9. Benchmark Study Guide Answers 1) What are the steps of a scientific investigation? (Scientific Method) and why do we follow these steps? 1. Ask a question, 2. form a hypothesis, 3. test hypothesis, 4. analyze results, 5. draw conclusions, 6. communicate results. 2) What is a controlled experiment? An experiment that compares the results from a control group with the results from one or more experimental groups. 3) How is a graph used in the scientific method? To analyze data. 4) What is a limitation of a physical model? It can not grow and change like the real thing.

10. Benchmark Study Guide Answers 5) Define the following Mathematical model – made of mathematical equations and data. Conceptual model – systems of ideas to compare or explain an idea. Physical model – Look like the thing they represent 6) What is an intended benefit in technology? The positive purpose for which a technology is designed to be used. 7) Define bioengineering – Application of engineering to living things. 8) What does each tool measure? Triple beam balance - Mass Spring scale - Force Meter stick - Distance Graduated cylinder - Volume

11. Benchmark Study Guide Answers 9) Give 2 examples of each Adaptive bioengineering 1. Cochlear implant 2. Hip replacement Assistive bioengineering 1. Glasses 2. Crutches 10) Where does the scientific name of an organism come from? Its Genus and species 11) What do you follow steps to identify an organism? Dichotomous Key 12) What are the 8 levels of classification from general to specific? Domain, Kingdom, Phylum, Class, Order, Family, Genus, species.

12. Benchmark Study Guide Answers 13) Define Natural Selection – Individuals that are better adapted to their environment survive. (Survival of the fittest) 14) What were the effects of a decrease in genetic variation in the Florida Panther population? Heart defects and a failure of reproductive organs. 15) What are some examples of camouflage? Stripes or patterns on their fur, change color to blend in with its environment. 16) Define Adaptation – A characteristic that improves an individual’s ability to survive and reproduce in a particular environment.

13. Adaptation Model Lab Since the beginning of life on Earth, species have had special characteristics called adaptations that have helped them survive changes in environmental conditions. Changes in a species’ environment include climate changes, habitat destruction, or the extinction of prey.

14. These changes can cause a species to die out unless the species has a characteristic that helps it survive. For example, a species of bird may have an adaptation for eating sunflower seeds and ants. If the ant population dies out, the bird can still eat seeds and can therefore survive.

15. In this activity, you will explore several adaptations and design an organism with adaptations you choose. Then, you will describe how these adaptations help the organism survive.

17. Procedures: 1.Look at the chart on page 90. Choose one adaptation from each column. 2.Design an organism that has the three adaptations you have chosen. You may NOT draw an animal that already exists. You must create your own! Use white copy paper and colored pencils or markers to create your organism. 3.Give your organism a two-part “scientific” name that is based on its characteristics. Write the name at the bottom of your paper. 4. Write a caption on the back of your paper describing your organism. Describe its appearance, the environment or habitat your organism would most likely survive (in the desert, tropical rain forest, plains, icecaps, mountains, or ocean), what it eats, and the way its adaptations help it survive.
