FAQ

What does light sources teach first graders?

First graders learn to distinguish between natural and human-made sources of light and to understand that all light comes from a source that produces energy. They explore examples from the sun and stars to candles and screens, building awareness of how much light shapes their daily experience.

When do first graders learn about light sources?

Light sources are typically introduced in Grade 1 during a physical science unit on energy, sound, and light. Teachers often use darkened rooms or blackout tents so students can dramatically observe the difference between having a light source and not having one.

How can I use these worksheets at home?

Do a light source hunt around your home in the daytime and then again at night, listing every source of light your child can find. Complete the worksheet together by sorting sources into natural and human-made categories.
