Two experiments to visualise heat transfer between sand and water

With these experiments, your students will be able to simulate heat transfer between water and sand.

45 mins to 1.5 hours / 15 students
Type of content:  experimental activity to be done in class
Materials required: two jars or buckets, sand or soil, water, two thermometers


Follow this step-by-step experiment which simulates the scientific approach through observations and measurements.

The difference in temperature between the water and the atmosphere leads to heat transfer through the sun's rays. This experiment shows how heat spreads and is absorbed and released by water and earth (represented by sand in this experiment).

Therefore, you will find at your disposal an experimental protocol containing the steps to follow as well as questions related to heat transfer in the earth system.
