  1. Science Starter- 9/14 Consider the following and answer the questions in your notebook: Scientists in City A spent two hours one evening catching fish in a stream using an experimental new bait and caught 5 fish, while scientists in City B spent three hours one morning catching fish in a lake using the same bait and caught 2 fish.  They could not reach any conclusion about how many fish a person can catch using the bait.  1.    What are the factors that led to the different results? 2.    What are some practical ways the scientists could reduce variation?

  2. Plot you classes Data • I will wait only a couple of minutes . . . • Then answer the question . . . • -Do you think your class’s data is reliable? -Why or Why not?

  3. Define:-Repeatable-Replicate-Distribution/VariationDiscuss what these words have to do with our data.

  4. Reflection:-Do you think you can design a procedure so that everyone gets the same results?*Talk with your group to come up with some procedures, then we will bring it together as a class.*

  5. New Procedures BLK 1 • Must drop on tales • Pipette must drop

  6. New Procedures BLK 3 • Same type of penny • Do 2 trials of heads and two with tails • Have pipette close to penny • Penny must be on flat surface (on table)

  7. New Procedures BLK 4 • Must drop on tales • Pipette will be ¼ full when in use • Drops will be at the same rate (on Diana’s count) • Drop must be in center • Pipette must be vertical • This class is not done. We will finish list on Monday.

  8. New Procedures BLK 5 • Same size pipette • One drop at a time • Same amount of water in pipette (How much) • This class is not done. We will finish list on Monday.
