welcome

WELCOMEBiology with Ms. Jacobs

Goals for the Day1. Get to know each other

2. Make & understand classroom expectations/rules

3. Get excited about Biology!

Question of the Day• Each day in class I will put up a question of

the day. • Students will be responsible for writing the

question & their best answer.• After each student has answered the question

on their own we will discuss it as a class• QODs will be collected before each test for

points!!!

Classroom Rule(s)1. Have Respect.

– For yourself– For your classmates– For the classroom– For the teacher

2. Follow all RHS handbook rules

Question of the Day• What does respect look like to you in the

classroom?

Information Cards & Goals• Full name• Interests• Activities you are in or are planning to

tryout for (Spring & Fall)• 3 Goals for yourself this year

– What do you want to do, accomplish, or learn?• What else should I know about you?

Science Autobiography1. What has been your general experience of

science inside or outside of school?– Did you enjoy it? What did you enjoy?– Did you not enjoy it? Why didn’t you enjoy it?

2. What about science/biology interests you?3. What specifically do you already know/have

you talked about the scientific method?4. What is your experience using microscopes

and how comfortable are you with the parts & rules of proper use?

Lets start learning names!

Question of the DayPlease write this down in your notebook, and do your best to answer it!

What do you have in common with the avocado

plant in our room?

Ten Themes of Biology

Goal: Describe the 10 themes that can help you organize what you learn

about biology.

Ten Themes of Biology

1.Biological Systems

Cell s Tissue Organ

Organ System Organism

Tissues working together

Cells working together

Organs working together

A living thing

Ten Unifying Themes of Biology

1. Biological Systems – cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere

2. The Cellular Basis of Life – the cell is the smallest unit of life. All living things are made of cells.

3. Form and Function – the shape of things help that organism to do what it does

(Example: the anteater’s long snout enables it to squeeze in tight places to get food)

4. Reproduction and Inheritance – you inherit similarities from your parents (Example: if nothing else your parents are human and so are you!)

5. Interaction with the Environment – every organism gives off stuff to the environment and every organism takes stuff from the environment (Example: you give off heat and take in food)

Question of the Day

• Without looking at your notes from yesterday, try to name the five themes of life we discussed yesterday.

Ten Themes of Biology

Goal: Describe the 10 themes that can help you organize what you learn

about biology.

6.Energy and Life – Every organism needs energy to live.

What happens when an organism runs out of energy?

7. Regulation and Homeostasis

Homeostasis – the maintenance of a stable internal conditions in spite of changes in the external environment.

Example: Even though our surrounding temperature is constantly changing our internal temperature (body temperature) stays the same.

8. Adaptation and Evolution – Adaptation is an inherited trait that helps the organism’s ability to survive and reproduce. Evolution is just a change over time.

9. Biology and Society – • How does our society affect life

and how does our understanding of biology affect our society?

• Cloning, Stem cell research, environmental issues, hunting, medicine, genetically modified crops

10. Scientific Inquiry – Asking questions, using observations or experiments to find possible answers

10 Themes Practice• Describe or relate ALL 10 themes of Biology

in relation to a living thing.

• Example: Describe how the form of the organism might fight a particular function or help it in its environment.

• For the 10th theme (Scientific inquiry) come up with at least 2 questions about your organism.

Ten Themes of Biology

Goal: Describe the 10 themes that can help you organize what you learn about

biology.

•How do you feel about your progress on our goal today? What questions do you still have?

Question of the Day

• Name the 5 steps of the scientific method.

Goals for the day

1. Become more familiar with the 5 steps of the scientific method as described in our book.

2. Learn the function of each part of a microscope.

Scientific Method

• Observation• Question• Hypothesis• Prediction• Test/Experiment

Scientific Method• Observation

– The students in the class do not know each others names.

• Question– How could I help them to learn each others names?

• Hypothesis– Playing games involving their names will help

them become familiar with each others names.

Scientific Method• Hypothesis

– Playing games involving their names will help them become familiar with each others names.

• Prediction– IF we play enough games with the names of

their classmates THEN students will know each others names.

• Test/Experiment– Play the games

Scientific method activity• In your groups look at the question you had about

your insect.

• Go through each step of the scientific method for your question (Make sure you number them!) and write it down.

• For the test step develop and describe an experiment that you think could test your hypothesis!

• Turn in to the folder when finished.

Goal for the day

1. Learn the function of each part of a microscope.

Question of the Day• WITHOUT looking at your notes: Name the 10

themes of Biology

• F• I• B• E• R

• C• R• A• B• S

Goal for the day

1. Learn the function of each part of a microscope.

2. Become comfortable using and focusing microscopes.(While getting to know a little more about the microscopic world around us!)

Practice USING Microscopes1. After you finish your microscope activity online

get a microscope from the cart. 2. Get a prepared slide from the front lab bench,

and focus it first on LOW power.3. Draw what you find and label the Total

magnification4. Also draw and label the specimen under medium

power.5. Repeat with a wet mount slide

(see Ms. Jacobs for directions)

Question of the Day

• How do you calculate the total magnification of a microscope?

• Hint: What two things do you have to multiply together?

Microbiology practice1. Get a prepared slide from the front lab bench,

and focus it first on LOW power.2. Draw what you find and label the Total

magnification3. Also draw and label the specimen under

medium power.4. Repeat with a wet mount slide on low and high

power, draw at least 5 different living organisms! (see Ms. Jacobs for instructions on making your first wet mount slide)

Microscope activity• Get your assigned computer from the computer cart.

(work in pairs)

• Go through activity according to directions

• Make sure you complete each step before moving on!

• We will also be working on this tomorrow.

Goal for the day

1. Learn how to write a brief lab report

2. Practice using the steps of the scientific method.

Question of the Day

• What two groups do you have in an experiment? How are they different?

• Hint: Think back to Friday when we talked about the scientific method, and the miracle grow.

Scientific Method ActivityLab Report

• Observation• Question• Hypothesis• Prediction• Experiment

Scientific Method ActivityLab Report

• Procedure– Explain your test so that another person could do

the exact same thing• Results/Data

– This section displays your results and data. You should include at LEAST one graph or chart

• Conclusions– What did you experiment show? Use your data to

support your conclusions!

Goal for the day

1. Review parts, function, and use of microscopes.

2. ASK QUESTIONS you still have over the scientific method and the use of microscopes!

Question of the Day

• What is the difference between a prediction and a hypothesis?

Calculating Magnification

To calculate the total magnification of a microscope you multiply the magnification of the eyepiece by the magnification of the objective.Example: If a microscope has an eyepiece magnification of 20x and an objective magnification of 50x the total magnification of that microscope is 1000x.If a microscope has an eyepiece magnification of 10x and an objective magnification of 25x the total magnification of that microscope is __________.

250x

Microscope Movement

When you move a slide on a microscope to the left, the specimen

appears to move toward the right when viewed under the microscope.

If you move the specimen up it will appear to move down under the

microscope. All movements under the microscope

are opposite. Why does the opposite movement

happen?

Microscope Field of ViewWhen you switch from low power to high power a

couple of things happen. 1. Your object will be more magnified2. Your object will need to be focused (use the

fine adjustment knob only!)3. Your field of view will be smaller
