Heat Practice Activities
Printable Class 1 Science and EVS heat activities for identifying hot and cold things, heat sources, simple effects of heat, and safe behaviour.
Practice that builds confidence
From hot and cold to heat sources
These Class 1 heat practice activities help children understand heat through everyday experiences: a hot cup, the warm sun, ice melting, wet clothes drying, and food being cooked. Children practise using words such as hot, cold, warm, cool, heat, and heat source in a safe, age-appropriate way.
The printable worksheets include picture-based sorting, matching, circling, colouring, and simple observation tasks. They are designed for early Science and EVS learning within the Energy, Sound and Light area, with clear visuals that support children who are still developing reading confidence.
Class 1 children first notice heat through touch and daily routines, so the worksheets begin with familiar comparisons: hot tea and cold juice, a sunny day and a cool fan breeze, warm food and ice cream. They then move towards identifying heat sources such as the sun, a stove, a candle, and a heater, while also learning that some hot objects are not safe to touch.
Concepts children practise
Activities build the idea that heat can warm things, dry things, melt some things, and help in cooking. A child may match the sun to drying clothes, circle the object that melts, or colour the picture that shows a safe way to stay warm. The focus stays on observation and vocabulary, not complex measurement. Useful words include hot, cold, warm, cool, melt, dry, cook, burn, safe, and unsafe.
A simple parent routine
At home, use one worksheet page with a real-life talk. Ask, “Which things in our kitchen become hot?” or “What happens to ice when it is left outside?” Let the child answer first, then connect the answer to a worksheet picture. Reinforce safety by saying, “We can look, but we do not touch hot things without an adult.” Finish by asking the child to name one hot thing, one cold thing, and one thing that gives heat.
Classroom uses for teachers
Teachers can use these printables after a class discussion on the sun, cooking, clothes drying, or winter clothing. They also work well in EVS centres, picture-talk lessons, notebook pasting, or quick revision before moving to sound and light. Pair work is useful: one child points to a picture, while the other says whether it is hot, cold, a heat source, or an effect of heat.
Common errors and a child-friendly strategy
Children may call every bright object a heat source, confuse warm and hot, or think cold objects have “no temperature”. They may also forget safety rules around fire, irons, or boiling water. Teach the strategy: “Look, think, then say.” Look at the picture, think whether it gives heat or only feels warm, then say the safest answer.

After the child completes the worksheet independently, parents and teachers can use the answer support or answer key information to check the work, review mistakes, and choose the next practice step.
Why iBloom worksheets help
The worksheets use clear pictures, small task steps, and repeated vocabulary so children can connect science words with real objects. The mix of sorting, matching, and observation keeps practice active while helping Class 1 learners build careful, safe understanding of heat.
Helpful answers
Frequently asked questions
What heat concepts are suitable for Class 1 children?
Class 1 children can learn to identify hot, cold, warm, and cool things; name common heat sources like the sun and stove; observe simple effects such as melting, drying, and cooking; and follow basic safety rules.
Do these worksheets teach temperature measurement?
No. These activities focus on everyday observation and vocabulary. Children compare hot and cold objects but do not need to read thermometers or measure temperature.
How can I explain a heat source to a young child?
Say that a heat source is something that gives heat. Use familiar examples such as the sun, a stove, a candle, or a heater, and remind the child that some heat sources are unsafe to touch.
Are safety topics included in the heat activities?
Yes. The worksheets encourage children to recognise hot objects and unsafe situations, such as touching fire, boiling water, irons, or hot utensils without an adult.
Can these printables be used in an EVS lesson?
Yes. They fit well in Class 1 Science and EVS lessons about energy, daily life, weather, cooking, clothes drying, and safe behaviour around hot things.
Is this Class 1 heat worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this Class 1 heat worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
Does this Class 1 heat worksheet include answers or an answer key?
When the activity has fixed answers, iBloom includes answer support so parents and teachers can check the completed worksheet.
