Physical/Chemical Changes
Who's That Guy Newton?
Forces
Energy
100
This is the definition of matter
What is anything that takes up space and has mass?
100
This is the difference between a chemical and physical change.
What is in a physical change the item remains the shame item just size or shape may change? What is in a chemical change the atoms reconnect to form something new?
100
This is what Sir Isacc Newton is best known for.
What is his laws of motion?
100
This pair of forces would cause two marbles to roll away from each other at the same speed after colliding.
What are balanced forces?
100
This defines potential energy.
What is stored energy waiting to be released?
200
The two ways to measure the volume of matter
What is measuring a prisms length, width, and height and then multiplying them or placing an odd shaped item in water and measuring how much the water went up? (water displacement)
200
This one is a physical change: burning wood, baking a cake, the wax on a candle melting, hydrogine peroxide on a cut.
What is the wax on a candle melting?
200
This is Newton's first law of motion and an example of it.
What is an object at rest will stay at rest and an item in motion will stay in motion unless a force acts upon it? (examples could be: person with seatbelt on, kicked ball, a parked car, etc.)
200
This pair of forces would explain what happens to a car after colliding with a garbage truck.
What are unbalanced forces?
200
This explains energy in motion.
What is kinetic energy?
300
Under a microscope, this is how the molecules look in a gas
What is spread apart and moving fast?
300
If you chop wood, shred a newspaper, pop popcorn, and break a mirror, this one would you be causing a chemical properties to change. Explain why.
What is popping popcorn because the heat causes the kernals to change properties and turn into something new?
300
This explains why when one domino falls against another, it falls and the rest continue to fall.
What is Newton's Third Law. For every action, there is an equal and opposite reaction.
300
This explains the force needed to move a golf ball compared to a bowling ball.
What are objects with more mass need more force to move them?
300
This describes a combination of two types of energy that does work.
What is mechanical energy?
400
Name three ways to speed up the dissolving of sugar in water.
What is stirring it, warming the water, and placing the sugar as granuales rather than a cube?
400
Name both a physical and chemical change that an apple could go through.
What is cutting it, making it into applesauce (physical); digesting it, making pie out of it (chemical) or any other acceptable ideas?
400
This is why an object accelerates.
What is Newton's Second Law. This occurs when a force increases the velocity of an object.
400
This explains why you don't fall to the ground while seted in a chair.
What are balanced forces, gravity pulling on you and the chair pushing up on you?
400
This describes what actually happens to light energy when it refracts.
What is the light passes through clear materials, and bends because the speed of the light changes?
500
These are the different ways in which you could separate a mixture of paper clips, sand, and marbles.
What is a magnet, a sift strainer, and your fingers.
500
This is what happens to the atoms in an items that have undergone a chemical change.
What is the atoms link up differently forming a new substance?
500
This force cause an object to slow its velocity and decelerate.
What is friction?
500
This explains why a football flies through the air after being kicked.
What is Newton's Second law? (the force of the kicker's foot increased the velocity of the football)
500
This explains how chemical energy changes into mechanical energy.
What is food is digested releasing it's chemical energy and allowing muscles to do work (mechanical) by moving the human body. Other examples may be acceptable.
