Geology becomes accessible through hands-on exploration. Discuss where rocks come from and how weather changes them over time. Create a rock collection display with handwritten labels.
Physics Fun for Little Ones
Ramp Racing
Build ramps using cardboard or wooden blocks at different angles. Race toy cars down each ramp, measuring which angle makes cars travel fastest or farthest.
This science activity preschool experiment introduces gravity, force, and motion. Children make predictions, test them, and draw conclusions. Change variables like ramp height or car weight for extended learning.
Magnetic Discovery
Provide magnets and a collection of items: paper clips, plastic toys, wooden blocks, metal spoons, and aluminum foil. Children test which items magnets attract and create sorted piles.
Magnetism seems like magic to preschoolers. This hands-on exploration reveals invisible forces at work. Hide metal objects under paper or fabric and let children use magnets to locate them.
Balance Experiments
Create a simple balance using a ruler and a block as a fulcrum. Children place objects on each end, discovering which items weigh more through direct comparison.
Weight and balance concepts emerge through play. This activity science for preschool develops mathematical thinking and estimation skills. Progress to using actual scales for more precise measurements.
Bubble Science
Giant Bubble Solution
Mix six cups of water, one cup of dish soap, and one tablespoon of glycerin or corn syrup. Let the solution rest overnight for best results. Create bubble wands from pipe cleaners or use store-bought options.
Bubble experiments teach surface tension and air properties. Children observe rainbow colors in bubble surfaces and learn why bubbles are always round. Experiment outdoors for less mess.
Bubble Painting
