Today, we used it as an introduction to the concepts: frozen & melting - which the kids have had lots of experience with lately -- with all the wintery mixed-up weather that we've been having!
On the back, there was an activity where the kids were supposed to identify which items were 'frozen' and which items were 'melting.'
They had so much trouble showing that they understood the difference between the two, that we just had to do our own experiment to better understand what frozen & melting really meant!
We went outside & collected bags of snow. Once back inside, the kids came up with places to put the bags of snow - after some prodding & suggestions they came up with the fridge, freezer, next the heater & on the window.
We checked on the baggies several times over the next 2-3 hours & the kids were very excited to find that some of their snow had turned into water - it had melted. We took pictures of our observations to make into a book...
We ended out the day by reviewing the pictures that we took, discussing our observations & creating a little book about the melting snow!
by Ezra Jack Keats - and the kids knew exactly what was going to happen to the snowball that Peter put into his pocket ... it MELTED! 
Hopefully tomorrow, when I ask them about 'melting,' they remember our experiment and can easily differentiate between 'melting' & 'frozen.'
