Even though it's just the end of January, this has seemed like a very long winter. The temperatures in our area and around the country have been arctic cold. It's dangerously cold for any sort of outside activities, including trips to the playground.

Last week, we were home for five straight days due to a snow storm. By the third day, my kids were done with staring at the same walls. In an effort to combat cabin fever, I hopped on Pinterest, found a few simple weather science experiments, and hunted for materials around the house.

The end result kept us busy for a few mornings with these fun activities.

  • Water
  • Borax
  • Glass jar with large opening
  • String or yarn
  • Pencil
  • Pipe cleaners
  • Scissors


  1. Create a snowflake by cutting pipe cleaners into pieces and twisting.
  2. Tie one end of the string to the middle of a pencil and tie the other end of the to the snowflake.
  3. Suspend the snowflake into your glass jar by laying the pencil across the top.
  4. Fill a pan with just enough water to fill your jar and bring to a boil. Once boiling, add 1 tablespoon of Borax to the water at a time, just until it no longer dissolves.
  5. Pour the Borax mixture into the glass jar and suspend the snowflake in it.
  6. Let the jar sit overnight.
  7. The next day, your kids will be amazed by the crystals on the side of the jar and on the snowflakes.

Salt Icicles



  • Salt in a salt shaker
  • Elmer's Glue
  • Construction paper
  • Food coloring (optional)
  • Cookie sheet


  1. Lay construction paper in a cookie sheet (to contain the mess).
  2. Have your child spread Elmer's Glue along the top of the paper. Lift up the paper and turn it up so the glue drips down like an icicle.
  3. Show your child how to sprinkle the salt on the glue and then tilt the paper up so it spreads along the glue forming the icicles.
  4. Allow to dry.

Optional: Using an eye dropper, have your child drip different colors into the salt and watch the color spread.

Melting Icebergs

Source: Stir the Wonder


  • Small plastic toys (preferably arctic animals)
  • Plastic container
  • Plastic ziploc bags
  • Food coloring and/or glitter
  • Water
  • Coarse sea salt
  • Sugar


  1. Place zip lock bag into a container so it sits in the container securely.
  2. Place plastic animals in the zip lock bag and fill about 3/4 of the bag with water.
  3. Help your child squirt food coloring into the bag. You can also put glitter into the bag as a fun effect.
  4. Carefully lift the bag of water out of the container and fill remainder of the bag with water.
  5. Close the zip lock bag and place in the freezer until completely frozen.
  6. Once frozen, open the bag and pull it away from the solid chunk of ice.
  7. Help your child experiment with the sea salt, sugar, and warm water to determine what will melt the iceberg the quickest in order to free the animal.

Extension: While your child is playing with the ice, talk about the difference between solid and liquid. Compare the difference the salt vs. the sugar makes on the ice in terms of helping it dissolve.

  • Bowl of snow
  • Thermometer


  1. Fill a bowl with snow.
  2. Insert the thermometer into the snow and teach your child how to take a temperature reading.
  3. Bring the snow inside and have your child play with it. Once it all melts, take the temperature of the water and compare it to your previous reading.
