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
How does electricity work and how do we get access to it at home?
Electrical energy (electricity) is the most common form of energy used as it can be delivered from place to place easily. Wire are excellent conductors that carry energy away from power plants to houses and cities. We access it through our outlets.
Who thought of the first law of energy?
Albert Einstein
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.
What type of Energy is transfered through vibrations in the air?
Sound Energy
Give an example of transferring energy.
Answers may vary. Ms. Sousa will say if they were right or not.
What is an insulator?
An Insulator is a material that does not carry electricity.
Pollution is a harmful addition to the natural environment.
What is Electrical Energy and how is it created?
Electricity is a form of energy that can gives things the ability to move and work by using outlets. It is the flow of tiny particles called electrons. Thus, electricity is the form of energy that we get when electrons flow from one place to another. Usually made from natural resources.
What type of energy do plants absorb to help them grow?
Light Energy
The ability of an object to cause motion or change is known as .....
What is Energy?
What does generating electricity mean?
Generating electricity simply means, making electricity.
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 Energy?
Energy is the ability to do work as it allows things to move, grow or change.
What are fossil fuels? Give at least 1 example.
Fossil fuels are made from decomposing plants and animals. These fuels are found in the Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels.
What is the first law of energy?
Energy cannot be created nor destroyed, but only transformed.
Is sunlight a renewable or nonrenewable resource?
Renewable.
What is the biggest consequence of using non-renewable resources?
Pollution and global warming
What is potential and kinetic energy?
Potential energy means the energy is not being used yet, but has the ability to be used. Kinetic energy is energy in motion.
Does a ball's energy increase or decrease as it moves slower?
Decrease
What types of energy travel in waves?
Light, heat and sound energy.
What is static electricity? What does repel and attract mean?
Static electricity is when electrical charges move from one object to another. Everything is made up of tiny particles that are too small to be seen. These tiny particles can have a electrical charge, positive or negative.
Repel = push away
Attract = Pull toward
