Today we learnt what STEM was. STEM stands for Science, technology, engineering & maths. We made our catapult out of 7 popsicle sticks and 5 rubber bands. We fired our projectile 3 times, and measured the distance of how far it went. Round 1, the distance is 2.56 meters, round 2 was 2.72 meters and round 3 was 2.36 meters.
