(I know she's eating it, but she's cute!
She's mine and she's the baby of the class this year.)
Basically, you take an apple and split it in half. We used Marshmallow creme to spread over the top of the apple and then you put mini-marshmallows on top. We've done this before but with peanut butter. Which in all honesty, works much better. The creme kinda melted, but the kids who were really meticulous and put marshmallows all over the igloo, didn't have any problems.
It's a sticky project, but well worth doing.
Here are some great Igloo worksheets to use with this project.
