Matter

LO: SWBAT classify and describe matter based on
magnetism.

DOL: Given scenarios, SW correctly classify and
describe matter based on magnetism in at least 4 of 5
questions.

SCI.4.6A classify and describe matter using observable physical properties, including temperature, mass, magnetism, relative density
(the ability to sink or float in water), and physical state (solid, liquid, gas);
SEPs 4.3A, 4.3B
RTCs 4.5A

What is one way to

classify metals?

What did you
observe about

which objects are

magnetic?

Prediction (What

will happen?)

Result (What

really happened?)

How can we test an object for the property of magnetism?

16

How can we classify matter?

1 Notice

List as many different kinds of
observable matter as you can.

2 Identify

Read about the physical

properties of matter. Write what

you learned. Include at least

one vocabulary term.

3 Connect

Describe how you could use
physical properties to classify

an unknown substance.

18

Many common objects including plastics, paper and wood are
not attracted to magnets. Some metals such as iron and cobalt
are attracted to magnets, and others such as aluminum and
copper are not attracted to magnets.

Steelis another example of a metal that is attracted to magnets
because it is a combination of iron and other materials.
