Winter STEM Family Night

It was too cold to go anywhere today, so we came up with some fun activities to do together at home. We decided to make our theme "Winter STEM". I wrote up 8 challenge cards and we took turns picking a number to find out which challenge we would do next. We broke up in boys vs. girls teams to do each challenge.
(We have a makerspace area in our home, so we used a lot of the supplies I have in there: https://workingmomwonders.blogspot.com/search?q=makerspace)

Challenge #1: Draw a maze that will get the snowball to the snowman. I hot glued a magnet to a little Styrofoam ball and hot glued another magnet to a large Popsicle stick. We each drew a maze on a piece of paper and tried each other's mazes out.

Challenge #2: Build a sled and a ramp using any materials in the makerspace. We came up with very different designs for this!

Challenge #3: Build an igloo using any materials in the makerspace. 

Challenge #4: Make a geoboard snowflake

Challenge #5: Make a snowman using toothpicks and marshmallows. 

Challenge #6: Guess how much water is actually in snow. (We filled this bottle with snow and drew our guesses on the bottle. We let it melt while we did some of the other challenges.) 

Challenge #7: Make an exploding snowman (Draw a snowman on a ziplock baggie that has baking soda inside. Add vinegar and seal immediately. The bag will fill with pressure and pop.) 

Challenge #8: Design a snowflake--we had hole punches, paper, and scissors to create our best snowflake design.
