Rotten Apple Science Experiment

Food goes rotten if you leave it long enough.
You can slow down the rotting process though and we tried to do this with an apple.

 

 

You Need:

 

a fresh apple

4 plastic cups

knife (to cut the apple)

table salt

epsom salts

baking soda

spoon

 

Cut the apple into 4 segments and place one segment into each cup.

We labelled our cups with a black marker and recorded what substance we put into what number cup. You need to cover the apple with the substance.

 

Cup 1 – table salt

Cup 2 – epsom salts

Cup 3 – baking soda

Cup 4 – nothing

 

We left them in a cool place for a week and then we came back and compared them.

 

Cup one with the table salt looked to be the best preserved. Salt draws the moisture out of food. This means that the micro-organisms that cause decay cannot thrive.

 

The baking side discolours the apple. This was our worse decayed apple segment.
