WALT: observe and report on the chemical reaction that occur when combining substances altogether.
Today we used test tubes and beakers. We were investigating chemical reactions between liquid and materials. The materials we used were: Citric Acid, Tartaric Acid, Baking Soda and Raro. And the liquids we used were: Lemon Juice and Vinegar.
William and I’s reaction diverged across the experiment:
- Lemon + Raro
Hypothesize prediction - It will take time to react.
What happened?
There was no chemical reaction but it did have a change of colour
- Tartaric Acid + Vinegar
Hypothesize prediction - Might have a chemical reaction immediately.
What happened?
It did not have a chemical reaction.
- Citric Acid + Vinegar
Hypothesize prediction - Might not have a chemical reaction.
What happened?
It had no chemical reaction
- Baking soda + Vinegar
Hypothesize prediction - chemical reaction might take time.
What happened?
The chemical reaction happened straight away.
Our science experiment took us from morning tea to the end of our school day. It was a interesting experiment because of our results.
