2. What apparatus is used in today’s lab?
3. True or False
The freezing temperature of Sea Water higher than fresh water?
4. True or False

5. True or False
In winter, while many freshwater lakes freeze over, much of the ocean stays in liquid form

6. True or False
In this experiment, you will use a Temperature Probe to measure the temperature of water as it cools and then freezes.
