This fun, child-friendly science experiment is a great sensory activity for toddlers and young preschoolers. For the experiment, you will need: baking soda, vinegar, dish soap, green food coloring, a shallow bin or container, squeeze bottles, and a few small pumpkins. Simply place the pumpkins and small drops of dish soap in the container, and add small drops of food coloring to the dish soap. Cover the tray with the baking soda until you can’t see the drops anymore. Finally, fill the squeeze bottles halfway with vinegar, and set all of the items out for children to explore.
Invite children to take turns using the bottles to squirt vinegar into the container and observe the fizzy reaction! They will love watching the green foam fizz around the pumpkins. This activity is a great introduction to science and chemistry, while also encouraging children to strengthen fine motor skills in their hands as they squeeze the bottles.
