Building towards
3.B Construct an argument supported by empirical evidence and scientific reasoning that energy can transfer between magnets without going through matter, causing the magnets to move.
What to look / listen for
Look for students to do the following:
make a claim about how air is not involved in energy transfer
provide evidence from either or both demonstrations
connect the evidence to the claim explicitly by explaining why it supports or does not support the hypothesis that air is involved in energy transfer
What to do
Make note of students who are struggling to connect their claim to the evidence from the demonstrations. Come back to this at the start of the next lesson and ask students to work in pairs to critique each other’s arguments and then revise their own. If there is time, consider having students work in groups of three to develop a consensus argument and share it in a gallery walk, allowing students to leave their critiques as sticky notes on the chart paper. Pair students strategically, putting students with strong explanations together with students who need more support.
