Join Jonathan every day at 9:20am on QC Morning for a new science lesson!
Hey parents! Looking for a substitute for your “science class”?
We recommend J-Stace the Science Ace.
Do you have leftover Peeps from this weekend that you don’t plan on eating? You could use them in this experiment to learn how heat interacts with pockets of air trapped inside of the famous… or infamous… Easter treat.
Ingredients & Supplies:
- Microwavable plate
- Place Peeps on a microwavable plate.
- Place the plate of Peeps in the microwave and microwave for one minute.
- They should start to see the Peeps puff up after about 20 seconds.
- Remove the Peeps from the microwave and make your observations.
- Note that the Peeps will begin to deflate/lose their puffiness fairly quickly.
The Science Behind the Experiment
Peeps are marshmallow candy mostly made up of sugar and water surrounded by air pockets. As they are microwaved, the water in the Peeps heats up, softens the sugar and warms the air molecule, causing them to push against the soften sides and puff up the Peeps. The heat from the microwave causing the Peeps to expand through the process known as thermal expansion.
Today’s vocabulary word is: Thermal expansion – is the tendency of matter to change its shape, area, and volume in response to a change in temperature.
