ice final

Sneak in some science with these fun ice towers. These are great for a hot summer day (using your freezer) or a cold winter day when you can simply place them outside to freeze!

Materials:

  • food coloring or liquid watercolor paints
  • water
  • salt (optional)
  • bowls of various shapes and sizes (plastic containers work, too)

Instructions

  1. ice4Fill the bowls with water.

  2. Add color by dropping in food coloring or paint. Let your little scientists experiment with mixing colors and watching the mesmerizing patterns.

  3. ice5When you're all done playing (or have run out of bowls), carefully take them outside to freeze or stick them in the freezer. We left ours outside overnight. NOTE: If the ice is stuck, it will come out easily after you run a bit of hot water over the outside of the container.

  4. Set a large towel on the table to catch the drips and/or paint from your ice sculptures.ice 6

  5. Take it further: If you're playing outside or if your ice is not watery and melted on the outside, you can stick two pieces of ice together by adding a touch of salt—but it won't work if the outside of the ice isn't dry. (The salt causes the surface of the ice to melt until diluted, then when you place ice on top of it, it causes the water to ice8freeze again.)

Happy playing!

    A few bullet points on the science concepts that could be communicated. A Parents as Teacher’s Tip Sheet would be very helpful. Not a worksheet for the kids, but some guidance about how to talk about “freezing” or why the salt helps two pieces bind – sure technically it is a chemical reaction but what does that mean to a six year old?
