With this experiment, we intend to see if fizzy drinks are good for our health or not. For this experiment you will need:
*Different fizzy drinks
*Other types of drinks you want to try with
*Plastic cups
*Post-it note to label the drinks
*Tape
*Dirty coins
*A worksheet to record your hypothesis and the results of your experiment
Step 1: Pour the drinks on the plastic cups and take a picture with the coins next to them for the before and after comparison.
Step 2: Formulate the hypothesis. On the first part of the worksheet write what
you think is going to happen to the dirty coins with the drinks you are
using.
Step 3: Wait for a day or two and take out the coins. Have some paper or wipies around to clean your hands well after, specialy if you had used vinager or milk like us!
Step 4: Now, write the changes (or not) that you see in the coins after being in the drinks for a couple of days.
