Chocolate Melt Lab

Matterville Snack Science: Chocolate Melt Lab is a playful, hands-on chemistry lesson where kids explore heat transfer, exothermic and endothermic processes, melting point, physical change, states of matter, and mixtures — all through chocolate, movement games, and Minute-to-Win-It style challenges.

Designed for homeschool groups, co-ops, micro-schools, outdoor classrooms, and multi-age families, this activity pack turns science vocabulary into an active, memorable experience. Kids predict which chocolate will melt fastest, play station-based energy transfer games, sort exothermic vs. endothermic examples, observe chocolate changing from solid to liquid, taste test results, and record their findings at three different learning levels.

This pack works especially well for mixed-age groups because everyone participates in the same core experiment, while the lab sheets offer different levels of depth for littles, elementary students, and older learners.

What’s included:

• Guide setup tips for parent helpers and station flow
• Teacher guide with Matterville story, wonder questions, vocabulary, and discussion prompts
• Day-of quick reference sheet
• Chocolate Melt Lab group wall chart for predictions, tallying, graphing, and results

• Roll & Transfer Dice event cards and game board
• Velcro Sort board and sorting cards
• Preschool Discovery Station
• Thermometer reference card
• Iggy the Igniter vocabulary cheat sheet
• Level 1 Littles Lab Sheet
• Level 2 Core Scientists Lab Sheet
• Level 3 Big Scientists Lab Sheet
• Built-in prompts for observation, prediction, graphing, and reflection

Science concepts covered:

• Exothermic vs. endothermic processes
• Heat transfer
• Melting point
• States of matter
• Solid to liquid changes
• Physical vs. chemical change
• Particles
• Combustion
• Oxygen and fuel
• Pure substances vs. mixtures
