Density

Which option best describes what density is?

• The amount of matter in a substance

• The measure of the amount of mass in a given volume

• The amount of space an object takes up

• A chemical property of matter

Choose the option that you think is the most dense

• golf ball

• ping pong ball

• a balloon filled with air

• an empty box

If an item is more dense that water it will...

• float

• sink

• dissolve

• explode

Is air matter? How can you tell?

• No, because there is no air in space

• Yes, because I use it to breathe

• No because it is invisible

• Length x Width x Height

• Height + Width + Height

• (Length + Height) x Width

Which of the following is NOT a step in finding the volume of an irregular shaped solid object?

• Measure and record an amount of water in a graduated cylinder

• Add the object to a graduate cylinder with a known amount of water and record the new water level

• Use the formula to multiply the length by the width by the height

• Subtract the water level of the with the object in it from the amount of water before the object was introduced
