 * 17

What are the steps of the scientific method? 1. Stating a problem, gathering information, forming a hypothesis, experimenting, analyzing the data, and drawing conclusions is the scientific method. What is a hypothesis? 2. A hypothesis is a proposed explanation or prediction that can be tested. What is a theory? 3. A theory is an explanation based on the results of many observations or experiments. Compare and contrast a theory with a hypothesis. 4. A theory is an explanation based on many observations; a hypothesis is a testable prediction. What is an experimental variable? 5. A variable is something that can change in an experiment. Why is it important to allow only one variable to change at a time during an experiment? 6. Experiments should only test one variable because if two are changed, one doesn't know which variable caused the result. What is an independent variable? 7. The independent variable is what the experimenter changes or enacts in order to do the experiment. What does the experimenter manipulate in an experiment? 8. The experimenter manipulates the independent variable. What is a dependent variable? 9. A dependent variable is what changes as a result of the independent variable. How is a dependent variable related to the independent variable in an experiment? 10. The independent variable is said to cause an apparent change in, or affect the dependent variable. What is a control in an experiment? 11. A control is a group of subjects or an unchanged situation to which the outcome of a test is compared. What are controlled variables in an experiment? 12. Controlled variables are anything that could influence the dependent variables. Why are controlled variables important in an experiment? 13. Controlled variables must be carefully monitored and kept equal in your experiments; uncontrolled factors can cause false results. (Uncontrolled variables will mess up your experiment.) How is the control group treated differently than the experimental group.? 14. A control group doesn't experience the independent variable. What is an experimental group? 15. An experimental group are subjects that experience the factor that is change in an experiment. What is a “blind” experiment? 16. When the subjects of an experiment or the person collecting results is unaware of whether a given subject is part of the experimental or control group. Why are “blind” conditions done in an experiment? 17. Placebo affect and experimenter bias are controlled by blind conditions in an experiment. What are the characteristics of life? 18. Organization, having cells, responding to stimuli, homeostasis, metabolism, development, and reproduction are the characteristics of living things. Summarizing the organization found in complex multicellular organisms. 19. Biological molecules are combined and organized to make up organelles. Organelles are the parts of the cell. Similar cells make up tissues. Tissues working together make up organs. Organs that work together make up organ systems. Organ systems make up organisms. What is a cell? 20. A cell is the smallest unit of an organism that can perform all life functions. Give an example of a plant responding to a stimuli. 21. Leaves growing towards light or roots growing downward is a plant responding to stimuli. What is homeostasis? 22. Homeostasis is the maintenance of a stable level internal conditions even though environmental conditions are constantly changing. What is metabolism? 23. Metabolism is the sum of all the chemical reactions that take in and transform energy and materials from the environment. What is cell division? 24. Cell division is the formation of two new cells from an existing cell. Contrast how unicellular and multicellular organisms grow. 25. Unicellular organisms grow through cell enlargement, while multicellular organisms grow mainly by increasing the number of their cells through cell division. What is the difference between growth and development? 26. Growth is just getting bigger, whereas development involves cell division and cells changing into different kinds to perform different functions. Contrast asexual and sexual reproduction. 27. The offspring and parent have identical genes in asexual reproduction, whereas the offspring of sexual reproduction gets a mix of genes from two parents. 28. What is a gene? A gene is a short segment of DNA that contains the instructions for a single trait of an organism.

Assignment # 1...... Scientific Method__

Read the story and answer the questions. Also copy the definition given.

The Scientific Method:
 * State the problem
 * Gathering Information
 * Form a hypothesis
 * Test the Hypothesis with an Experiment
 * Analyzing the Data
 * Drawing Conclusion

State the problem: A pet owner had his four cats boarded while he travels. The cats seemed healthy when they arrived, but a technician notices that two of the cats start scratching and chewing at their skin. After three days, these same two cats have bare patches of skin with red sores. 1. What is the problem?

Gathering Information: The technician knows that cat's sometimes change their behavior when moved to a new place, so she watches all four cats for two days. Other than the scratching and chewing by the cats with sores, the behavior of all four cats seems the same. The technician called the owner and found out that he fed the cats the same food as she did. While observing the cats, the technician also noticed that the cats scratched most after using the litter box. She called the owner and asked what brand of litter he put in the cat's litter box. The owner used a different brand than she did, so she compared the ingredients of the two kinds of litter. The difference was that the owners litter was deodorant free, while the brand she used had a deodorant. 2. What three pieces of information were gathered?

Form a hypothesis: Based on the information gathered, the next thing the technician does is form a hypothesis. 3. What hypothesis should the technician form?
 * A hypothesis is an explanation that can be tested. (Copy this definition)

Test the Hypothesis with an Experiment: The technician gets the cats owners permission to test her hypothesis. 4. How how you would test the hypothesis?

Controls 5. What “control” could you include in this testing of the hypothesis?
 * A control is the standard to which the outcome of a test is compared. (Copy this definition)

Variables 6. What is the variable in this test?
 * A variable is something in an experiment that can change. (Copy this definition)

Analyzing the Data: The technician observes the cats for one week. During this time she collects data. 7. What data should be collected in this test?

Drawing Conclusion: The data show that the control cat scratches and and chews more often than the experimental cat. Does. The sores on the skin of the experimental cat begin to heal, but those on the control cat do not. 8. What conclusion can be drawn from this data?

9. Further testing to be more sure of that the conclusion is correct: 10. How could the control cat be used to support the conclusion? 11. How could the experimental cat be used to verify the conclusion?

12. Would both of these latter tests be ethical on someone's pet?
