Provide children with an array of objects that emit light and can be turned on and off as well as objects that don’t emit light. Ask children to help you solve a problem that requires light. Maybe you want to read a book but it’s too dark, or it’s time to clean up, but you can’t find all the toys.

Interactive Lesson

• Provide big button switches for children to press easily to turn lights on and off.
• Add brightly colored tape to an object’s on/off switches.
• Provide visuals for children to support communication.
