Mostly what I learned from this activity is that even though science really needs to be interactive and hands-on, you do not need the actual materials to make it that way! Using these wonderful technology programs, you can bring the outside world right into the classroom so that students can observe it, manipulate it, experiment with it, and make predictions and conclusions about it. Through technology, hidden doors to science are suddenly opened wide!
