- What materials will you use to make your iceberg? Where will you freeze it?
- How will you mark the water level of your container to see what happens?
- How will you melt your iceberg?
- Make your own iceberg by freezing water in an ice cube tray (for mini icebergs) or a larger container.
- Place them in a container of water. How do they float?
- Try different ways of melting your iceberg (covering it with a towel, leaving it in the sun, putting it in the fridge, mixing sand into the ice, etc.).
- What makes it melt the fastest? What happens to the water in the container when the iceberg melts?
- What role do icebergs play in our environment?
- How can melting icebergs affect our planet?
- What can we do to help stop icebergs from melting?
Keep it Simple
- Explore the impact of Arctic ice sheets in regulating water levels. Fill a container partway with water, then draw a line at the water level. Freeze the container; is the top of the ice higher or lower than the water line? Why? How is this connected to global warming resulting in higher sea levels?
Take it Further
- Explore dirty icebergs and see if they might warm the Earth at an even faster rate. How might this affect climate change? What can you do to help minimize the negative effects?
