As part of our Frozen-themed unit we did an experiment to see how different liquids freeze differently. Our question was “Do all liquids freeze the same?” States of matter are one of the girls’ favorite science topics lately so this experiment was right up their ally. I loved that it was such a quick and easy experiment that they found interesting.
First we gathered a bunch of different liquids…
Need ideas? Here’s what all we used:
- Orange Juice
- Olive oil
- Tomato Juice
- Corn syrup
- Chocolate syrup
- Dish soap
- Hydrogen Peroxide
- Apple Juice
I made these worksheets for them to use as we went through the experiment. I thought it was interesting that the girls each had a different hypothesis–one saying they will all freeze the same and the other saying that they will freeze at different times. The ice cube tray diagram allowed us to keep track of which liquids were in which spot.
We then placed our ice cube tray into the freezer. Then at our set intervals we would take out the tray and record our observations. I just had them make an F in each square that was frozen when we checked. After doing the experiment I realized it would be better if we had checked after 10 minutes, 1 hour, and then 4 hours so I changed the worksheets to reflect that.
The girls were able to come to the conclusion that different liquids freeze at different rates. We were also able to introduce the idea of viscosity since they were able to see how it affects the rate of freezing as those with a high viscosity froze more rapidly than those with a low viscosity.
