10 Easy Science Projects for Home Learning

4. DIY Lava Lamp

Create a mesmerizing lava lamp at home using water, oil, food coloring, and effervescent tablets (like Alka-Seltzer). Fill a clear container mostly with oil, add some water, and a few drops of food coloring. When you drop in the tablet, bubbles of colored water rise and fall through the oil, mimicking the effect of a commercial lava lamp.

This experiment demonstrates immiscibility (how oil and water don’t mix) and buoyancy, as gas bubbles carry the colored water up before they burst and sink. For detailed instructions, visit the Science Buddies Lava Lamp Project.

5. Static Electricity Butterfly

Bring a tissue paper butterfly to life using the power of static electricity! Cut out a butterfly shape from tissue paper and lay it on a flat surface. Inflate a balloon and rub it vigorously against your hair or a wool cloth to build up static charge.

When you hold the charged balloon near the butterfly, it will flutter and move, thanks to electron transfer and friction. This experiment introduces the science of static electricity, much like the classic trick of making hair stand on end. Explore more with the PBS Kids Static Butterfly activity.

6. Homemade Water Filter

Build a simple water filter using a plastic bottle, sand, gravel, and activated charcoal. Cut the bottle in half and layer the materials inside, starting with charcoal, then sand, and finally gravel. Pour dirty water through the filter and observe how each layer removes different types of impurities.

This hands-on project demonstrates the principles of mechanical and chemical filtration, similar to processes used in municipal water treatment plants. It’s a practical way to understand how clean drinking water is produced around the world. For further exploration, visit National Geographic Water Filtration.

7. Dancing Raisins

Watch raisins “dance” by dropping them into a glass of clear soda, such as club soda or lemon-lime soda. The carbon dioxide bubbles in the soda attach to the wrinkled surface of the raisins, increasing their buoyancy and causing them to float to the top.

When the bubbles pop, the raisins sink again, repeating the cycle. This experiment is a fun way to illustrate buoyancy and the effects of gas bubbles in liquids. Try testing other small objects to see if they’ll dance too! Learn more at Scientific American’s Dancing Raisins.

8. Walking Water

Explore capillary action by connecting cups of colored water with paper towels. Place paper towels so they bridge between cups, and watch as the water “walks” up and over into empty or differently colored cups, creating vibrant color mixing.

This process mimics how plants transport water from roots to leaves, moving liquid against gravity through tiny tubes. You can compare this with the celery-coloring experiment, where colored water moves through celery stalks. Both activities visually demonstrate water movement in nature.

9. Egg in a Bottle

Watch air pressure in action by placing a peeled, hard-boiled egg on the mouth of a glass bottle. Light a small piece of paper, drop it inside, and quickly set the egg on top. As the flame uses up the oxygen, the air pressure inside drops, and the higher outside pressure pushes the egg into the bottle.

This dramatic demonstration reveals the power of atmospheric pressure. It can be compared with the classic crushed can experiment, which also uses pressure differences to create surprising results. For full instructions, see the Exploratorium Egg in a Bottle guide.

10. Solar Oven S’mores

Create a simple solar oven using a pizza box, aluminum foil, plastic wrap, and black paper to harness the sun’s energy and make delicious s’mores. By reflecting and absorbing sunlight, the oven heats up, melting chocolate and marshmallows without any electricity or fire.

This experiment teaches about solar energy, heat absorption, and the greenhouse effect in an engaging, tasty way. You can compare this method to other solar cookers, such as parabolic reflectors or solar panels. For step-by-step instructions, visit NASA’s Solar Oven Activity.
