A student conducts an experiment to determine which type ofsour candy causes the most dramatic facial reaction when eaten. Experimental Group(A) She uses 3 similar types of sour candy in a series of experiments

(Sour Skittles, Sour Patch Kids, and Warheads). She gives 1 piece of candy to 3 different studentsControl Group(B) Then she uses three types of non-sour candy that look and feellike the sour candy in a series of experiments.(Reg Skittles, Gummi Bears, and Jaw Breakers) Again she gives 1 piece of candy to 3 different studentsIdentify the following:(1) Independent and dependent variable in the experimental group(2) Constants

Experimental group(A) All the details of the series of experiments using the 3similar types of sour candy

Control group(B) All the details of the series of experiments using the 3types of non-sour candy.

Independent and Dependent variables-Independent: The different types of sour candy

-Dependent: The kid’s facial expressions

These are some constants-Gave each person the exact same amount of candy (1 piece)-Used the same 3 students for all the experiments

NOTE: The types of non-sour candy are control variables!

1) Discuss objective and bell work 2) Ask about birthdays 3) Watch Study Jams about the scientific methodLink 01: Study Jams Website Select “science”, then “scientific inquiry”, then “scientific methods”4) Watch/Listen to song about variables and controlsLink 02: Variable Song on Youtube5) Review and discuss one science project (teacher lead)6) Analyze science projects at the work stations Identify the independent variable Identify one dependent variable7) COPY IN YOUR AGENDA: No Homework:
