Engineer’s week - egg drop challenge!

​It’s Engineer’s week!! Junior Infants, 5th and 6th class completed a challenge based on our pal Humpty Dumpty. The children investigated 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, stickle bricks and duplo. The walls had to stand by themselves by the end of 30 seconds with Humpty resting on top. Next, we tested the best materials to protect Humpty Dumpty from breaking when he fell. We wrapped an egg in a variety of materials (cotton wool, newspaper, bubble wrap, tissue, fabric)and then placed it into zip-lock bags. The boys & girls then dropped each bag from the wall  and observed the results.
