6.MS-ETS2-1 and 2-2 Properties of Materials

Front

What are the two key properties of materials that should be tested when building a catapult to launch marbles the greatest distance?

Back

Strength and flexibility.

Front

What does it mean for a part of a bridge to support a large amount of weight?

Back

It means that the material can bear heavy loads without collapsing.

Front

What is a defining characteristic of concrete in construction?

Back

Concrete is high in strength.

Front

Why would a student use a metal pin to hold straws in place on an anemometer?

Back

The pin is thin and strong.

Front

Which type of case would best protect bird eggs?

Back

A hard metal case with flexible foam lining.

Front

Define 'strength' in the context of materials.

Back

Strength refers to the ability of a material to withstand an applied force without breaking.

Front

What is 'flexibility' in materials science?

Back

Flexibility is the ability of a material to bend without breaking.

Front

Explain the term 'malleability'.

Back

Malleability is the ability of a material to be deformed under compressive stress, often characterized by the material's ability to form a thin sheet.

Front

What does 'hardness' refer to in materials?

Back

Hardness is a measure of a material's resistance to deformation, particularly permanent deformation, scratching, cutting, or abrasion.

Front

What is the significance of 'density' in materials?

Back

Density is the mass per unit volume of a material, which affects its weight and buoyancy.
