Due 10/3/14
Unit 1 Post-Test
 The Post-Test is 16 questions long.
 It has a total of 34 parts of the test.
 Unlike before – this test counts.
Experimental Design Analysis
 Before the review game, I’d like to go
over an experimental design analysis
question.
 Let’s take a look at one of the Unit 1
Transfer activities.
Unit 1 Post-Test
 Topics Covered:
The Road Map of Science
Hypotheses
 Independent/Dependent Variables
 Experimental Design

Envi. Sci. Terminology
Experimental Design/Analysis
Review Game
 Work in your groups to complete the
problems as quickly and correctly as you
can.
 Answer the question on the back of the
Post-It note.
 When you finished with your answer,
come up to the board and place your
Post-It in the column for your group #.
