Science Saturday: Hanukkah

This proved to be a bit difficult for me, but here are my thoughts:

- Using the scientific method, light a candle and make observations at 30-60 second intervals in the beginning and 10 minute intervals once it has been burning a bit. This will teach observation skills, allow the child to form a hypothesis, and open the door for a discussion of chemical changes versus physical changes.

- You could also discuss water and oil mixtures and even perform some experiments. Try mixing water and oil and observe what happens. Now add a little dish soap and try again, making an emulsion (vocab word)). You could also use a jar filled 3/4 with water and then top it with oil. now sprinkle some salt on top and watch as the salt draws the oil through the water. You can make it more fun by coloring the water and/or oil first.

I wish I had more for you. Feel free to share any ideas you may have.
