Can Peanuts Heat Water?

Can Peanuts Heat Water? | Science Fair Projects | STEM Projects
Have you ever wondered if peanuts can be used to heat water? In this project, you'll use a peanut to heat a container of water and measure the energy released.


The hypothesis is that peanuts contain enough energy to heat water.

Method & Materials

You will use a needle and cork to attach a peanut to a skewer, place it in a large can, and then measure the temperature of the water in a small can.
You will need a small bag/can of unsalted, shelled peanuts, a cork, a needle, a large metal juice or coffee can, a small metal can (like a soup can) with paper label removed, a can opener, a hammer, a large nail, a metal BBQ skewer (like the kind for kebobs), about a cup of water, a thermometer, some matches or a lighter, a piece of paper and pencil to record your observations, and a scale.


The experiment showed that the chemical energy stored in the peanut was released and converted into heat energy, which raised the temperature of the water in the small can.

Why do this project?

This science project is interesting and unique because it shows how a tiny peanut can be used to heat a container of water.

Also Consider

Experiment variations to consider include using different kinds of peanuts or other kinds of nuts, and using more than one peanut.
