Science Friday: Rainbow Rain Clouds
It’s Friday which means it’s time for another science experiment! In this experiment, kids will learn how rain builds up in the clouds and what happens when the clouds are full. Different colored “raindrops” are visually stimulating for young children and will keep them engaged. They can also see what happens when colors mix. Help your child use their science skills and have them predict what will happen.
Rainbow Cloud Experiment
Materials
- Glass Jar
- Cups or bowls (one for each color you plan to use)
- Water
- Shaving cream
- Food Coloring
- Spoon
- Eye or medicine dropper
- Paper towels
Instructions
- Use your spoon to mix water and food coloring in different cups to create different colored raindrops.
- Fill the glass jar 3/4 full with plain water.
- Add shaving cream to the top of the water in the jar — roughly 1-2 inches. Be sure the shaving cream covers the entire top of the water.
- Use the eye/medicine dropper to drop different color “raindrops” on top of the shaving cream. Do this part slowly and carefully!
- See how long it takes for the raindrops to come through the “clouds.”
The Science Behind It
The rainbow rain cloud experiment helps to introduce and explain why it rains. In this experiment, the shaving cream slowly absorbs the colored water. Once the shaving cream becomes too full, the colored water drips its way out into the water. Rain clouds do the same thing! As the clouds absorb water and get full, they begin to swell and it starts to rain! Hope you all have fun with this!
Science Friday: Underwater Volcano Experiment
Observing and predicting are two important concepts in your child’s science education. Observing teaches them to use their senses to gather and organize information about the world. Predicting is when they use the information they have observed to make a guess about what will happen. Although science can seem like an intimidating subject for preschoolers, it doesn’t have to be! This underwater volcano experiment is the perfect example. It’s simple, mess-free, attention-grabbing, and best of all – teaches the scientific method. Follow along below!
Underwater Erupting Volcano
Materials
- Large jar
- Small jar (make sure it fits inside the larger jar)
- A small rock
- Hot and cold water
- Food coloring
Instructions
- Pour cold water into the large jar.
- Place the small rock in the small jar. This will help to weigh down the jar and keep it from floating in the larger jar.
- Carefully pour the hot water into the smaller jar and add your food coloring.
- Gently place the smaller jar inside the larger jar and observe what happens!
The Science Behind It
Water is made up of something called molecules. Hot and cold water are made up of the same type of molecules. The only difference is that the molecules in hot water move around much more than the molecules in cold water – kind of like a kid with a lot of energy! Because the hot water molecules move around more, it creates an “underwater eruption” when placed into the jar of cold water.
