Our summer has been all about keeping things simple and so far our science projects have been just that. We set up the walking water experiment (shown above) so quickly...two glasses, food coloring in water, a strip of paper towel and a raised surface. It took about a week for the water to completely change glasses, so I was glad that we kept the experiment on the dining room table as it made for easy observation during meals.
The other experiment I wanted to share is our fizzy exploding bags. Still an easy one, but it takes a little more prep time. Jack and I got the time-release packets ready while the girls were napping and then we blew up our Ziploc bags when Dad got home. They didn't give as much of an explosion as I had expected, but the kids loved setting them off. Make sure you do this one in a place you can hose afterwards as it left a nice white powder everywhere.
