Thermal Energy Experiment – A Hands‑On Way to Explore Heat Energy

If you’re looking for a simple, high‑impact way to help students see how heat moves, this Thermal Energy Experiment is going to be your new favourite go‑to. With this Thermal Energy Experiment pack, students get the chance to observe the movement of heat particles in hot and cold water…something that’s way easier to understand when they can actually watch it happen. The resource makes it easy to guide students through the experiment, record observations, and build a solid understanding of heat energy.

What’s Inside This Heat Energy Science Experiment Pack

To complete this activity, students will:

• Review what they know about heat and how heat energy moves.
• Make a prediction about what will happen when food coloring is dropped into hot water and cold water.
• Place three large drops of food colouring into each glass of water.
• Watch what happens to the food coloring in each glass over the next few minutes. Record what they observe.
• Compare the results between hot and cold water and explain what their observations show about heat energy.
