Our Neighbourhood's Experiment

The Effect of Lemon Juice on Banana

On Monday Mark made the statement 'lemon juice stops banana's from going brown'. As a neighbourhood we decided that we should test this idea. Below is our experiment.

Question: Does the banana go brown when lemon juice has been poured on it?

We need used:
1 Banana (cut in thirds)
1 Lemon
1 Knife
2 Plates
2 Signs (Banana with lemon/Banana without Lemon)

What we did:
1. Mary cut the banana into 3 pieces, placed one piece on each piece and gave the third piece to Sapphire.
2. Mary cut the lemon in half
3. Zoe squeezed the lemon on one piece of the banana
4. Olivia wrote the 2 signs
5. The plates of bananas and the correct signs were placed in the Observing Area
6. On Wednesday morning we looked at the bananas to see if the bananas had gone brown

Result:
The banana with lemon juice did not go brown, but the banana without lemon juice was brown.
Sapphire had eaten some of her banana and what was left was brown.
