Rainy days can be a drag for preschoolers, but with the right activities, they can be a lot of fun. Science activities are a great way to keep preschoolers engaged and learning, even on a rainy day. Here are some fun science activities that you can do with your preschooler on a rainy day.

Rainbow in a Jar

Rainbows in a jar is a fun way to show your preschooler the basics of light refraction. All you need is a mason jar with a lid, some food coloring, and a piece of white paper. Fill the jar with water, add a few drops of food coloring, and then screw the lid on tightly. Hold the jar up to the light, and then have your preschooler look at the white paper. They will be able to see the rainbow on the paper.

Make a Lava Lamp

Making a lava lamp is a great way to teach your preschooler about density and the different densities of liquids. To make a lava lamp, you will need a clear jar or bottle, vegetable oil, water, food coloring, and Alka-Seltzer. Fill the jar with equal parts of water and vegetable oil. Add a few drops of food coloring and then drop in a piece of Alka-Seltzer. The oil and water will mix, then separate, and the Alka-Seltzer will cause the colors to mix and bubble.

Create a Cloud in a Jar

This is a fun activity that will show your preschooler how clouds form. You will need a mason jar with a lid, some hot water, and some ice cubes. Fill the jar with hot water, screw the lid on tightly, and then add the ice cubes. As the air in the jar cools, the water will condense and form a cloud in the jar. Your preschooler will be able to see how the cloud is formed and how it dissipates.

Make a Tornado in a Bottle

This is an easy and fun activity that will show your preschooler how a tornado is formed. You will need two plastic bottles, some water, and some food coloring. Fill one bottle with water and add a few drops of food coloring. Then fill the other bottle with water, screw the lids on tightly, and then turn the bottles upside down and put them into each other. Swirl the bottles around and your preschooler will be able to see the tornado form in the bottle.

Make a Volcano

Making a volcano is a great way to show your preschooler the basics of chemical reactions. All you need is a large plastic bottle, some baking soda, vinegar, and food coloring. Fill the bottle with baking soda and then add a few drops of food coloring. Add some vinegar to the baking soda and watch as the volcano erupts. Your preschooler will be amazed at the chemical reaction and what it can do.

Make a Rainbow

Making a rainbow is a great way to show your preschooler how light refraction works. All you need is some water, a shallow bowl, and a white piece of paper. Fill the bowl with water and then place it in front of the white paper. Shine a flashlight on the water and your preschooler will be able to see a rainbow on the paper.

Make a Water Wheel

This activity is a great way to show your preschooler the basics of physics. You will need a shallow bowl, a few paper cups, and some water. Cut the paper cups in half and then place them in the bowl. Fill the bowl with water and then have your preschooler spin the cups. The cups will spin and cause the water to move, showing your preschooler the basics of how a wheel works.

Make a Cloud in a Bag

This is a fun and easy activity that will show your preschooler how clouds form. You will need a clear bag, some water, and some ice cubes. Fill the bag with water and then add the ice cubes. As the air in the bag cools, the water will condense and form a cloud in the bag. Your preschooler will be able to see how the cloud is formed and how it dissipates.

Make a Rain Gauge

Making a rain gauge is a fun way to show your preschooler about measuring precipitation. You will need a bottle, a ruler, and some tape. Measure the amount of water in the bottle and then mark the level with a ruler. Put a piece of tape on the bottle and then place it outside. Have your preschooler measure the amount of rain that falls in the bottle and then record the results.

Rainy days can be a lot of fun with the right activities. With these fun science activities, your preschooler can learn and have fun on a rainy day.
