Who is this for?
Suggested ages 6-9 with adult support. An adult selects samples and controls any flashlight.

Light Through Materials : one PDF with 20 total pages. Guided indoor picture-clarity and light-passage checks, observation records, repeat comparison, fictional evidence cards, one-layer/two-layer discussion and caregiver notes. Use two kinds of evidence rather than guessing from a material name. Keep the setup steady and label uncertainty honestly. Compare actual samples without claiming every plastic or paper behaves alike. Page counts include covers, guidance and answer or support pages; they are not counts of unique activities.
This listing contains one original PDF. Future bundles may include this same file; check component titles before purchasing more than one listing. This is a separate learning resource, not the free 15-book family coloring bonus. It is not a complete curriculum, assessment, therapy or guarantee of progress.
Print selected pages and check your printer preview. A compatible PDF reader, paper and a pencil are needed; printing and all physical supplies are not included.

A CLOSER LOOK
Suggested ages 6-9 with adult support. An adult selects samples and controls any flashlight.
Use only a cool LED flashlight with secured battery compartment and adult-selected large smooth samples. No Sun viewing, lasers, UV lights, flames, hot lamps, glass, plastic bags or lenses. Never aim at eyes or cover a face. Results depend on actual samples. Flashlight, samples and other physical materials are not supplied.
