The hypothesis is that the reflective bubble sunshade will be the most effective cooling.

You will inspect three cars to make sure they are the same make and model, interior and color. Then you will park the cars directly under the sun and measure the temperatures on the dashboards every two hours. On the second day, you will fit one car with a reflective bubble sunshade, one with a reflective foam sunshade, and leave one with no sunshade.

You will need three cars of the same make and model, interior and color, one reflective bubble sunshade, one reflective foam sunshade, and one infrared thermometer.

The experiment showed that the car with the reflective bubble sunshade had the lowest cabin temperature. This proves that sunshades are effective in blocking the sun's rays from entering the car and reducing the build up of temperature in the car.

This science project is interesting because it shows how sunshades can be used to reduce the temperature in a car on a hot day. It also shows how different types of sunshades can be compared to see which one is the most effective.

Variations of this experiment could include using cars with tinted glass or cars with different colors and sunshades.

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!!
