Dissolving Peeps Science Experiment
I don’t know about you, but when I think of Easter candy, I almost always think of Peeps! You know–those marshmallow chicks in all kinds of spring colors. I don’t actually like to eat Peeps (even though my husband does. Yuck! But that’s a whole different story…), but they’re great for science experiments! If you have Peeps to spare this Easter, then you probably already have everything else you need to conduct this easy science experiment!
6 cups water
1/2 cup sugar (divided)
1/2 cup salt (divided)
6 marshmallow Peeps
Place 1 cup of water into three different cups. Into one cup, add ¼ cup sugar, stirring until it is dissolved. Into the second cup, add ¼ cup salt, stirring until dissolved.
Heat the remaining 3 cups of water until hot.
Place 1 cup of hot water into three different cups. Into one cup, add ¼ cup sugar, stirring until it is dissolved. Into the second cup, add ¼ cup salt, stirring until dissolved.
Place one marshmallow peep into each cup of water. Set a timer for 2 minutes.
When the timer goes off, check the marshmallow Peeps and make note of which have changed. Use the printable form (link below) to record the time and the changes you observe.
Continue checking the marshmallow Peeps every 2 to 5 minutes, making note of the changes on the printable form.
Discuss which liquids caused the marshmallow Peeps to dissolve faster/slower and why.
