Molecules on the Move

Molecules on the Move

About this Experiment

In this experiment, we're going to learn about molecular motion and how it is affected by temperature.



  1. Fill one drinking glass about halfway with cold water and the other with warm water. If you have more than two glasses, feel free to try even more temperatures.

  2. Put about 5 drops of food coloring in each glass, trying not to give any of them a head start. You can even use both hands or ask a labmate to help.

  3. Carefully observe how the food coloring spreads throughout the water. Which one is spreading the quickest?

Analysis and Conclusion

Hmm... it seems nobody's added a conclusion for this experiment yet. You can suggest one here.

The daily "did you know?"

Bees were once taught by scientists to count up to four, and were even later shown to understand zero.
