Candy Rainbow: Easy Science Experiment for Preschoolers

Candy Rainbow: Easy Science Experiment for Preschoolers

This easy science experiment will engage and delight your preschooler as the colors from the candy swirl around the plate. Your child will notice the pattern the colors make in the water and even how the colors mix to make new colors. In addition to having a ton of fun, your child will also be working on a number of different developmental skills, like 

Fine Motor Skills: As your child picks up each candy they are helping to develop the fine motor skills that will help them do important things later like grip a pencil.

Pre-Math Skills: Using different colored candies and arranging them on the plate will help your child build pre-math skills like recognizing patterns and sorting objects.

Critical thinking: Be sure to ask your child what they think will happen before the water is added and why they think the water makes the colors swirl to help them start thinking critically about the world around them. 

Now that you know how educational this project is, let’s get to the fun!
