Create a safe and simple volcano model that demonstrates a chemical reaction. Use baking soda and vinegar to simulate a volcanic eruption.
Explore the chemistry of surface tension and molecular bonds by adding drops of food colouring to a dish of milk and observing the patterns.
Make slime using common household items like glue and borax. This project introduces the concept of polymers.
Use red cabbage juice as a natural pH indicator. Kids can test different household substances to see if they are acidic or basic.
Create a simple battery using lemons and zinc-coated nails. Learn about the chemical reactions that generate electricity.
Make invisible ink using lemon juice or milk. Write secret messages and reveal them using heat from a light bulb.
Grow crystals from common household solutions, such as salt or sugar water. Explore the process of crystallization.
Layer different liquids of varying densities (like oil, water, and syrup) to create a colourful and educational liquid density tower.
Combine baking soda and vinegar in a sealed plastic baggie to observe a chemical reaction that produces gas, causing the bag to inflate.
Layer liquids of different densities (like honey, dish soap, water, and oil) to create a visually appealing rainbow effect in a clear jar.
