Ten Themes of Biology
Goal: Describe the 10 themes that can help you organize what you learn
about biology.
![Page 12: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/12.jpg)
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
![Page 13: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/13.jpg)
Ten Unifying Themes of Biology
1. Biological Systems – cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere
![Page 14: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/14.jpg)
2. The Cellular Basis of Life – the cell is the smallest unit of life. All living things are made of cells.
![Page 15: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/15.jpg)
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)
![Page 16: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/16.jpg)
4. Reproduction and Inheritance – you inherit similarities from your parents (Example: if nothing else your parents are human and so are you!)
![Page 17: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/17.jpg)
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)
![Page 18: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/18.jpg)
Question of the Day
• Without looking at your notes from yesterday, try to name the five themes of life we discussed yesterday.
![Page 19: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/19.jpg)
Ten Themes of Biology
Goal: Describe the 10 themes that can help you organize what you learn
about biology.
![Page 20: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/20.jpg)
6.Energy and Life – Every organism needs energy to live.
What happens when an organism runs out of energy?
![Page 21: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/21.jpg)
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.
![Page 22: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/22.jpg)
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.
![Page 23: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/23.jpg)
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
![Page 24: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/24.jpg)
10. Scientific Inquiry – Asking questions, using observations or experiments to find possible answers
![Page 25: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/25.jpg)
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.
![Page 26: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/26.jpg)

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.
![Page 31: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/31.jpg)
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
![Page 32: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/32.jpg)
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.

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

![Page 52: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/52.jpg)

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?
![Page 55: WELCOME](https://reader036.vdocuments.us/reader036/viewer/2022070502/56813fec550346895daaea48/html5/thumbnails/55.jpg)
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
Low Power High Power
