Here are a few standout quick experiments to try:
Dancing Raisins
A true classic, the dancing raisins experiment requires only a glass of carbonated soda and a few raisins.
What it teaches: This activity demonstrates gas behavior and buoyancy. As carbon dioxide bubbles stick to the raisins, they lift them upward. Once the bubbles pop, the raisins sink only to rise again.
Why it matters: Kids learn about how gases can impact the movement of solids and how bubbles help objects float.
Raising Water
This science experiment uses a shallow dish, water, a candle, and a clear glass to show how air pressure can move water.
How it works: Light the candle in the center of the dish filled with a little water. Then place the glass upside-down over the candle. As the flame uses up the oxygen inside the glass, it extinguishes, and water rises into the cup.
The science behind it: The drop in air pressure inside the glass causes outside pressure to push water in. This is a great way to explore air pressure using common household items.
Water Walking
With just paper towels, three clear cups, and food coloring, this easy science experiment shows how liquids can "walk."
What kids learn: This explores capillary action, where water moves upward through fibers similar to how plants draw water from soil.
