We began by talking about our problem.
Then we formulated a question.
And a hypothesis.
Next, we each made a prediction.
Then we conducted our experiment.
I prepped by dividing paper plates into 4 parts and adding the names of the liquids.
Then we dipped the apple slices into either soda, milk, lemon juice, or water and placed them on the plates.
Then came the hard part for my Kinders ... waiting!
We waited an hour and then observed the apple slices.
The differences between all of the slices was very subtle, but we did find that dipping an apple slice in lemon juice slowed down the browning process.
We recorded our results on this sheet.
Here is our display board, all ready for the Science Fair!
