We dropped steel balls through corn syrup at four different temperatures, 24°C, which was room temperature, 10°C, 47°C and 60°C. At each temperature we dropped 5 balls. This chart shows our results:

Although there was considerable variation from one drop to another, the colder the corn syrup the longer it took for the steel ball to drop.The colder liquid is more viscous.

   Repeat this experiment with different liquids. Try various kinds of vegetable or mineral oil, honey, and water.
2. In our results, the time was shorter from one trial to the next at 10°C, generally longer from one trial to the next at 47°C and 60°C. At room temperature the times were pretty consistent. What do you make of this?
