Presentation Transcript

  1. Welcome Back! • Same seats as yesterday • Turn in your signed syllabus or code of conduct, (due Friday) • Get out your notes from yesterday to finish • Start thinking about the QOD – What qualifies as science?

  2. First… Let’s finish your notes from yesterday (and please make sure I take attendance!)

  3. Bell Work • In the first section of your notebook, copy the following question and write the answer. • “Name three times you would ‘do science’ in your daily life.”

  4. What qualifies as Science?

  5. Science is… • A method of solving a problem or investigating a phenomenon.

  6. Sci Method Review Bart Simpson believes that mice exposed to microwaves will become extra strong. He decides to perform this experiment by placing 10 mice in a microwave for 10 seconds. He compared these 10 mice to another 10 mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse food. He found that 8 out of 10 of the microwaved mice were able to push the block away. 7 out of 10 of the non-microwaved mice were able to do the same.

  7. Building your Lab Report • Problem/Question: Why are you doing the experiment?

  8. Building your Lab Report • Hypothesis: Make an educated prediction about the outcome using “If ___, then ___, because ___.” • Example: If I put fresh batteries in the remote then it will work because batteries must be replaced regularly.

  9. Building your Lab Report • Procedure: Describe what is done in the experiment in five sentences or less.

  10. Building your Lab Report • Independent Variable: What are YOU changing or testing? • Dependent Variable: What will happen because of the IV change? OR What will you measure?

  11. Building your Lab Report • Control: What will you compare to in order to see the results? (Note: Not always used) • Constant: What will you need to keep the same?

  12. Building your Lab Report • Results: What happened in the experiment? • Quantitative (Numbers) Data: measurements, counts, etc. • Qualitative (Qualities) Data: color, texture, etc.

  13. Building your Lab Report • Conclusion: Evaluate your hypothesis based on the data. Suggest what type of experiment to do next.

  14. Let’s Try it Out • Thumb Wrestling Lab

  15. Homework • On a separate sheet of paper to turn in, fill out a lab report for the Beri-Beri experiment as if you were Dr. Eijkman. Due tomorrow at the beginning of the block.
