Melting snow experiment
How much water results from the melting of 2 litres of snow?
Before you try this experiment out try to guess what the amount of water will be.
Collect enough snow to fill a two litre container.
Then they allow the snow to melt by leaving it in a warm place. When all of the snow has melted, mark the water level in the container.
They then compare the amount of water in the container to the amount of snow that was melted.
Evaluate your predictions, then summarise your findings in a notebook.

Slipping and sliding experiments.
Slipping and sliding can be fun when your riding a toboggan down hill or skating on ice. The toboggan and the skates glide over the icy surface. This is a low friction activity, which means that the two surfaces in contact slide easily over each other.
Which is a low friction activity?
A. Dry soap and dry hands
B. Wet soap and wet hands.
Soap and water.
- Pick up a dry bar of soap and rub it gently over the palm of your hand.
- Now try it with wet ha nds and wet soap.
Result:What do you notice?
Which is the low friction activity?
However, slipping and sliding isn't always fun. Driving a car when there is snow or ice on the road can be very dangerous. If there is low friction between a car tyre and an icy road, the car may skid out of control and crash. So often when there is snow or ice around the roads are gritted with sand and salt.
Why does the road grit have salt in it?
- 3 glasses 3. Some salt
- Ice cubes 4. Some sand.
- Place ice cubes in all three glasses A,B, and C.
- Add some salt to glass B.
- Add salt and sand to glass C.
Result: What do you notice about the ice in glass B? Compare it to glass A.
Is it easier to pick up the ice cubes in glass A, B, or C?
Other ideas when it's verrrry cold outside...
Blow bubbles outside,
They won't pop when it's -30 to -40 degrees Fahrenheit below zero outside. Write a poem about the snow and cold.
What does the cold feel like? Smell like? Sound like? Write your observations down in the form of a poem. See what happens to something plastic in the cold.
Take an old plastic soda pop bottle and leave it outside for at least an hour. Then squeeze and see what happens. Why do you think it might have done something different than if it was warm?
Cozy up inside and read a book!
