Junior Infants S.T.E.M experiment is based on our friend Humpty Dumpty. The children wondered if we could investigate what materials could protect Humpty from cracking when he falls off a wall.Our first activity was based on Humpty Dumpty and structures. We know that Humpty Dumpty likes to sit on high walls so we got into groups and built walls as high as we could using a variety of materials; lego, wooden blocks, cubes and duplo. We learned a lot about what makes structures sturdy – we discovered that wide bases were the key to making sure they stayed standing. We also discovered that the duplo wall was the safest and tallest for Humpty Dumpty to sit on. Next, we tested the best materials to protect Humpty Dumpty from breaking when he fell. We placed a variety of materials (cotton wool, pom-poms, tissue, paper,), into zip-lock bags and placed an egg into each one. The children then dropped each bag from the tallest wall.We were really surprised by how well the pom poms protected the egg.
