The rainy autumn season has begun around the world, children are also very interested in the change of weather in autumn, For children who have not seen clouds and rain, don’t understand the formation and density of clouds and rain. Alpha science classroom will do a special experiment to make a rain cloud in a jar is a great way to help kids visualize how raindrops form. It’s an easy science experiment for kids that you probably already have the supplies in your kitchen.

Alpha science classroom：How to make rain clouds in a jar
1.Add 3 spoons of shaving cream on top of a jar of water. Talk to the kids how the water droplets rise in the air and condense on dust particles. A huge group of them together is a cloud, in this demo, the shaving cream is the cloud.
2.Add drops of liquid watercolor or food color. Once it gets saturated enough it will start to rain. Just like in a real cloud, once there are enough water droplets gravity pulls them back down to Earth as rain.
We ended up trying both liquid watercolors and food coloring. Each has a different thickness so has a little bit of a different effect. The food coloring ran through quicker and the liquid watercolors had more of a rain effect.
Both give kids the cloud visual so use whatever you have on hand, but if you have both it’s fun to experiment to see the difference!
Alpha science classroom is a fun activity in which children explore the mysteries together using the density of various materials. Even if it looks like a drop of water, this is an accurate model of how water condenses into clouds and falls with the rain. How can this activity be used to explore what happens when different kinds of materials are layered on or on top of other layers? Children can find more interesting children's scientific experiment projects in the world of Children's puzzle science Toys in Alpha Science Toys, explore more interesting scientific knowledge and principles, complete the future children's scientific experiment activities at home, and become the most powerful little scientists.
