For the experiment today we learn about how various material conduct heat differently. Can you guess which bead will move down the spoon? Hint – Which material conducts heat better, wood, plastic or metal?
Conducting Heat Science Experiment Video
- Small Glass Bowl
- Three Spoons (1 made out of wood, 1 made out of plastic and 1 made out of metal)
- 3 Beads
- Boiling Water
Step 1 – Begin my positioning 3 spoons in a small glass bowl.
Step 2 – Place a small pat of butter at the top of each spoon
Step 3 – Put a bead in each pat of butter
Step 4 – Carefully pour hot boiling water into the bowl until it is almost completely full. Be careful not to allow the spoons to fall into the bowl.
Step 5 – Watch carefully to see what happens to the beads. Note: You will likely need to watch the experiment for 5-10 minutes before anything happens.
How Does the Experiment Work?
Conduction is the way that heat moves though a solid objects. In our experiment, we tested three different types of materials (Metal, Wood and Plastic) and found that metal conducts heat better than plastic and wood.
When we placed the spoons in the boiling water, the heat from the water was transferred to the handle of the spoons. Because metal is a good conductor, the heat in the handle of the spoon moved to the top of the spoon. When this happened, the butter at the top of the spoon began to melt and slide downward.
I hope you enjoyed the experiment. Here’s some printable instructions.
