You can also attach a thread to the top rotor assembly. An egg is multi-functional: yes it's food, but it is also a valuable engineering lesson. One solution is to add some weight at the tip to make sure it is the part touching the ground first. To make it a harder challenge, you can limit the number of straws and pieces of paper that are allowed in the design. Take a handful of the straws, spread them apart at the top, and let the egg sit in between them all, keep them together by attaching the rubberband around the straws and egg under the egg. When the egg hit the ground the ground will exert of force over a period of time that will cause the egg to accelerate or decelerate if you like thus changing its momentum to some mvo to some mvf.
Make a box out of paper. If you can make string that's thin enough, you can use a large-sized needle to. Once they were finished they headed back inside to discuss the results. Though, these days, using all the available internet resources is a real way of finding solutions. Many successful egg drop designs use sturdy containers to protect the contents from the initial shock of the drop.
You can of course alter the length of these blades. If not, the egg might move around inside. The point was to get the kid to think and try to come up with something on his own I know thinking is hard for a lot of people. For example, teachers can set limits on materials students can use. Make the whole large enough to fit one of the skewers through. Insert the egg into panty hose or attach an egg-protecting container to a bungee cord to prevent the egg from hitting the ground.
The basic idea is to surround the egg with enough of a cushion using these foods to reduce the force of the impact the egg faces once it lands. I think the point of the exercise is to come up with a way to drop an egg without breaking it. Two problems - we have only 100 sticks, and the test jig is less than 40cm high. Tie the egg in place using rubber bands. The students brought in supplies from home and built their own containers in class.
You may have more control of rigidity and landing if you fold the … paper like an accordion bellows and layer them criss-cross. And the kids always get super excited to do this project so get ready for lots of screams of delight! Also, make sure the cylinder is stuck down good, and in the middle of … the box. We tried twice, and both times it failed. If it's not fitting make sure the bulk of the excess plastic bag is under the egg when you place it in and the egg is sitting vertically in the tube eggs are much stronger in this orientation. I did look at other posts in this subreddit concerning egg drop experiments and it seemed like all of them were able to use some sort of adhesive. You can also wrap the egg in packing material, like bubble wrap, packing peanuts, or inflated plastic packets.
It could be a cardboard or plastic box, or you could even construct a box frame out of metal clothes hangers. This is very helpful if you're not the one dropping it. It is such a classic physics science fair project. This assembly will protect the egg. Forces in Simple Triangle: 200kg weight on apex.
Low mess and great learning with a simple egg drop activity all ages can enjoy together. Make sure that the handles are near the sides of the box so that enough air can get inside the bag as the box drops. It's almost time to test it. I think the point of the exercise is to come up with a way to drop an egg without breaking it. It should be a pretty snug fit.
If you know a formula to calculate the area of parachute needed for however much weight is placed in the basket, this would be greatly appreciated. Adding tennis balls on the side of the frame is one way to do this. You may have to experiment with varying degrees of paper compression. Of course, there is a worksheet for kids to record their designs and changes through out the process. You can go back later and reinforce these small drops with more glue after everything dries. Through the project, students learn engineering design process, physics, material science, and if it is a team project, team work.
When you drop the egg, make sure that it lands on the cushion. We also added some scrambled paper on top of the egg as a cushion to mediate the potential force between the egg and the straws. We tried twice, and twice the eggs cracked. Fill a large, wide box with a thick layer of heavy-duty bubble wrap or similar packing materials. We tried the new design.
