Winter science for kids: Snowman in a bag

If you need an easy way to bring snowman science into the classroom – this will do the trick.

Our snow has melted but chances are it will come back again very soon. But if the snow returns, we will be ready for some fun and simple snowman in a bag science…

What to do!

This process is similar to our snowman in a bottle but if you didn’t have a bottle on hand, then gather up a baggie, some buttons, a snowman nose, and some snow and you are all set to go…

Place a couple of large spoon fulls of snow is all you need in the bag and then lay the bag flat.  Press and pack the snow so it stays flat and then arrange your button eyes and nose on the snow to make a snowman face.  Press the buttons and nose firmly into the snow…

Tape the snowman in a bag to a window so it can get some sunlight and let the melting begin…

How it works!

Here’s what my snowman looked like after about 30 minutes…

And after about 1 hour…

After about 1 hour 30 minutes…

And about 2 hours later…


Questions to ask your students!

A very simple way to explore the melting of snow. Did you notice that bag seems much less full with the snow melted than before? And did you notice that the nose floats but the buttons sink?  And did you notice that snowman moved down the bag as it melted?  And did you notice that all that is left of the snowman is a bag of water?

    Love the Snowman in a Bag idea. I’m going to draw a line on the bag with black permanent marker at the top of the snowman’s head and have kids compare that with where the water line ends up. Kids could “measure” the difference, compare and discover something about density!

    What an adorable way to investigate melting snow. I love your observation sheet for the kids to use. Thanks again for another super (and easy!) idea! Renee

    I wish we had snow around here to do this! it’s 11 degrees out in NJ, but no snow! We had some back in December and a little over break, but by morning it’s always gone.

    This is such a great winter activity idea! Since we don’t get snow where we live I’m thinking we might try it with snow dough.

    my pre-k class made the puffy paint snowman in a box. It was fantastic, they really enjoyed the process, especially the decorating part. We also did the Snowman in a bag experiment, the recording sheet was great. We have been alot of activities around snow and melting that this really summed up our unit. The painting of the snow was one of the activities that they loved the best and they are still talking about it.
    I love your ideas , thanks for sharing
