Why do peeps expand

Well, there is only one way to find out. Design a Peeps science experiment! Weigh your glass bowl. If your scale has a tare feature, use it now. If not, record the weight of the bowl. Next, add a Peep to the bowl and record the weight of the Peep. If you do not have a tare feature on your scale, you will have to subtract the weight of the bowl from the weight of the bowl and the Peep to find the weight of the Peep alone.

Place the Peep and the bowl in the microwave. Heat for 30 seconds. Immediately after the microwave shuts off, take the bowl and Peep out of the microwave and weigh it. Record the weight of the Peep. Again, subtract the weight of the bowl if you did not use the tare feature. Continue this procedure with new Peeps each time increasing the time by 10 seconds until you have reached 60 seconds.

Each time you repeat the experiment, it is called a trial. Record the before and after weights, along with the time for each trial. When all the trials are completed. Subtract the ending weights of each trial from the beginning weights.

This is the mass or weight lost in each trial. Graph the amounts of weight lost against the time each Peep was heated. What does the graph look like? Chapter Leadership Days. EPC Committee.

The hot water warms the sugar, which softens a little. The hot water also warms the air bubbles. When you warm air in a closed container, the gas molecules move around faster and push harder against the walls of the container. As the air in the bubbles warms up, the air molecules bounce around faster and faster and push harder against the bubble walls.

Since the sugar walls are warm and soft, the bubbles expand, and the marshmallow puffs up. If it puffs up too much, some air bubbles burst, and the marshmallow deflates like a popped balloon. When you take the marshmallow out of the microwave and it cools off, the bubbles shrink and the sugar hardens again. If you cook your marshmallow for too long, it turns brown or black inside.

That happens when the sugar gets so hot that it starts to burn. See caramelizing sugar. As the marshmallow puffs up, the face will get bigger and bigger. What Do I Need?
