Agenda 9/4: no homework. Robotics Club starts on 9/10 Warm-up: Read your cornell notes on Controlled experiment cornell notes and add at least two side notes. Table of Contents for Interactive Notebook Unit: 1 ( Chapter 1,2 &3) Left side items Page Right side items page Practice Variables 18 Variables Cornell notes 19 Create an experiment on better tasting cookies 20 Controls and variables part 2 21 Controlled experiment practice 22 Controlled experiment Cornell notes 23

2 Warm-up: What would be an independent variable (the cause) and dependent variable (the effect) in the movement of a jelly fish?

3 Con Standard 9c: Variables 22 121 Warm-up: Read your control and variables on page 21 and make sure all 4 situations are finished. Controlled Experiments A student wants to know if listening to his headset during homework will improve his test scores. He sets up one group that listens to music and one group that does not listen while studying. He compares the score on the same test. 1. 1. Control group Experimentgroup IV present Constants 2. Identify the independent and dependent variables.

4 Essential Question (Objective):
Science Standard 9c. Distinguish between variable and controlled parameters (constants) Essential Question (Objective): What is the relationship between a control group and an experimental group?

5 I. Observations Using your senses to describe the object.
Standard 9c: Variables 23 121 EQ: What is the relationship between a control group and an experiment group? Questions: I. Observations Using your senses to describe the object. A. Write your observations on what you see happening in the jar. Draw an image of your observations also. Three questions created at least one level 3 = 3 pts

6 Variable Independent Variable Dependent Variable
Standard 9c: Variables 23 121 EQ: What is the relationship between a control group and an experiment group? Questions: Notes: II. A = change List the independent and dependent variables on what you think is causing the raisins to move. Variable Independent Variable Dependent Variable (the cause) (the effect) Write your hypothesis here. If___cause_ then_effect___ because_______.

7 Controlled experiment
Standard 9c: Variables 23 121 EQ: What is the relationship between a control group and an experiment group? III An experiment that has only one independent variable. A. Design a controlled experiment on your hypothesis about the movement of raisins in the jar using a Venn Diagram. Describe your control group and experiment group in the Venn Diagram. Controlled experiment What you keep the same between groups Control group Constants Experiment Group Used to compare- NO Independent variable present the independent variable is present

8 Controlled experiment
Standard 9c: Variables 27 121 Revision=Underlined/numbered main ideas (different color of ink). Highlight key vocabulary. Little notes/ diagrams included.= 2 pts. III An experiment that has only one variable. A. Design a controlled experiment on your hypothesis about the movement of raisins in the jar using a Venn Diagram. Describe your control group and experiment group in the Venn Diagram. Controlled experiment Grading: Three questions created at least one level 3 = 3 pts Control group Constants Experiment Group Summary: Answered the EQ question and answered the questions that you created. Have at least one transition word. = 5 pts total.

9 Essential Question (Objective):
Science Standard 9c. Distinguish between variable and controlled parameters (constants) Essential Question (Objective): What is the relationship between a control group and an experimental group?
