OpenSciEd 8.1 Study guide

If you were designing and evaluating the materials being used in another design, what properties or materials would you expect to see in a good protective device if it were cut open?

Draw a model of the material structure you would expect to see in the design described in 1a. In your model, label each design feature. For each design feature you label, explain in words how the structural properties help it function as a protective material.

When any of the devices are used in the examples above with an egg inside, the device will make contact with the ground. Draw and label a diagram that shows all three of these objects (egg, device, ground) in contact with each other at the point in time when the collision with the ground first starts.

A person is testing their egg drop project which has some materials that will cushion the fall. After the test, another person wants to test whether an egg that is dropped on the device will break or not. The person thinks that the second egg will not break on the device because of the cushioning material. Do you agree or disagree? Explain why.

Use words and pictures to show the structure of your design solution. In your design solution, make sure to label the different parts and materials used in the structure. Draw the proposed design around your egg while also showing how you would get the egg in and out of the device.

Explain how the materials in your design in 4a will function to reduce peak forces on an egg in a collision. Describe how any smaller-scale structures (small and microscopic) that make up your materials help contribute to their function.
