3. The Science behind, includes three subsections Based onobservations (prompts to answer based on the observationsmade during the activity proper), How does it work? (the
scientific explanation behind the observation considered as most
striking), and The essential concept is(prompts that will finallygive focus to the most essential concept to be discovered and
learned from the activity).
4. Learning MixBlotter, is a writing template to be filled out withresponses to all activity prompts given.

Whats the Challenge?With the use of red cabbage extract, you will
test the pH of each of five mixtures in liquid
form to determine if it is acidic or basic.
What you need
o red cabbage extracto plastic droppero 5 unknown mixtures (each contained in a
plastic cup)
Hands-on
1. Add five drops of the red cabbageextract onto each of the five plastic cupscontaining a mystery mixture. Swirl the
content of the plastic cup thoroughly.2. Determine the pH of the resulting mixture
by referring to the figure below.
3. With the use of your sense of smell, identifyeach of the five mystery mixtures. (HINT:
Each mixture is a common or familiar
household product mixed with water.)
Based on observations
1. Which of the five mixturesis/are acidic? Basic?
2. What is the identity of eachmixture?
3. How many phase(s) doeseach mixture show?
Identify the phase(s).
4. Each mixture is composedof a common household
product mixed with water.
Which between the
household product and
water is the solute and
which one is the solvent?
(NOTE:Solute is the part of
mixture which is smaller in
amount; solvent is the partin bigger amount.)
How does it work?
The essential concept
is
Each of the five mystery mixture
classified as a solution. Based
your responses to prompts 3 and
describe in one sentence whasolution is.
The Sciencebehind
Red cabbage contains a pigment molecule called
(an anthocyanin).
Very acidic solutions will turn anthocyanin red in
Neutral solutions result in a purplish color. Basic s
appear in greenish-yellow. Therefore, it is poss
determine the pH of a solution based on the color

Whats the Challenge?
You will make a liquid mixture of cornstarch
and water turn into solid by tapping on it. Themixture is known as an Oobleck!
What you need
o corn starch (about cup)o water (about cup)o food coloringo mixing bowlo newspapero spoono plastic cupHands-on
1. Place a sheet of newspaper flat on thefloor; put the mixing bowl in the middle ofthe newspaper.
2. Add cup of dry cornstarch to the bowl;then, add about 1/8 cup (2 tablespoons)of water (added with food coloring) to the
corn starch and stir slowly. (Add water
slowly to the mixture, with stirring, until allof the powder is wet.)
3. Continue to add water until thecornstarch acts like a liquid when you stir
it slowly. When you tap on the liquid with
your finger, it shouldn't splash, but ratherwill become hard.
(NOTE: If your mixture is too liquid, addmore cornstarch. Your goal is to create a
mixture that feels like a stiff liquid when youstir itslowly, but feels like a solid when you
tap on it with your finger or with a spoon.)
Based on observations
1. What happens to the
Oobleck when you
rub it between your
palms? When youyou stop rubbing?
2. After leaving the
cornstarch mixture in
a plastic cup for
some time, what can
be seen at the
bottom of the plastic
cup?
How does it work?
The essential concept
is
Scientists call Oobleck a non-Newto
fluid (just like ketchup and quicksand).
In an Oobleck, the cornstarch is suspen
in the water (instead of compl
dissolving, just like sugar or salt).
Applying a force to the Oobleck sque
the water out from between the cornst
bits. Pulling or pouring the Oobleck, on
other hand, gently lets the water
between the cornstarch bits.
The Sciencebehind
An Oobleck is classified as
suspension rather than a solut
Based on your response to promp
what then is a suspension?

Whats the Challenge?
You will create a lava lamp by making
colored blobs floatin a mixture!
What you need
o 1-liter clear soda bottleo cup watero vegetable oilo fizzing tablets (ex. Alka Seltzer)o food coloringo funnelo flashlightHands-on
1. Pour the water into the bottle.2. Using a funnel, add the vegetable oil into
the bottle until it is almost full.3. Add ten drops of food coloring into the
bottle.4. Break a seltzer tablet in half and drop the
half tablet into the bottle. Watch it sink to
the bottom and let the blobbygreatnessbegin!
5. To keep the effect going, just add anothertablet piece. (NOTE:For a true lava lamp
effect, shine a flashlight through the
bottom of the bottle.)
Based on observations
1. What happens to the
vegetable oil when it is
added to water?
2. To which does thefood coloring mix, with
water or with oil?
3. What are the colored
blobs made of?
4. On which part of the
mixture do the colored
blobs float as the
seltzer tablet is added?
How does it work?
The essential concept
is
The Sciencebehind
Water and oil do not mix (they are said toimmiscible liquids) so when we add oil to
water, the water sinks to the bottom of
bottle, while the oil settles at the top.
The food coloring mixes with the water
does NOT with the oil.
The Alka-Seltzer tablet reacts with the wa
making bubbles of carbon dioxide gas. Th
bubbles attach themselves to the colo
water making them float - hence the l
lampeffect.
The mixture consisting of the colored wa
blobs floating on oil in the lava lamp
classified as an emulsion.
What is the similarity and what is
difference between an emulsion and
suspension? (HINT:Consider the phases
the individual components of the mixture

Whats the Challenge?
Satisfy your sweet tooth by making a
delectable frozen delight ice cream!
What you need
(per cup serving):
o 50 mL ( cup) milko 50 mL ( cup) whipping creamo 25 mL (5 tsp) sugaro 0.5 mL (1/8 tsp) vanilla or vanilla flavoringso 100-175 mL ( cup) salto 500 mL (2 cups) ice cubeso one 1-L (1 quart) zip-top bago one 4-L (1 gallon) zip-top bago spoonHands-on
1. Place the pre-measured sugar, milk,whipping cream and vanilla into the
smaller zip-top bag; seal the bag securely.2. Put the ice cubes into the larger zip-top
bag. Add salt to the bag of ice.3. Place the sealed smaller bag inside the
larger bag of ice and salt; seal the larger
bag securely.
4. Gently rock the larger bag from side toside. (Caution: Hold the bag by the top
seal as the bag gets too cold throughcontinuous shaking.)
5. Shake and rock the bag for 5-10 minutesor until the content of the smaller bag hassolidified into ice cream.
Based on observations
1. Describe the
consistency of the
ice cream.
2. How many phase(s)of matter is/are seen
in the ice cream?
How does it work?
The essential concept
is
The Sciencebehind
Milk with dissolved sugar and whipping c
freezes at much colder temperature than
water (0C).
When salt is added to ice, it dissolves in the
on the surface of the ice cubes. Salty w
freezes at a much lower temperature than
water.
Thus, the salt and ice mixture gets much cold
a temperature lower than zero degree C
enough to turn the mixture into ice cream.
Ice cream is both an emulsion and a fo
