This week we worked on Halloween theme automata. Take a look at the instructions for simple automata here. The star is the "Witch in a Cauldron" by Dawna.
This week, in preparation for Halloween. We did some spooky science. One of the activities was making bubbles with dry ice. 1) Put a chunk of dry ice and a half cup of warm water in a cup. 2) dip a pipe cleaner into bubble solution 3) Slide the pipe cleaner over the mouth of the cup to stretch a film over the opening 4) Watch the escaping CO2 gas fill the bubble with fog Or just drop a chunk of dry ice directly into the bubble solution. This will make a foggy foam "grow" out of the cup. We use Exploratorium's home made bubble solution recipe.
This week some of the kids decided to make model motorcycles. materials: hardboard, craft sticks, bbq skewers, pine scrap wheels. Vroom Vroom! Use a scroll saw to cut out the body. Use a drill press (dremel is big enough) to drill out the craft sticks.
