This unit 3, I am using experiments that I found in different websites.
For this experiment you need a wooden block (I used my toddler’s block), rubber band, nail, candle and cardboard arrow (size of the wooden block).
Follow instruction in here.
I used this to review ordinal numbers, instructions, and imperatives.
So far it was a BIG success in 3rd and 4th grade. However, I was truly concern about using fire on a classroom and near students. No burned hair, so everything is alright.
Watch photo of experiment at my home.
Another video about th power of heated rubber band, watch this one.
