7. _____________ The scientists writes, "Therefore I suggest that my hypothesis was supported because the
salt water freezes at a lower temperature then the fresh.
8.____________ A scientist wants to find out: Does sea water freezes at a lower temperature than fresh water?
9. ____________ The scientist creates a list that includes, 2 beakers, 2 liters of water, 70 grams of table salt,
refrigerator. Then the scientist does the following in the laboratory:
1. Fills 2 beakers each with 1 liter of fresh water
2. Dissolves 35 grams of table salt in one of the beakers.
3. Places both beakers in a refrigerator whose temperature is -1 C.
4. Leave s the beaker in the refrigerator for 24 hours.
10.____________ My prediction is that if I put a beaker of freshwater and a beaker of saltwater in the freezer
then the freshwater will freeze first.
