Metal Mania
This type of element is shiny, conducts electricity, and can be hammered into shape.
Metal
I am a metal that is lightweight, shiny, and often used to make cans and airplanes. I am the most abundant metal in Earth’s crust.
Aluminum
A sample of a substance melts at exactly 80°C every time it is tested. This is evidence that the sample is most likely a ______.
Pure substance
A sample has a mass of 60 g and a volume of 25 cm³. What is its density?
2.4 g/cm3
Bananas are radioactive. True or false?
True
A scientist discovers an element that is shiny and only conducts electricity under certain conditions. What category does this element most likely belong to?
Metalloids
This toxic metal was once used in products like paint and pipes but can damage the nervous system if it enters the body.
Lead
A substance melts from 45°C to 52°C. Is it probably pure or a mixture?
Mixture
Cube A and Cube B have the same volume. Cube B has twice the mass. Which is denser?
Cube B
What American video creator won a president's medal for his work in science and education?
Bill Nye
A student finds an element that is dull, brittle, and does not conduct electricity. What group does it most likely belong to?
non-metal
I am a metalloid used in computer chips because I can sometimes conduct electricity. I helped create modern technology.
Silicon
A graph shows a flat line while a substance boils. What does this suggest?
pure substance
Three samples have the following densities:
Which sample is most likely made of iron
Sample B
What is Teacher Simmona's favorite color?
Red
Would oxygen, silicon, or aluminum be the best material for making a cooking pot? Explain why.
Aluminum because it conducts heat well and is a metal.
I am a metal that is excellent at conducting electricity. I am found in electrical wires, but mining me can create environmental problems.
Nitrogen (N)
This property explains why aluminum can be made into thin sheets for cans without breaking.
malleability
A student measures a metal cube with:
The teacher says another cube made from the same metal has a mass of 180 g. Predict the density of the second cube.
Same density
Octopuses have two hearts. True or false?
False
Name two properties that make copper a good choice for electrical wires.
conducts electricity, ductile, flexible, good conductor.
I am a shiny metal that is valuable because I resist corrosion. Unlike many metals, I do not react easily with oxygen.
Gold
A company needs to make very thin wires for headphones. The material must be stretched into long, narrow strands without breaking. Which property is most important?
Ductility
Two atoms have the same number of protons but different numbers of neutrons. They are called these.
Isotopes
What city is Teacher Grace from?
Madison
