About this worksheet
Make magnets a hands-on mystery with this scaffolded grade 3 investigation. Students become magnet detectives: they predict, then test ten everyday objects, record what really happened, and hunt for the pattern that magnets pull on iron and steel — not all metal, since a penny will not stick.
The lab keeps building. Students feel two magnets attract and repel, discover that a magnet can move a paper clip across a gap without touching it, and finish with a claim-and-evidence sentence frame that has them explain their thinking like a scientist. A motivating Big Question frames the whole sheet and gets answered at the end.
Perfect for a science station, a whole-class investigation, or a STEM lesson. Everything is no-prep beyond simple classroom objects and a magnet. A clean answer key with sample responses is included, and the key skips the data table and drawing boxes to save your ink.
