Heat, Light or Sound

Start with something students can look at or think about: a photo, a short video, a jar on the windowsill, or a question like "what do you already know about light sources?" Then let them work through the first item together as a class, then finish the rest independently or with a partner, keeping a word bank or anchor chart in view so the vocabulary stays available. When you review, ask students how they knew, and let them point to the part of the diagram or reading that told them. These light sources worksheets work well as a lead in before an investigation, as a way to capture what students noticed afterward, or as review before an assessment.

These light sources worksheets for 1st grade give students a clear, visual way to work through one of the big ideas in energy sound and light. Students label diagrams, sort and classify examples, read short explanations, and answer questions that ask them to say why, not just what. Each page keeps the science vocabulary front and center so students leave with the words they need to talk about light sources accurately. Working through light sources on paper gives 1st grade students something concrete to hold onto before, during, or after the hands on part of a lesson.

Yes, both. We made it for 1st Grade energy, sound and light, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with light sources. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

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.

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.

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.

13 printable worksheets, all free to preview. Downloads are included with a ClassWeekly free trial, and every page prints on standard 8.5 x 11 paper.

These are written for 1st Grade students, roughly ages 6-7. Many teachers also use them a grade up for review or a grade down as an extension, so use the preview to judge the fit for a particular child.

Yes. Each one shows the NGSS code it covers on its own page, so you can check the alignment yourself rather than taking our word for it.

Yes. Nothing here assumes a classroom of 25, so they work the same one-to-one at the kitchen table as they do in a 1st Grade classroom, a literacy centre, or a tutoring session.
