Matter
This describes anything that has mass and takes up space.
What is matter?
This is the ability to do work or cause change.
What is energy?
A push or a pull that can change an object’s motion is called this.
What is a force?
This wave requires a medium
What is a mechanical wave?
This material easily allows the flow of heat or electricity while this material doesn’t easily allow the flow of heat or electricity.
What are conductors and insulators?
This state of matter has particles tightly packed together
What is a solid?
A roller coaster climbs a tall hill and then speeds down into a loop.
What energy is transformed during this motion?
What is potential to kinetic energy?
An object at rest will stay at rest, or an object in motion will stay in motion unless a force is applied to it.
What is Newton's 1st Law?
This electromagnetic wave is used in medical imaging
What are x-rays?
Every magnet has these two regions where the magnetic force is strongest.
What are magnetic poles?
Changes like melting or freezing affect only the form of matter, not what it is made of.
What are physical changes?
A student rides a battery-powered electric scooter to school. As the scooter moves, the wheels turn, and the headlight turns on. These are the energy transformations that are occurring.
What is chemical energy → electrical energy → mechanical energy and light energy?
In this example, two students are pushing opposite sides of a box. Student A pushes with 50 N of force to the right, and Student B pushes with 30 N of force to the left. The box begins to slide to the right.
What is unbalanced forces?
This wave behavior is responsible for the image of the sky appearing on the surface of a lake
What is reflection?
Charging objects through rubbing is called this.
What is friction?
You get this mixture when a student mixes sugar into hot tea and observes that it dissolves completely, forming a clear liquid.
What is a homogeneous mixture?
These two factors affect kinetic energy.
What is speed and mass?
A student pushes two toy cars with the same force. One car is heavier than the other. This car will accelerate more.
What is the lighter car?
Sound travels through air, glass, and water. List these materials from fastest to slowest in terms of sound speed.
What is Glass, Water, Air?
When an electric current flows through a wire, it creates a magnetic field around the wire, showing that electricity and magnetism are directly connected.
What is electromagnetism?
In a closed system, a student mixes vinegar and baking soda and measures the total mass before and after the reaction and demonstrates this law.
What is the law of conservation of mass?
A student touches a metal spoon that was sitting in a bowl of hot soup and notices it feels warm.
Which type of heat transfer occurred?
What is conduction?
In an example of this law, a rocket is launched into space. As it blasts off, hot gases are pushed downward out of the engines, and the rocket lifts upward into the sky.
What is Newton's 3rd Law?
Two medical imaging tools are being compared:
- One uses infrared waves to detect heat from the body.
- The other uses X-rays to see inside the body and examine bones.
This wave carries more energy.
What are x-rays?
This process occurs when a changing magnetic field induces an electric current and is the principle behind generators and transformers.
What is electromagnetic induction?
