Free Heat Basic Skills Worksheets for grades 3–5. Metal and wood can share a temperature yet feel different to a hand. Sizzling uses this kind of puzzle to separate temperature from heat and explain conduction, convection, radiation, and insulation.

This six-page packet includes two teacher-guide pages, three student worksheets and an 18-point answer key. Students practice 16 tasks: matching, fill-in, classifying cases, multiple choice and explaining evidence. Print the three student pages; keep the guide and key for instruction. No kit or purchase is required.
Meet Sizzling
Gemlings teach science through their personalities and home realms. Sizzling guides learners in Frostfire Lodge. The character’s teaching note introduces the science mission, and the final encouragement recognizes the student’s learning.
Science topics
- Heat, Temperature & Change
- Conduction
- Convection
- Radiation
- Heating, Cooling & State Changes
- Insulation & Thermal Design
Simple classroom use
Allow about 20–30 minutes or split the work across lessons. Model the toolbox words and read the case cards aloud when helpful. Students match clues, complete ideas, classify cases and explain evidence. Use the answer key to discuss corrections; accept accurate explanations in a child’s own words. Tasks 1–14 earn one point each and tasks 15–16 earn up to two each.
Plan a paper investigation comparing two insulated containers. Students identify the measurement, controlled conditions, and success criterion before tracing where energy would move. The lesson also works with teacher-provided temperature data.
A science teaching tip
Heat is energy in transfer, not a substance stored in an object. Warm fluids can rise because of density differences; energy does not always move upward. Insulation slows transfer rather than creating cold.
Train, refresh, then assess
Start with free subject vocabulary training or the free subject reading resource. After worksheet practice, open the subject Adventure page to watch the Gemling video for learning or a refresh, then take the free Online Adventure assessment. The worksheet score is classroom practice, separate from that assessment.
Optional hands-on discovery
Dig Kits can extend Discover–Identify–Collect: uncover specimens, identify them using observations and available specimen/trading cards, and organize a collection. Free worksheets and Online Adventures stand on their own. Teachers may purchase available kits, explore the Free Dig Kits campaign, or ask about possible PTA/PTO funding. Signup does not automatically guarantee free kits; current funding and fulfillment conditions apply. PTA/PTO funding is not guaranteed.
