6th Grade Science - Week 10 CCA Review
1. Metals are located to the left of the stair step line on the Periodic Table of Elements.
Metals are usually shiny, malleable (able to be flattened into thin sheets), ductile (able
to be pulled into wire), and good conductors of heat and electricity.
2. Nonmetals are located primarily to the right of the stair step line on the Periodic Table.
Nonmetals are usually dull, brittle, not malleable or ductile, and poor conductors.
3. Metalloids are elements that have some properties of metals and some properties of
nonmetals. They are found on the stair step line on the Periodic Table. Metalloids are
semiconductors, which means they can conduct electricity at high temperatures.
4. Energy cannot be created or destroyed. It can be transformed from one type to another.
5. Potential Energy is stored energy that is available for later use. Examples include a
stretched rubber band, a diver standing at the top of a high dive, and a book sitting on
the edge of a desk.
6. Kinetic Energy is the energy of motion. When something is moving, it is a good example
of kinetic energy. Examples include a soccer ball flying through the air, a person running,
and a ball rolling down a hill.
7. When an object is not moving, it has no Kinetic Energy. When an object is moving, it has
some Kinetic Energy.
8. Chemical energy can be found in fuels like coal, oil, natural gas, and other things that
can be burned. It can also be found in batteries and food.
9. Light energy is also called Electromagnetic energy and Radiant energy. It is the energy
of light waves, like microwaves and x-rays.
10.Electrical energy is the movement of electrons (electricity).
11.Mechanical (Motion) energy is the movement of matter from one place to another.
12.Be sure to study the notes on Potential and Kinetic energy transformations for Roller
coasters, Pendulums, and Bouncing Balls. (Found in your notebook.)
13.Warmer substances transfer heat to cooler substances until their temperatures are the
same. For example, if a cool spoon is placed into hot chocolate, the spoon’s
temperature will increase and the hot chocolate’s temperature will decrease as the hot
chocolate transfers some of its heat to the spoon.
14.Heat energy can be transferred from one substance to another in three ways:
Conduction, Convection, and Radiation.
15.Conduction is heat transfer from one substance to another by direct contact.
(Substances are touching.) An example is the hot chocolate and spoon, above.
16.Convection is heat transfer in a liquid or gas by currents. A lava lamp is a good example.
The “lava” heats up, becomes less dense, and rises. It then cools, becomes more dense,
and sinks. This process continues in what is called a “convection current.”
17.Radiation is heat transfer by electromagnetic waves. The sun warming the sand on a
beach is an example of radiation.
