Investigating Why Some Materials Stick

Students introduce themselves to the partner class, then predict which everyday objects will stick to a magnet and why. Teams record their guesses before testing begins.

Teams test a range of everyday objects with bar magnets, record which ones attract, and check whether flipping the magnet's poles changes the pull. They share their results with the partner class and compare patterns across both countries.

Using combined data from both classes, students look for patterns, decide whether the magnet rules hold for different objects, and identify any results that do not fit. They write a short explanation supported by evidence.

Each team presents its strongest finding and whether the rules held across both classrooms. Students reflect on what surprised them and what they would test next.
