We did an experiment similar to this peeps experiment with pennies for JDaniel’s school science fair project. We used the same liquids and followed almost the same steps. You may decide you want to try liquids different than the ones we did. Our liquids with the exception of the soda all had a little bit of acid in them. We knew they would disolve some of the sugar off the Peeps!
Peeps Experiment Printables
A set of Peep ScienceEffects of Liquids on Peeps was created for you to use. One of them lists the supplies needed to conduct the Peeps experiment. It also has a place to write your predictions and an area to write the results.
The second and third printable look just at the results. One of them has the liquids we used listed on it. The second has the area for the liquids left blank. You can have your children write in the liquids they select on each blank. You will notice that both printables have space for your children to write in how each Peep looks, smells and feels. You could have your children explore how they taste and sound, but we decided not to do that.
Conducting the Peeps Experiment
After deciding on the liquids you want to use, you will need to place them in small containers. (We used empty applesauce containers). Then you will need to place a Peep in each container.
Next, you will need to leave the Peep in the liquid for twenty-four hours. It may be hard for your children to leave the Peeps in the liquids. My son kept wanting to turn them over.
At the end of the 24 hours, your children will need to inspect the Peeps. They will need to share and record the results. If your children are too little to record results, you can have them share what the see, smell and feel with your orally.
Some of Our Results
- The blue coating came off the backs of all the Peeps.
- The lemon juice turned blue
- The soda got gummy. It created a gummy slime on the back of the Peep.
- The Peep in the vinegar puffed up a little and was slimy to touch.
- The lemon juice Peep puffed up a little and it was smooth.
- The Peep in ketchup didn’t change much. It did smell like tomatoes.
