Day 323 - In the name of Science
One of our Grade 4 classes was working on simple machines today. Their first task was to create a catapult to launch marshmallows at their teacher. They had to figure out the technique that would get their marshmallow to the target. Miss C. reminded her students that safety must come first as she placed on her own safety goggles. The kids had a great time and were quite innovative. Luckily for Miss C., none of them hit their mark but they got pretty close. Those who achieved the most distance and accuracy demonstrated their technique for the other students. The experiment was followed by a discussion of the 3 classes of levers and then they built various simple machines with Lego kits. It's a hands-on learning experience I'm sure they won't soon forget.
