National Science Week – Bolwarra
There has been some exciting experiments happening at Bolwarra for National Science Week! 👨🔬👩🔬
Today, the Platypus children engaged in a chemical reaction experiment using bicarb soda, vinegar and food dye. What happened in this experiment? Well, as the vinegar and the bicarb mix they have a chemical reaction that release a carbon dioxide gas, this creates the bubbles and a gas which we can smell. We were also able to investigate with colour change as the dyes combine! 💥 The children experimented with the amounts of vinegar and bicarb they used to create the chemical reaction, as well as the amount of different colours they could mix to observe the changes that were happening. 🤩✨
🌟Here’s how you can do this at home too! 🌟
– Bicarb soda
– Food colouring
– Test tubes and rack (but you could simply use cups!)
– Cup for vinegar
– Pipettes or syringes for vinegar
– Bowl for bicarb
1. Prepare the ingedients – Add vinegar to the cup and a few drops of food colouring. Add bicarb to the bowl and a few drops of food colouring.
2. Using the pipette, suck up the coloured vinegar and squeeze out into the test tube.
3. Using a spoon, spoon some bicarb into the test tube to mix with the vinegar
4. Wait for the chemical reaction!
5. Experiment with different amounts of vinegar, bicarb soda and food colouring.
