renewable and non-renewable energy
What is a non-renewable resource? Give an example.
Non-renewable resources are resources that will not replenish themselves in a lifetime. For example, fossil fuels.
Name 3 types of energy.
Could have said any of these:
- Chemical Energy, Electrical Energy, Heat Energy, Mechanical Energy, Solar Energy, Kinetic Energy, Potential Energy
what do we use electricity for?
example: lights
What are the 2 types of circuits used for electricity?
What is a conductor?
A conductor is a material that allows electricity to flow easily through it.
What is a renewable resource? Give an example.
A renewable resource can be used over and over again without any effect on the environment. For example, the sun, wind or water.
What is solar energy?
Also known as radiant energy, is energy created with the use of the sun.
Identify the conductor in this list: copper wire, rubber glove, plastic fork
what is copper wire
This type of circuit has multiple paths for electricity to flow
What is parallel circuits
What is an insulator?
An Insulator is a material that does not carry electricity.
what is clean energy and expensive
how does current electricity flow?
what is in a continuous path/ always moving
The ability of an object to cause motion or change is known as .....
What is Energy?
Name an item that is both a conductor and an insulator?
what is a frying pan
Name the benefits and drawbacks of using solar energy?
Benefits: Renewable source of energy that we can't run out of and no pollution or by-products are created outside of the solar farms/panels.
Drawbacks: Costly to build and install solar panels and the sun doesn't shine in one area all day, therefore it is inefficient.
what is kinetic energy?
What is energy that is put into motion
Electricity that is powered by water
Hydroelectricity
The three main components required for a simple circuit are wires, a load, and this
Power source/ battery
Is sunlight a renewable or nonrenewable resource?
Renewable.
What is the biggest consequence of using non-renewable resources?
Pollution and global warming
Potential energy
what is energy that has not been used yet, but has the potential
Does a ball's energy increase or decrease as it moves slower?
Decrease
What happens to the other light bulbs if you break or turn off one light bulb in a series circuit?
What is they will all turn off
What is static electricity?
Static electricity is when electrical charges move from one object to another. These tiny particles can have a electrical charge, positive or negative.
