November : Making Frost
Materials
clean empty tin can
crushed ice
water
salt
Instructions:
Fill the tin can about half full with ice and add water and salt.
Wait and watch the frost form on the outside of the can.
The air around us can hold a lot of water which is called water vapor.
You can't see it, but it is there. We can see it when it condenses on
windows, cars, grass and spiderwebs. It is dew. Colder air can't hold
as much water, so what it can't hold turns into droplets. If the surface
is below freezing, what we see is called frost.
In the experiment we filled a can with crushed ice and water. This enables
the can to sit at around the freezing point for water. We need to get it
even colder, so that is why we add the salt. Salt lowers the melting point
of ice. This makes the water vapor in the air condense and freeze on
the can.
