Today we did a demonstration lab about density. The challenge is now on. Who can make a bigger density tower - Mrs Buzak or one of her students? A simple density tower is located on page 60 in the text book. If you want to keep the tower for later - don't use milk as it will turn sour!! Later if students don't want to keep their towers, I would love to have them as decorations around the room. Food coloring is allowed to show the different layers. The students are going to send me a digital picture of themselves with their tower and I will post the different towers on the blog with mine as well. The towers will be due on Friday Oct 17.
