Materials Engineering: Replicating an Artifact Material Properties What are the properties of the materials we can use for our replicas and which properties help us to meet the design criteria?
This petroglyph is an artifact that was found on a far-off island. It was made by people from an ancient civilization. Very little is known about the people who created this artifact, so archaeologists are very excited to study it.
The Eisenberg steAm Club has received a memo from the museum.
What did the museum say are the criteria for your replicas? What is the constraint on your replica design?
What are the properties of the materials we can use for our replicas and which properties help us to meet the design criteria?
How would you describe this material? What does the surface look and feel like? Can you see grains or "pieces" in the material? What size are they? Which materials would be your top two choices for designing your replica? Why? In what ways can we sort the materials? What are the three categories of rocks? What is different about these three categories of rocks? - Wear your safety goggles at all times. -Hold your nail like a pencil and carve three straight lines into one side of each material. -Each line should be approximately 1" long. -Carve the first line ONE time. -Carve the second line THREE times. -Carve the third line FIVE times. -Note on the Properties of Materials chart.
