YAYYY! Science test! Haha, I know that you all are not as excited as I am about the Science test, but you should be excited about all that your students are learning! We have covered mass, matter, density, weight, gravity, transparency, translucency, and opaqueness. WHEW! It's been a lot, but I am so proud of my kiddos and how much they know!
Just in case someone has forgotten their study guide, here is another copy!
Chapter 6 Science Study Guide
•
Light travels in
a straight path.
•
A pan balance is
used to measure mass.
•
All substances
are made of matter.
•
Matter is made up
of particles that cannot be seen.
•
In a liquid, the
particles of matter can move more than they can in a solid.
•
A solid has a
definite shape and takes up a definite amount of space.
•
A liquid does not
have a definite shape but takes up a definite amount of space.
•
A gas does not have
a definite shape nor does it take up a definite amount of space. A gas does
have volume and mass.
•
An object that
absorbs all light that strikes it looks black.
•
Density can be
found when you divide the mass of an object by its volume.
•
Matter is anything
that has mass and takes up space.
•
Weight measures
the amount of gravity between an object and a planet.
•
Light is not
considered matter because it does not take up space.
•
Volume is how
much space a substance takes up.
•
The metric unit
for weight is the newton (N).
•
The metric unit
to measure mass is a gram.
•
A kilogram is the
same as 1,000 grams.
•
A marble has more
mass than a piece of popcorn (even theough they are similar in size) because
the particles inside a marble are packed together more tightly than the
particles in a piece of popcorn.
•
Objects weigh
less on the Moon thean they do on Earth because the pull of gravity on the Moon
is much less that the pull of gravity on the Earth.
•
An object's
length is the number of units that fit from one end to the other.
•
All matter has
mass, volume, and state.
•
An object will
float when its density is less than the density of the liquid or gas in which
it is placed.
•
The pull of
gravity is stronger the more mass it has.
•
A physical change
begins and ends with the same type of matter.
•
A change of state does not affect an object's mass.
•
When any liquid
(EXCEPT water) is cooled, the particles move closer together.
•
Boiling is a
change of state from a liquid to a gas.
•
A change of state
is a physical change in which one state of matter changes to another.
•
Boiling and
evaporation cause liquids to turn into gases.
•
Cutting, crushig,
tearing, bending, and stretching matter are all physical changes.
•
If you add heat
to a solid, its particles move faster.
•
Nuclear energy
comes from the tiniest particles of matter.
•
Radiant energy
can move through both air and space.
•
A concave lens
causes light to bend outward from the center so light rays spread out.
•
A convex lens
bends light rays toward the center.
•
White light is
made up of every color of light.
•
Glasses and a
hand lens have convex lenses.
•
A lens refracts
light.
•
Light bounces off
an object in reflection.
•
Glasses with
concave lenses will help you to see objects that are far away.
•
Light travels
through the eye from the cornea to the pupil to the iris to the retina.
