Quick check
Measurable exit ticket
Exit ticket: draw a light source, an object, a screen, and the resulting shadow. Add arrows for light direction and write one sentence explaining why the shadow forms.
Try one more thing
Extension activity
Create three shadow outlines by changing the position of one safe object relative to a flashlight and wall. Label the source, object, and shadow in each drawing, then describe one pattern you notice.
Teacher and tutor note
Classroom adaptation
Set up stations with a flashlight, screen, and safe transparent, translucent, and opaque materials. After the puzzle, groups predict and record how each material changes the light or shadow, then share one evidence-based comparison.
Differentiation and accommodations
Extra support
Use the Easy grid, preview each object with a picture, and trace the light path with a finger before searching.
More challenge
Use the Challenge grid and explain how distance and angle can change a shadow's size, position, or shape.
Access options
- Offer high-contrast materials and a larger printed grid.
- Allow oral predictions and observations instead of written sentences.
- Avoid flashing lights and provide a static diagram for learners with light sensitivity.
Accessibility
All vocabulary, definitions, and directions appear as selectable HTML and can be enlarged with browser zoom. The PDFs are visual and untagged, and the optional flashlight investigation should be replaced with a static high-contrast diagram for learners sensitive to light.
