Insulating Boiling Water

Insulating Boiling Water | Science Fair Projects | STEM Projects
Let's explore how different materials can keep boiling water hot. We'll measure the temperature of boiling water in different containers and see which materials keep it the hottest.


The hypothesis is that some materials will be better insulators than others.

Method & Materials

You will fill several containers with boiling water and measure the temperature with a thermometer every hour or two.
You will need a thermos, several jars, boiling water, and a thermometer.


Our experiment showed that some materials are better insulators than others. The best insulator was the thermos, which kept the boiling water the hottest for the longest amount of time.

Why do this project?

This science project is interesting because it allows us to explore how different materials can affect the temperature of boiling water.

Also Consider

Experiment variations to consider include testing different thicknesses of insulation materials and testing combinations of materials.
