Day 2 - Adding Capacity

With some experimental and design experience under their belt, students continue to explore key electromagnet variables. They have now seen how changes in design can yield increased loads. Yet often, in their excitement to produce wildly improved results, students will fail to control variables in the design experiments they conduct. When placed in an engaging context that also requires good scientific methodology, students often, not always, miss the prize. How can this key learning objective become the subject of Formative Assessment is important for planning your Electromagnet lessons.

Students also need to see the gaping differences between making random guesses as to what to do next, and making choices based on data or being informed in other valid ways. What type of decision-making do you see in MOVIE 1?
