Simple science experiments

Balloon Rocket: Create a mini rocket using a balloon, a straw, and a string, and watch it race along a string when the balloon is released.

Homemade Volcano: Build a model volcano out of clay or paper mache, add baking soda and vinegar to create a volcanic eruption with "lava."

Rainbow in a Jar: Layer different liquids in a clear glass to make a colorful rainbow, showing how substances with different densities can stack.

Lemon Battery: Use a lemon to generate a small electric current and power an LED, demonstrating the basics of electricity generation.

Walking Water: Witness capillary action in action by watching colored water travel through paper towels from one glass to another.

Invisible Ink: Write secret messages with lemon juice and reveal them when the paper is gently heated, showing the concept of chemical reactions.

Dancing Raisins: Drop raisins into a glass of carbonated soda to see them bounce and move due to the release of gas bubbles.

Static Electricity Butterfly: Create static electricity by rubbing a balloon on hair and use it to make lightweight objects "stick" to the balloon.

Gummy Bear Osmosis: Observe how gummy bears change in size when placed in water and saltwater, illustrating osmosis.

Magnetic Maze: Guide a metal object through a maze using a magnet beneath the maze, demonstrating magnetic forces.

Skittles Rainbow: Arrange Skittles in a circle, add water, and watch as the colors dissolve and create a rainbow effect.

Baking Soda and Vinegar Rockets: Combine baking soda and vinegar in a film canister to create a small explosion that launches the canister into the air.

Ice and Salt Experiment: Sprinkle salt on an ice cube to observe how it melts the ice faster due to a lower freezing point.

Density Tower: Layer liquids of different densities to create a colorful density tower, showcasing the concept of buoyancy.

Exploding Bag: Mix baking soda and vinegar in a sealed plastic bag to create a chemical reaction that inflates and eventually bursts the bag.

Milk Art: Drop food coloring into milk, then add dish soap to create swirling patterns due to surface tension.

Egg in a Bottle: Place a hard-boiled egg on the mouth of a bottle and heat the bottle to create a vacuum that sucks the egg inside.

Rain Gauge: Set up a simple rain gauge to measure and track rainfall over time, helping kids understand weather data collection.

Potato Battery: Use a potato to create a simple battery and power a small electronic device.

Homemade Slime: Create various types of slime, each with its own unique properties and textures, as an introduction to non-Newtonian fluids and polymer chemistry.
