Effect of Temperature on the Dissolving Time of Candy Hearts

Product Description

This Valentine’s-themed investigation explores temperature, dissolving, and rates of processes through a controlled practical task suitable for Key Stage 2, Key Stage 3, Key Stage 4, and homeschool science.

The Valentine’s context boosts engagement, but the investigation is equally suitable at any point in the school year when teaching dissolving or rates.

Learners test how water temperature affects dissolving time, control variables carefully, record results, and explain patterns using particle motion and collision ideas.
