100
What force pulls objects toward Earth?
Gravity
100
What type of energy is stored energy?
Potential Energy
100
What type of wave is a sound wave?
Mechanical Wave
100
What layer of Earth do we live on?
Crust
100
What is the basic unit of life?
A Cell
100
What are the two ends of a magnet called?
Poles (north and south)
100
What is the variable that is changed on purpose in an experiment?
independent variable
100
What is matter?
Anything that has mass and takes up space
100
What is the relationship between force and acceleration? Use evidence from the table.
As force increases, acceleration increases. The data shows that doubling the force doubles the acceleration, indicating a direct relationship.
200
What is the measure of how fast something moves in a certain direction?
Velocity
200
What energy transformation occurs in a flashlight? (3 things in order)
Chemical → electrical → light
200
What part of a wave is the highest point?
Crest
200
What causes seasons on Earth?
Earth's tilt
200
What structure controls cell activities?
Nucleus
200
What happens when two like magnetic poles are brought together?
They repel
200
What is the variable that is measured or observed?
dependent variable
200
What are the three common states of matter?
Solid, Liquid, Gas
200
A roller coaster starts at the top of a hill and moves down.
Explain how energy changes as the coaster moves down the hill.
Gravitational potential energy decreases while kinetic energy increases. Energy is conserved but changes form.
300
An object at rest will stay at rest unless acted on by what?
An unbalanced force
300
What law states energy cannot be created or destroyed?
Law of Conservation of Energy
300
What happens to wavelength when frequency increases?
Wavelength Decreases
300
What type of boundary forms mountains?
Convergent Boundary
300
What is it called when organisms better suited to survive reproduce more?
Natural Selection
300
What is the region around a magnet where magnetic forces act?
Magnetic field
300
What are the three parts of a CER response?
Claim, Evidence, and Reasoning
300
What happens to particles when matter is heated?
They move faster and spread apart
300
A wave has a high frequency and short wavelength.
What can you conclude about the wave’s energy and why?
The wave has higher energy because higher frequency waves carry more energy.
400
What happens to acceleration if mass increases but force stays the same?
Acceleration decreases
400
What happens to thermal energy when particles move faster?
It increases
400
What type of wave can travel through empty space?
Electromagnetic Wave
400
What process breaks down rock at Earth’s surface?
Weathering
400
What do all living things need to maintain stability?
Homeostasis
400
How can you increase the strength of an electromagnet?
Increase current, add more coils, or use a stronger core
400
What should you keep the same in an experiment to make it fair?
controlled variables (constants)
400
What is the difference between a physical change and a chemical change?
Physical = no new substance, Chemical = new substance forms
400
A student tests plant growth but changes both sunlight and water at the same time.
What is wrong with this experiment and how can it be fixed?
There are multiple independent variables. Only one variable should be changed at a time while others are controlled.
500
A car doubles its speed. What happens to its kinetic energy?
It increases (quadruples)
500
Why are energy transfers never 100% efficient?
Some energy is lost as heat
500
How does amplitude relate to sound?
Greater amplitude = louder sound
500
Why do coastal areas have milder climates?
Waters heats and cools slowly
500
What evidence shows species share a common ancestor?
Similar body structures (homologous structures)
500
What happens to the potential energy in a magnetic system when two attracting magnets are pulled apart?
The potential energy increases
500
A graph shows temperature increasing over time. What does the slope of the graph represent?
The rate of change (how fast temperature is increasing)
500
What evidence shows a chemical reaction has occurred?
Color change, gas production, temperature change, or precipitate forms
500
Two species have similar bone structures in their limbs but live in different environments.
What does this suggest about their evolutionary history?
They share a common ancestor. The similar structures (homologous structures) are evidence of evolution from the same origin.
