Sample entry 2

Today we did an experiment where we filled a bucket with ice and added salt into it to see what happens to the temperature.

This is what we recorded:

We learned that water freezes at 0 degrees, and so ice has a temperature of 0 degrees celsius. But when we added salt, we found that the temperature dropped below 0 degrees. Using this as a freezer, we will try to conduct experiments to see what things we can freeze, and what temperatures these freeze at. It seems that the lowest this freezer goes is -6 degrees, so if the liquid we choose requires a lower temperature to become frozen, we will have to find another way.
