Curiosity is a powerful force that fuels the minds of young explorers. Science experiments provide an exciting, hands-on way for kids to satisfy their curiosity while learning about the world around them.
These experiments are not only entertaining but also encourage critical thinking, problem-solving, and a love for science.
Note for parents and guardians: All of the experiments in this piece should be carried out with adult supervision. While these experiments are well-suited for early learners, some involve fire, glass, and other potential hazards that we recommend adults handle. Some of these experiments can also get a bit messy, so setting down towels or conducting them outside is also highly recommended.
Grab your lab coat, exercise caution, and let’s embark on a journey of discovery!
Materials needed: Clear glass cup or bottle, carbonated water, and raisins.
- Fill the glass with carbonated water.
- Drop a few raisins into the glass and observe.
The carbon dioxide bubbles in the carbonated water attach to the raisins, causing them to rise to the surface. As the bubbles pop at the top, the raisins sink back down. This back-and-forth motion creates a dancing effect.
Materials needed: A shallow dish, whole milk, food coloring, and dish soap.
- Pour the milk into the shallow dish, filling it about halfway.
- Add drops of different food coloring to the milk.
- Dip a cotton swab into dish soap and touch it to the surface of the milk.
The dish soap reduces the surface tension of the milk, causing the food coloring to spread and create swirling patterns. This experiment showcases the concepts of surface tension and chemical reactions.
Baking Soda and Vinegar Volcano
Materials needed: A small container or volcano model, baking soda, vinegar, dish soap, and food coloring (optional).
- Place the small container or volcano model on a tray or in a bowl.
- Add a tablespoon of baking soda to the container.
- Mix ½ cup of vinegar, 1 tbsp of dish soap, and 1 tbsp of food coloring (if desired) in a separate container.
- Pour the vinegar mixture into the container or volcano model and watch the eruption!
The baking soda (sodium bicarbonate) reacts with the vinegar (acetic acid), producing carbon dioxide gas. The gas bubbles expand and create an eruption, similar to a volcano.
Egg in a Bottle
Materials needed: A hard-boiled egg, a glass bottle with a narrow opening, matches, and a strip of paper.
- Place the glass bottle on the table.
- Peel the hard-boiled egg and set it aside.
- Light your strip of paper with your match.
- Once the strip of paper is burning, carefully but quickly drop it into the bottle.
- Place the egg on top of the bottle.
- Observe the egg being sucked into the bottle.
When the match burns, it consumes oxygen inside the bottle, creating a vacuum. The pressure difference between the inside and outside of the bottle pushes the egg into the bottle to equalize the pressure.
