Facilitation guidance from the lesson plan — what to notice in student thinking and how to respond while teaching.
Building towards
7.A Plan and carry out an investigation using a cart on a track to determine how changing the distance between two magnets affects the amount of energy transferred from the field between them.
What to look / listen for
Making Sense of Your Investigation Results is fundamental in developing the following student ideas:
- Energy transfers from the magnetic field into the magnets to make them move.
- Energy transfers out of the field and into the magnets for both attractive and repulsive forces, even though the direction of the movement is different.
What to do
Collect this handout at the end of the lesson and check that students are developing these ideas. If necessary, spend time at the beginning of Lesson 8 or 9 reinforcing these ideas by going through Making Sense of Your Investigation Results together as a class. Leave feedback in the form of noticings and wonderings in the student notebooks for any area of their investigation plan that students did not develop fully.
