The Science Sense Teacher is happy to offer a download that includes 12 cards that offer students a quick glimpse of different types of scientists and what they might do for a profession. These cards can be used to enrich, remediate, or just get additional practice. While this product is intended to be a colorful, interactive bulletin board, it could also be used as task cards or any other practice method you'd like to use. There is a chart to record the different types of scientists, what they do, and students must decide on what types of sciences they are interested in.
I like to have one required activity that all students participate in every day and then offer time for "choice pieces" which allows the students to decide which activities they will engage in to enrich their knowledge of the subject. I often use an interactive bulletin board as one option for the students.
