How can we describe matter?

Set Purpose

› We are going to read about how we measure matter.

› We are going to find out the properties we measure and the tools we use for measuring them.

How can we describe matter?

Quick SUMMARY

› Mass is the amount of matter an object has.

› We measure mass with a balance. › An object's mass is the same everywhere,

but its weight may be different. › We measure volume by measuring the

amount of space that an object occupies.

Questions

› What tool do we use to measure the mass of an object?

› Could you measure the volumeof a feather by placing it in a measuring cup of water? Why or why not?

› Is the measurement of the mass or weight of a carrot be affected if you cut the carrot into pieces?

How can we describe matter?

Science Objective

› We will determine the physical properties of matter using metric measurements that incorporate tools such as rulers, thermometers, balances.

How can we describe matter?

Quick SUMMARY

› Density is a measure of the amountof matter (mass) in a certain amount of space (volume).

› One way to study density is by observing buoyancy.

How can we describe matter?

Questions

› What do we mean by density? › If an object floats in water, what does that

tell you about its density? › What two properties do you need to

measure in order to determine the density of an object?
