Microsoft Word - Egg Drop Extra Credit.doc

Egg Extra Credit Program You and your partner must make containers to prevent damage when the eggs fall from the altitude. You can build your container with any material according to the following rules: 1) You can not use parachute or helium balloon as a lifting device. 2) Your container must weigh less than 114 grams (¼ pounds) including eggs. 3) Grading rules for obtaining additional units for raw eggs

You can earn up to 5% of the total test average by using a container that meets all of the above criteria for perfect landing (the eggs will not break). You have two success probabilities. Details on how to receive additional credit credits are as follows.

+ 1%: Create containers based on the above guidelines and show + 1% creativity. Write a short paragraph explaining the function of the container

Protect the egg from damage (What is the physics behind this?) + 1%: Calculate the theoretical velocity of egg / container shock

** What could prevent your container from reaching this speed? + 1%: Even if the egg goes down the container is falling

The Egg Drop Project teaches students to use logic and teamwork to prevent eggs from falling. There are many ways to make eggs. I will first explain the process and distribute the eggs to the students. Please set your egg drop parameters and deadline when your students need to fall or be ready to bankrupt. Many successful egg drop designs use a sturdy container to protect the contents from the initial impact of water droplets. These rigid containers can be plastic food containers or cartons. But a hard container alone is not enough to completely protect the egg. It is necessary to fill the inside of the container. Styrofoam, sponge, cotton ball, foam wrapping paper, even even a newspaper can be used to make excellent liners in containers. Give students time to practice various materials before laying eggs

For egg drop projects stretch over panty stockings or socks. Put eggs in hoses and socks, tighten the eggs, and put the socks on the edge of the egg. Paste or stick the stone to the bottom of the box, stretch the sock to the opening, and paste the top of the box to the box. Since this container is weighted, it falls only in one direction. Impact is absorbed by stone and cardboard. I will consider how the post office will transport fragile items and use this example to make egg containers. Use foam parts such as Styrofoam cups and wrapped peanuts. Fill the box with foam and place the eggs in the middle. When the box is securely attached, eggs are protected from collision and fall. Please test the device several times before submitting the final project to ensure that enough foam is used to protect the egg

A hard shell is not the only way to protect eggs when dropping eggs. A plastic bag is not like a casing, but it provides a structure to hold the filler around the egg. Add foam between the side of the egg and a small plastic bag, foam packaging or packaging of peanuts and other fillers. Put small bags in medium size bags and add more fillers around small bags. Place two bags in a large plastic bag and place a liner on top of the center bag. Please try to limit the course to a specific teaching material set, such as to make all fills be eaten. Please try using cereals such as rice puff and wheat as padding. Fruit is another option. Please use grapes, cherry tomatoes, or orange wedges between the egg and the side of the box or container. Fluid filled cells function in the same way as air filled sacs. Considering that the egg has to fall but it is not necessary to hit the ground
