made of different materials, or in different sizes spin faster?
● What if the tower was painted black?
● Could enough power be generated by the spinning pinwheel to turn a generator?

Make a Solar Still: Water Desalination Experiment: For this fascinating experiment
you will need a glass container, ½ teaspoon of salt, 1 cup of warm water, a second
(smaller) glass container shorter than the edge of the first container when it sits inside,
one or two rocks or several glass beads, plastic wrap that will secure tightly around the
containers, and a spoon. Begin by pouring water into the larger container, add the salt
and stir. Place the smaller container in the center. Then, tightly wrap the containers in
plastic wrap. The wrap should not be touching the smaller container. Add the rocks or
glass beads to the centre of the container. Let it sit for two hours or more in the sun.
The longer it sits the more water will collect in the smaller container. Remove the plastic
wrap and taste the water in both containers. Why did this work? What has happened?
What do you observe about the containers and the materials you used to conduct the
experiment? What role did the sun/solar energy play in transforming the water? How
could desalination harm sea creatures?
Heat Energy Experiment: For this experiment you will need two clear glasses, hot
water, cold water, and food colouring. Pour hot water into one glass and cold water into
the other. Let the glasses sit untouched for 2 minutes. With a dropper, carefully place
one drop of food colouring into each glass. Do not touch or move the glasses, simply
observe what happens to the food colouring in each glass. What do you see? What
happens to the food colouring in the cold water? What happens to the food colouring in
the hot water? Why is there a difference? (Heat energy is the energy of vibrating
molecules, the faster the molecules vibrate, the hotter the water. Because the
molecules in the hot water are moving more quickly the food colouring moves about the
glass faster).
Expanding Balloon: Follow the instructions from Steve Spangler Science to use heat
to expand a balloon! If you don’t have a hot plate, you can place your bottle in a pot
filled with water.
Insulator Designer: Which insulator will keep a cup or jar of hot water hottest for the
longest amount of time? For this experiment you will need 4-5 mugs or glasses, hot
water, a thermometer, and insulating material (fabric, bubble wrap, paper, foil, anything
RV 11/09/2016 NS
else you would like to try). Wrap your glasses in the insulated material. Then, place
them on a table or counter. Have an adult pour very hot water into each glass. Use a
thermometer to take the temperature of each glass, record it on a piece of paper. Take
the temperature again at 5-10 minutes intervals. Which glass cools down first? Which
glass stays hot for the greatest length of time? Which insulator works best? Why do you
think this is? What are situations in which it is useful to have insulators?
Technology Time: Have fun exploring Energy Quest!

RightNow Media. Discuss what happens in the story. Read the Shadrach, Meshach and
Abednego story from your favourite Bible. How is the Veggie Tales version of the story
different from the version shared in the Bible? How are they the same? What do you
know about heat energy? What are examples of heat energy in the story? How do they
make the furnace hotter? What should have happened to Shadrach, Meshach, and
Abednego with that much heat? What are some other things that give off as much heat
as the furnace in the story? What does this story tell us about the power of God? Have
you ever been in a situation where you have had to stand-up for what you believed? Is it
always easy to do the right thing? Who do we need to rely on in difficult situations?
What are some other Bible stories in which we learn to trust in God? Use paint,
construction paper, tissue paper, glue, and other materials to create artwork showing
the story of Shadrach, Meshach, and Abednego. Share your artwork with a friend or
family member and explain to them what we can learn from the story.
Technology Time: Have fun exploring the Kids Energy Zone.
Convert Radiant Energy to Thermal Energy: (Safety Note: this experiment involves
creating fire, adult supervision is mandatory). Conduct this experiment and try
converting energy! Radiant energy is energy that is transmitted in a wave motion--
picture waves in your mind, can you use your hand to show how a wave moves? Light
is a form of energy that travels in waves--it is radiant energy. Thermal energy is energy
in the form of heat. Create thermal energy by rubbing your hands together; you are

using friction to create heat. For this experiment you will need a pie plate or cake pan, a
small piece of white paper, a magnifying glass, and a glass of hot water. You are going
to use the magnifying glass to concentrate the radiant energy of the sun and convert it
to thermal energy. If you can heat the paper until it burns than the conversion has been
successful.
Procedure: Tear off a small piece of paper and place it in the centre of the pie plate.
You need to be in an area where you have direct sunlight. Use the magnifying glass to
focus the sunlight into a tiny circle on the paper. Once the light is focused it should not
take very long for the paper to begin to burn. Consider trying a scrap of black to see if it
burns faster or slower.
To learn more about thermal energy and thermal energy transfer visit PBS Learning
Media and launch the interactive presentation.
Conductors Versus Insulators Marshmallow Experiment: Stick mini marshmallows
on a wooden spoon, and more mini marshmallows on a metal spoon. Place both
spoons upright in a pot of boiling water. Which marshmallows melt the fastest? Why do
you think this is? Which material is a conductor? Which material is an insulator? Use
Explora to find the definitions of insulator and conductor.
