Who is this for?
Suggested ages 6-9 with an adult checking equipment and supervising throughout.

Shadow Changes Investigation : one PDF with 22 total pages. Original setup diagrams, four guided comparisons, recording spaces, fictional practice evidence and caregiver explanations: object distance, light distance, card orientation and side-to-side light movement. Keep a baseline while changing one position at a time. Distinguish changing the card from changing its shadow. Use real observations and identify unclear edges or setup limits. Page counts include covers, guidance and answer or support pages; they are not counts of unique activities.
