  1. Objective: • Today we will… • Review control groups • Stations to Practice for Tomorrow’s Test • So that we will be able to… • Design scientific investigations using TQs, IVs, DVs, CVs, and control groups. • Distinguish between observations & inferences when we collect data. • Write evidence-based conclusions for our investigations.

  2. Brainstorm: Zoe jogs every morning. She notices that the sun also rises every morning. She collects the following data: She concludes that the sun rises because she jogs. Is this a reasonable conclusion?

  3. Control Group: • A separate group in which you do not use the IV • Shows what would have happened under “normal” conditions • After the experiment, we can compare our results to our control to see if the IV actually had any effect

  4. Control Groups: Zoe adds a control group to her investigation. How does this change her data? How does this change her conclusion?

  5. How to Choose Your Control:

  6. How to Choose Your Control:

  7. Control Group vs Controlled Variables Amanda wants to see if watching Sesame Street helps young children learn their ABC’s. She takes a group of 20 four-year olds and has them watch 1 hour of Sesame Street each day. After 1 year, she tests them to see if they can say their ABC’s. CVs: Control Group:

  8. STATIONS: Our Unit Test is TOMORROW! The problems at each station are the SAME TYPES of problem of that you will see on your test. So, this is a great opportunity to test yourself and see if you feel prepared. If you finish a station early, please work on your study guide!

  9. Closing: As a table, please answer the following questions: • What are the best things to do to study tonight? - Rework the problems from today’s stations - Answer questions on the study guide 2) Where can I find the practice problems from today’s stations? - All materials are on the class website 3) True or False: I can reassess if the unit test does not go well. - FALSE! Unit tests are the final assessment for a unit. After the unit test, we move on.
