Volcano eruption!




Room 2 and Room 4 put on their green hats (creative thinking) and became scientists!

We made our own volcano and created a chemical reaction (chemical change) by adding food colouring, liquid detergent, baking soda, vinegar and water. After mixing the baking soda and vinegar we watched the chemical reaction, green lava fizzed and bubbled out the top!!

We are interested in finding out why mixing baking soda and vinegar creates a chemical reaction.

We wrote explanations about what happened to the baking soda and vinegar:
When the vinegar mixes with the baking soda a gas is formed called carbon dioxide and the bubbles push the "lava" out the volcano.
