Introduction to Physical Science Additional Resources

Module #1

The scientific method:

Matter: Anything that has weight and takes up space.

all matter has volume and weight
three states of matter: solid, liquid and gas

Molecules in Solids, Liquids and Gases

A solid can become a liquid and a liquid can become a gas.

A gas can become a solid. (example: frost)

A liquid can become a solid

Properties change when matter changes it’s state

 


Atoms And Molecules:
ATOM – THE SMALLEST CHEMICAL UNIT OF MATTER
MOLECULE – TWO OR MORE ATOMS LINKED TOGETHER TO MAKE A SUBSTANCE WITH UNIQUE PROPERTIES
ELEMENTS – SUBSTANCES MADE OF OF THE SAME ATOMS
COMPOUNDS – SUBSTANCES MADE UP OF MORE THAN ONE KIND OF ATOM OR MOLECULE
MIXTURES –

Atoms, Elements: Eureka #22

Basically atoms and elements are the same thing. 

An atom is just the smallest amount of an element.

Eureka Episode #23 Electrons

Measurement and Units:

Measuring Matter:

 

Why the metric system matters – a Ted Ed video by Matt Anticole

 

Great video on manipulating units using steps and a silly sentence.

And more help for converting between units:

 

 

 

And now… Converting between systems! Yes, the bane of physical science and chemistry and yet once you understand it, it’s fun.  Well, for me anyway.

concentration:
concentration – the quantity of a substance within a certain volume

Dilute: A small amount of solute per solvent

Concentrated: A large amount of solute per solvent

The air we breathe is made up of a solution. Solutions can be separated again.

The ability of something to be dissolved is called its solubility.

Saturation is the point at which no more solute can be dissolved into a solution.
