On Halloween Day we decided to have some fun building density towers. Students made great observations of our demo tower, asked excellent questions about how we could change the experiment, and then collaboratively designed and conducted experiments using liquids and solids of their choice. It was an excellent morning!
For many of us one lasting lesson will be not to swirl the old bottles of food colouring found on the Hart Highlands shelves - the plastic may have lost its structural integrity. What a mess!
