The children and I have done a few activities with ice:
My son saw the Ice Boat idea on Play School and we recreated it. Such a simple yet novel activity.
Small freezer proof plastic containers (plastic bowls works well)
Food Colouring (optional)
Large underbed storage container (or other plastic container) — alfoil if wanting to slide the boats rather than float them.
What to do
1. Use a piece of blu-tack to stick a straw in the middle of the container.
2. Fill the container with water and add food colouring (if desired)
3. Freeze until solid (approx 8 hours)
4. Cut a sail triangle shape out of paper. I used coloured paper but plain paper coloured with pencil or texta works well too. Using scissors, puncture two holes and weave on to straw.
5. To aid in removing the ice boat from the container, sit in the sink filled with a little warm water for about 30 seconds.
6. Fill a large container with water (I set it up outside) and place the boats in. Sometimes fine cracks appear but the boat will hold well together for about 20-30 minutes depending on how big the piece of ice is and how warm the day. Another idea is play with the boats without water. Set up some alfoil moulded ramps either inside the box or on a slight incline somewhere.
It’s late and my son is asleep now, but tomorrow, I will show him what an real-life ice boats look like. They are a like a sail boat but with skate-like blade to aid in gliding on ice. Because that’s cool (pun intended).
