The hypothesis is that infrared light will have a higher temperature than visible light.

You will need to blacken the bulbs of the thermometers, place a white piece of paper at the bottom of a cardboard box, rotate the prism until a good wide spectrum appears on the white paper, and place the thermometers in the spectrum.

You will need an equilateral glass prism, 3 alcohol thermometers, scotch tape, a white piece of paper, and a south facing window sill or a box.

This experiment showed that the dark area had a much higher temperature than the areas which were in regions of light. This discovery was important because it led to the realization that there are many other types of light that we cannot see and the visible colors are only a very small part of the entire range of light which we call the electromagnetic spectrum.

This science project is interesting and unique because it allows students to explore the invisible light called infrared and measure its temperature.

Experiment variations to consider include changing the width of the spectrum, which depends on time of day, and the distance from the prism, which is proportional to the height of the box.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
