This is another differentiated homework assignment for scientific investigation topics. Topics include variables, observations, inferences, and hypotheses. There are 6 choices for homework assignments so that each child can find something that interests them and fits their strengths. I usually have my students choose 2 assignments to complete. I have left this blank, however, so you can choose the amount for your students to do. I find that my students are much more motivated to complete the homework when they feel they have some control over the assignment.
