To protect the egg during the egg-drop challenge, the three design strategies that will help are:
1. Add a parachute to the top of the container: A parachute can help slow down the descent of the container, reducing the impact force when it hits the ground. This strategy allows for a gentler landing, which can help protect the egg from breaking.
2. Wrap the egg with multiple layers of bubble wrap: Bubble wrap provides cushioning and shock absorption, which can help protect the egg by absorbing the impact energy when the container hits the ground. The multiple layers create a protective barrier around the egg, reducing the risk of it breaking upon impact.
3. Pack the egg in the container with cotton balls: Cotton balls act as a soft cushioning material that can absorb shock and prevent the egg from moving around inside the container during the drop. This strategy helps to stabilize the egg and minimize the chances of it breaking upon impact.
By combining these design strategies – parachute for a softer landing, bubble wrap for shock absorption, and cotton balls for stabilization – the students can increase the chances of their egg surviving the drop intact.
