Question:
Out of orange juice, water, milk, and pop, which liquid freezes the fastest?
Variables
1. Using more liquid in each cup.
2. Checking on them every 15 minutes.
3. Using different liquids.
4. Using glass cups instead of plastic.
Which Liquid freezes the fastest?
Experiment with liquids in cups
Experiment with Popsicle Sticks
Experiment in the freezer
Experiment looking at frozen liquids
Observations
Materials
After 30 minutes:
I observed that the orange juice and pop got slushy. The water is turning into ice. The milk is getting hard around the cup.
After 1 1/2 hours:
I observed that the orange juice and pop got more slushy. The water turned completely into ice. The milk was only liquid in the center.
Conclusions
If I put liquids into cups then check every 30 minutes, water will freeze the fastest.
Water freezes fastest because water doesn't contain other ingredients. Water is H2O, hydrogen and oxygen.
