  8. Directions • Take one handout from the front of the class • Sit at the desk with the number that matches your card • Get started on thebellringer. You have 7 minutes from when the tardy bell rings

  9. Table of Contents 80+  MASTERY (Y for Yes) Below 80  NO MASTERY (N for No)

  10. Bellringer: share out 1. A doctor wants to know if eating carrots improves your vision. He gets 50 of his patients to eat raw carrots every night before dinner, and 50 of them to continue with their regular diet. He then tests their vision after 2 months. a. What was the one thing that the doctor changed between the 2 groups of people? b. What would happen if one of the groups of people happened to be a lot older than the other group? How would this affect the doctor’s results?

  11. CITE evidence

  12. What is a variable? • A variable is anything that changesin a scientific experiment

  13. Example The Question: Ms. Rekart’s class wants to know… does smell affect how well you can taste? Their hypothesis:

  14. 3. Their experiment: They decide to pick a volunteer from the class, ________________, to try to guess the color of skittles with his/her eyes closed! First, he/she will try with his/her nose plugged---then, he/she will get to use smell! They will then see if smell affected taste.

  15. What kinds of variables are there? • There are 3 types of variables: independent, dependent, and control. • The independent variable is the one that changes first, or the one that you change. In our experiment, what was the independent variable?

  16. The dependent variable depends on the independent variable In our experiment, what was the dependent variable? ______________________

  17. The control variable(s) are things that we try to keep thesame. What stayed the same between the two tests? _____________________________________________________________________________________________________________________

  18. Practice 1. Jose wants to know if feeding his puppies expensive food will make them fatter. He gets 2 identical puppies and feeds one expensive food and one regular food. What is the independent variable: ____________________________ What is the dependent variable: ____________________________ What is/are the control variable(s):

  19. A scientist wants to know how the type of light affects the height of a plant. She gets 2 bean plants and gives one direct sunlight and one artificial light. What is the independent variable: _____________________________ What is the dependent variable: ____________________________ What is/are the control variable(s):

  20. How do we graph variables? • The independentvariable always goes on theX-axis (the bottom of the graph) • The dependent variable goes on the Y-axis (the side of the graph)

  21. Example: Let’s graph our skittles experiment!

  22. Example 2

  23. Class Rewards and Consequences Rewards: For exhibiting the 5 Cs • Music during independent practice • Cool science demo • Group activity on Friday • Class-appropriate YouTube video

  24. Consequences • Verbal Warning • Loss of ½ participation points • Move seats and call home • Office referral

  25. More Procedures!!! • Missing work and tardies

  26. Exit Ticket • 5 minutes • Work along (class should be silent) • No notes • When you are finished, place in the bin at the front of class and put binders up
