Mendel's Inheritance Experiment

Understand how heat is transferred in liquids by convection currents

The activity demonstrates heat conduction by comparing copper and iron. Small nails fixed with wax on both metal rods fall as the rods are heated. The copper nail falls first, showing that copper conducts heat faster than iron and highlighting the role of material type in heat transfer.

The objective of the activity is to classify the things around us into non-living things, animals, humans, and plants
