Heat Race Weather Science Experiment
In this fun and easy science experiment, we’re going to explore and investigate weather by determining if land or water heats up faster.
Materials:
- Two plastic cups
- One half cup of water
- One half cup of soil
- Thermometer
Instructions:
- Pour the water into one cup.
- Pour the soil into the other cup.
- Place both cups in the refrigerator for 10 minutes.
- Next place both cups in the sun for fifteen minutes.
- Record the temperatures of the both the soil and water and determine which heated up more.

How it Works:
Land has the ability to absorb more solar radiation than water because water will reflect most solar radiation back into the atmosphere. Since land absorbs more solar radiation it will warm more quickly than water. A large body of water has a higher heat capacity than land, meaning it takes more energy to warm and cool the temperature of water. Because of this, cities situated close to water will often have a tighter range of temperatures throughout the year as compared to cities situated more inland.
Make This A Science Project:
Try adding salt to the water. Try different types of land materials like rocks or sand. Try freezing the soil and water before sitting them in the sun.
