1. EDP, charts, variables, body systems TCAP review most important info

2. Engineering Design Process

3. You tube video http://youtu.be/6PJTlzY0Aak

4. Independent/Dependent Variable Independent variable: the thing you are CHANGING in the experiment Dependent variable: what happens as a result of this change ex) I want to know which detergent works the best so I was the same tee shirts with the same mustard stain for the same amount of time. I was 1 shirt with Tide and the other with Gain. What is the independent variable? Dependent variable?

5. Setting Up Experiments You can only change 1 thing at a time!!!!

6. Sponge bob examples Flower power: what did he do wrong? Microwave Miracle: – What is the control? – What is the ind. Variable? – What is the dep. Variable?

7. Reading a table/chart/graph Always read the title and any info that they give you Look at what is being compared Figure out the relationship between what is being compared – Ex)as one goes up, the other goes down OR they are both going up OR they are both going down

8. Graph/table practice See sample TCAP question #2

9. Identify the graph that matches each of the following stories: I had just left home when I realized I had forgotten my books so I went back to pick them up. Things went fine until I had a flat tire. I started out calmly, but sped up when I realized I was going to be late.

10. Bias An experiment is biased if: 1.The research was not done well Too many variables Not enough trials 2. The researcher has a personal connection with the experiment See #30 on document reader

11. bioengineering engineering mixes with living things Can be assistive or adaptive assistive= helps organisms do things better (pace maker, contact lenses, crutches) Adaptive= changing a product or process to work for certain disabilities ex) computer keyboard that works by a person tapping it with a tube

12. Flow Chart *must know* Cells  tissue  organ  organ system  organism

13. Body Systems Respiratory: oxygen in, carbon dioxide out Cardiovascular: pumps blood through body Endocrine: glands released hormones (adrenaline) Nervous: controls everything, sends messages through body Integumentary: skin, nails, hair (protects body) Muscular: helps you move Skeletal: supports your body and movement
