1. Updated September 2011 Atomic Trampoline Experiment

2. Updated September 2011 Does designing a material on the nano or molecular scale really do anything productive on our level?

3. Updated September 2011 By engineering an alloy on the atomic level, the metal gains a list of novel properties that can be used in several applications.

8. Updated September 2011 LiquidMetal Alloy Properties High Yield Strength High Hardness Superior Strength/Weight Ratio Superior Elastic Limit High Corrosion Resistance High Wear-Resistance Unique Acoustical Properties

9. Updated September 2011 Gather several types of metals to compare with the new alloy: Aluminum Brass Copper Steel Titanium Collect a clear tube, steel ball and a timer to time the bounces. Elastic Strain Demo

10. Updated September 2011 1.Drop the steel ball from the same height on each type of metal. 2.Count the number of bounces and record them. 3.Use a computer recording software to record the bounces and time. 4.Draw a bar chart displaying the bounces for each metal. 5.Discuss applications for a metal that repels forces, doesn’t rust, and has low friction. Elastic Strain Demo

11. Updated September 2011 This is a set of audio recordings of several metals bounce test. It is easier to count the number of bounces visually rather than audibly. Image by HighPoint Learning
