What is energy?
100
Energy carried by electrons or electrical currents.
What is electrical energy?
100
When energy changes from one type to another.
What is a conversion?
100
Energy in motion stays in motion and energy at rest stays at rest.
What is Newton's 1st Law of Motion?
100
What are the three main stages of the water cycle?.
What are evaporation, condensation and precipitation?
200
A force (a push or pull) applied to an object which forces the object to move.
What is work?
200
Energy an object has due to its motion, position or condition.
What is mechanical energy?

When a flashlight is turned on, what energy conversion takes place
What is chemical and light energy?
200
For every action there is an equal and opposite reaction.
What is Newton's 3rd Law of Motion?
200
When water changes to a gas or water vapor.

The amount of push or pull of an object.
What is a force?
300
When water hits an object or building and runs off of it.
What is run-off?
400
Stored energy or energy that an object has due to its position.
What is potential energy?
400
Energy that occurs from vibrations.
What is sound energy?
400
A person riding a bike uses what types of energy.
What are mechanical and heat energy?

Explain Lab #4 (basketball and tennis ball).
When the basketball and tennis ball are released the force from the basketball flies up and hits the tennis ball causing it to pick up speed or accelerate making it shoot high into the sky.
400
When water changes back into a liquid.
What is condensation?
500
As a roller coaster car goes down a hill, its potential energy is changed into this.
What is kinetic energy?
500
How many types of energy are there and name them..
What are seven types including: sound, electrical, heat, light, chemical, mechanical and atomic (nuclear) energy?
500
This is an example of chemical energy being changed to sound energy.
What is using an ipod?
500
Explain Lab #5 (balloon rocket).
When the balloon is filled with air it is storing the potential energy waiting to be released. When the balloon is released it shoots across the string using the force from the air to make it move.

Explain the process of the water cycle.
The water on earth keeps going around and around and around (well, you get the idea) in what we call the "Water Cycle". This cycle is made up of a few main parts: evaporation, condensation, precipitation, runoff, and collection. Which help in the recycling of this water. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes into the air. Water vapor in the air gets cold and changes back into liquid, forming clouds. This is called condensation. Precipitation occurs when so much water has condensed that the air cannot hold it anymore. The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow. When water falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or it may end up on land. When it ends up on land, it will soak into the earth and become part of the “ground water” that plants and animals use to drink, or it may runoff the land and other objects and will collect in the oceans, lakes or rivers where the cycle starts all over again.
