We’ve all been there: the tragedy of a biscuit that breaks off mid-dunk. Cupid wants to avoid this heartbreak, but which shape can hold the most milk without crumbling?
In this tasty investigation, your students will finally find the scientific justification for their favorite snack habits.
The "Soggy" Science at first glance It looks like breakfast, but it's actually physics in action.
- The Mystery: Why do some biscuits soak up milk instantly while others stay dry?
- The Experiment: Students will race against the clock (and gravity!) to measure absorption rates, testing which shapes act as the best sponges.
- The Science: It's all about capillary action. Students will see how tiny pores act like invisible straws, drawing liquid in based on surface area.
Curriculum Concepts You’ll Cover Connect the snack break to serious science:
- KS2 Properties of Materials: Absorption and stability.
- KS3 Particle Model: Understanding capillary action.
- KS4 Rates of Reaction: Surface area to volume ratio.
