Hot or cold?

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 heat?" Then let them work through the worksheet on their own 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 heat 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 heat worksheets for Kindergarten give students a clear, visual way to work through one of the big ideas in energy. 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 heat accurately. Working through heat on paper gives Kindergarten students something concrete to hold onto before, during, or after the hands on part of a lesson.

This worksheet is designed for Kindergarten students (Ages 3-6), aligned to NGSS standard K-PS3-1. It can also be used as review for early students at the next grade level or as an introduction for advanced students.

Yes. This worksheet works for homeschool, classroom, and tutoring settings. Print individual pages for targeted practice, or print the full set as a packet. Works great as a morning warm-up, independent center activity, or fast-finisher task.

Heat worksheets teach kindergartners that heat is a type of energy that makes things feel warm or hot. Children identify sources of heat in their environment, learn that heat can melt, cook, or warm objects, and explore the difference between things that produce heat and things that keep heat in.

Heat is introduced in kindergarten physical science as part of an energy unit, often alongside lessons on light and sound. The concept is approached through everyday examples children already understand, like feeling the sun on their skin or watching ice melt.

Point out heat sources in your home, the oven, radiator, sunlight through a window, and connect them to worksheet concepts. A simple activity like comparing ice left in sunlight versus shade gives children a memorable, hands-on experience of heat energy.
