Presentation Transcript

  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: • 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organsystem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
