This scoring can be most quickly accomplished if one science teacher rates all students' responses to Station 1 while another rates all students' responses to Station 2 and a third rates all students' responses to Station 3. Each student will spend 15 minutes at each of the three stations during the testing period. Detailed information on the equipment, materials preparation, and station setup will be provided at the regional workshops. Students will make microscopic observations and measurements of a real organism and use their key to classify that creature. Students will be asked to make inferences and predictions based on the data they collect.
Students then make additional observations and predictions related to the objects' densities.
It is possible to set up one testing room with 8-12 groups of three stations each.
