Exploring Thermal Energy Through Fun Experiments

Mr. C and his science crew explore thermal energy through fun experiments. They demonstrate how heat transfer works using ice and a thermal camera, build a simple thermometer, and explain conductors and insulators. The video also includes a DIY ice cream experiment using rock salt and a thrilling liquid nitrogen demonstration. Throughout, Mr. C emphasizes the importance of keeping a science notebook to record observations and data.

What is the main topic introduced by Mr. C and his science crew?

• Photosynthesis

• Magnetism

• Thermal Energy

• Electricity
