### 100

What are the forms of energy referenced by MR. SCENT
Mechanical, Radiant, Solar, Chemical, Electrical, Nuclear, Thermal

### 100

Name one renewable, one nonrenewable, and one inexhaustible resource
What is...answers may vary, but your wiz of a teacher will judge you! Judgementally

### 100

What is the biggest difference between the reflection and refraction of light?
What is...reflection is the bouncing of light. Refraction is the bending of light.

### 100

Describe how friction played a positive role in the design of your roller coaster?
What is ...friction slowed the marble down without bringing it to a stop. The kinetic energy was enough that the marble only slowed, thereby increasing the amount of time the marble was rolling. Groups built road bumps, flaps, and barriers to increase friction.

### 100

What is the main difference between speed and velocity?
What is...speed is the measure of how fast something travels (distance over time) while velocity is the measure of how fast something is in a certain direction (ex. 37 mph south)

### 200

What is the term for the rapid back and forth motion of air and other objects?
What is a vibration - that's the creation of sound energy, folks!

### 200

How can a renewable resource run-out, so that we never have it again?
What is ...through poor management of our resources. Overhunting and fishing, killing off of habitat and species within a food web, climate change. I could go on.

### 200

Lily passed a notecard with a secret message on it behind a glass filled with water. The letters appeared much larger behind the water than they did behind just the glass or when you look at the notecard without anything in its way. What is the cause of this "phenomenon" aka science?
What is ...the refraction of light. The water bent the light as it passed through, altering the original image.

### 200

Identify two factors that cause gravity to be stronger between two objects.
What is...the mass of the object (greater mass, greater gravity) and the distance between the objects (less distance, the greater the effect of gravity's pull)

### 200

What type of energy cannot travel through empty space?
What is ...sound energy

### 300

Identify 2 electrical conductors and 2 electrical insulators. Try to vary your responses to show what you know!
What is...any metal, but also water, or fruits that contain acid are conductors. Some even say potatoes are! As for insulators, items like plastics, fabrics, etc.

### 300

Give an example of an inexhaustible resource, as well as one advantage and one disadvantage of its use.
What is...answers will vary, but you have several of these in your i-science notes! Know the answer to this question for 1 of each type of resource!

### 300

Give an example of an object that is transparent, one that is translucent, and one that is opaque.
What is ...transparent? something "see through" like glass; translucent? wax paper; opaque? - a brick wall

### 300

Describe how an electromagnet works using the terms "nail", "wire", and "battery".
What is...a wire is coiled around a nail several times. The ends of the wire are connected to the opposite ends of the battery. The flow of electricity, also known as a current, causes the atoms to realign, creating a temporary magnetic property within the nail. Boom!

### 300

What is the part of an atom that can rub off from one atom to another? It is the reason for a form of energy you use everyday, and you are using right now!
What is ...an electron

### 400

Give an example of an object that uses and produces energy. Briefly describe how it does so and the forms of energy it uses. You must use the word "transform" or a variation of it.
What is ...answers will vary. But think of your toy box. Example - a toaster. Plugs in so it uses electrical energy, which is transformed to produce thermal and radiant energy. Why doesn't it produce chemical energy?

### 400

How does a power plant rely on a magnet to produce electricity? Give details before, during and after the magnets use.
What is ...some resource spins a large magnet, typically by the production of steam that moves a turbine. The spinning magnet can create electricity because magnetism and electricity are closely related. The electricity is then carried to homes via power lines and...TRANSFORMERS! It is definitely more than meets the eye!

### 400

Give an example of 2 objects/tools/technology that reflect light and 2 that refract light. Be specific about which is which.
What is ...reflect -- mirror, sunglasses, tinted glass on a car, some telescopes and microscopes refract -- anything with a lens, some microscopes and telescopes, a prism, a raindrop

### 400

How does mass affect the force of an object? Give a real world, or classroom, example to illustrate.
What is...the greater the mass, the more force is applied. Think the dragon and marble activity. As you increased the marble's mass, the further the dragon was pushed.

### 400

What is the difference between mass and weight? Use "gravity" in your response.
What is ...mass is the amount of matter in an object. Weight is the measure of the force of gravity on an object.

What are the 7 forms of radiant energy as found in the electromagnetic spectrum? An extra $100 if they are in order from highest energy to lowest! What is ...gamma rays, x-rays, uv rays, visible light, infrared, radio waves, and microwaves. Pat yourself on the back if you got that one! ### 500 Describe how fossil fuels are made using the terms, "sediment", "time", "heat", "pressure", and "decay". What is...Animals/plants die. As they become part of the sediment, they decay. More layers of sediment cover them over very long periods of time. Over those millions of years, intense heat and pressure change the once organic matter into a fossil fuel, able to be used for fuel. A nonrenewable resource! ### 500 What role does radiant energy - in this case light AND heat play in the role of climate change? Use "greenhouse", "reflection", "gases" in your response What is...radiant energy strikes the earth. Some is absorbed to heat our oceans and land. Some is reflected back to space. If there are too many gasses in our atmosphere, a greenhouse effect is created. The gasses trap the heat from radiant energy in our atmosphere instead of letting them escape to space, therefore warming our home! ### 500 What form of energy is lost in any energy transformation? AND Energy is neither created nor destroyed, it is only ___________________ (fill in the blank). What is ...thermal (heat) energy. Transformed from one form to another. ### 500 What is the pushing motion of two magnets called? And the pulling? AND....since it's$500, what is the number of waves passing a point in one second called? (yes, this was on your study guide)
What is repelling, attraction, and ...frequency. You need to know all of these terms for your test...guaranteed!!!
