1. Make Ice Cream

Use salt, ice, cream, sugar, and vanilla to observe phase changes and make a tasty treat. Vary ingredients to see impacts on texture.

2. Model Molecules

Build 3D models of simple molecules like water or methane using gumdrops and toothpicks. Learn molecular geometry and bonding.

3. Test Cereal Iron

Use spectroscopy methods to quantify iron content in breakfast cereals. Develop lab skills and analytical techniques.

4. Test Household pH

Measure and compare the pH of cleaners, sodas, etc with the cabbage juice indicator. Explore acids, bases, and pH scales.

5. Lava Lamps

Simulate flowing lava in homemade lamps. Mix oil, water, and fizzy tablets to see density differences.

6. Elephant Toothpaste

Catalyze decomposition of hydrogen peroxide with soap and potassium iodide. Observe rapid, dramatic foam explosion.

7. Baking Chemistry

Vary baking ingredients like sugar, powder, and eggs in recipes to see chemical effects on taste, texture, and rise.

8. Strawberry DNA

Isolate and observe DNA from strawberries using dish soap, salt, and alcohol extraction methods.

9. Make Batteries

Generate electricity in lemon or potato batteries through redox reactions. Power clocks or lights.

10. Neutralizing Antacids

See how antacids like Tums can neutralize acid by measuring pH before and after addition.

11. Leaf Chromatography

Separate plant pigments using chromatography. Compare extracted compounds.

12. Grow Crystals

Grow various crystal shapes and sizes by slowly evaporating saturated salt solutions.

13. Model Volcano

Build a model volcano and simulate an eruption using a baking soda and vinegar reaction.

14. Milk Proteins and pH

Test the pH of milk varieties. Observe the impacts of protein content on acid coagulation reactions.

15. Invisible Ink

Write hidden messages using lemon juice, baking soda, and vinegar. Develop by heating later.

Conclusion

The chemistry projects described here are just a sampling of the hundreds of hands-on investigations students can undertake. The key is finding an experiment that aligns with the concepts being taught in class. Safety should always come first, too — adult supervision is a must, especially when heating or using potentially hazardous chemicals. While things don’t always go according to plan, troubleshooting unexpected results is part of the scientific process! The projects on this list provide a creative way for students to learn core chemistry topics by doing real experiments and analyses. Chemistry comes alive when you can see chemical reactions in action and make first-hand observations. So, try out some of these fun chemistry projects to engage students of all ages in the wonders of science!
