This homework assignment provides six choices that cover scientific investigation topics. Topics included are variables, steps of the scientific method, and observations. There are a variety of choices from artistic to writing. With choices given, I find that many more of my students complete homework on a weekly basis. They like that they have some control over the assignment and the differentiation is there to play to students strengths. I have left the directions open for you to fill in how many assignments you'd like for your students to complete. I usually ask for two.
