tend to (stick together/flow over) one another.
Gases have
______________ shape and _______________ volume.
The molecules
in a gas are (slow/fast) moving and (close/spread apart).
Both ________
and ______ take the shape of their container.
When a solid
changes to a liquid it is called _______
When a liquid
changes to a gas it is called ________.
When a gas
turns into a liquid it is called _____.
When a liquid
turns into a solid it is called __________.
Mass is the
amount of ______ in an object.
Objects that
float in water are (more/less) dense than water.
Objects that
sink in water are (more/less) dense than water.
Conductors are materials that (allows/ does not allow)
things to flow through them well.
_____________
are good conductors of heat and electricity.
Insulators
are materials that (allows/ does not allow) things to flow through them well.
Wood,
plastic, glass and cotton are good (insulators/conductors) of electricity (they
hold it in).
(Solid/liquid)
objects are better sound conductors than gases.
A ______________ is a combination of two or more substances.
In a (mixture/Solution), each substance
keeps its original characteristics.
A _____________ is when one or more
substances are dissolved in another substance.
It is a special type of mixture.
Dissolving is a physical change.
Dissolving does not mean
disappearing, write a short statement of what it does mean.
What process or method will speed up the process of dissolving a
solute in a solvent (salt in water).

Give an example of each.
Draw an open circuit and explain why it can
not light the bulb. You must have a battery, wire and a light bulb in your
schematic.
Using a red crayon or marker, draw a
component or “fix” the incomplete circuit and make it complete.
When electricity moves through these wires
what type of effects occur? (remember the compass?)
Light travels in (waves, straight line,
both)
When light passes through one type of
material at an angle, the light bends. This is called ________.

known as ________________.
There are 2 types of lenses. List what they
are and draw them below.
Give real world examples of objects that
refract light.

Describe sound energy.
In the movie Star Wars, the Millennium
Falcon could not make a sound and could not be heard. Why is this so?
Sound travels best through what substance?
An ice-burg has more heat energy than a lit
match. Why?
