Cupid is packing sweet messages, but why do some hearts vanish in the rain while others survive the storm? It’s not magic—it’s a hidden structural secret that connects a sugary treat to the Earth's crust.
In this investigation, your students will uncover the invisible difference between "grainy" and "smooth" that changes everything.
From Candy to Crust Your students might start by thinking they are testing sweets, but they are actually modeling complex Earth Science concepts.
- The Mystery: Why does the grainy heart dissolve so much faster?
- The Discovery: Pupils will investigate the hidden properties of materials in real-time, discovering how tiny, invisible gaps control the flow of water.
- The Connection: We take that "Aha!" moment and apply it directly to geology. Just like the candy, the difference between a porous sandstone and a non-porous granite dictates how water moves through our planet.
Curriculum Concepts You’ll Cover: This is not only a fun filler activity; it connects directly to key science topics:
- Year 3 Rocks: Compare rocks based on permeability.
- KS3 Earth Science: Understand porosity and the particle model.
- KS4 Rates of Reaction: See how surface area affects dissolving rates.
- Working Scientifically: Variables, predictions, and recording data.
