Matter & Energy
This tool organizes elements and helps identify which atoms participate in chemical reactions.
periodic table
This law explains how acceleration increases when net force increases and decreases when mass increases.
Newton’s Second Law of Motion
This measures how many wave cycles pass a point in one second.
frequency
This diagram is used to classify stars based on their brightness and temperature.
Hertzsprung-Russell (H-R) diagram
This type of ecological succession occurs when an ecosystem is rebuilt after a disturbance where soil is already present, like a forest fire.
secondary succession
This scale measures how acidic or basic a substance is compared to water.
What is the pH scale
If the same force is applied to two objects, the object with more of this will accelerate less.
mass
This is the distance between two matching points on consecutive waves, such as crest to crest
wavelength
Where is our sun located in the milky way Galaxy?
On the arm
This increases an ecosystem’s ability to recover from changes and helps maintain stability.
biodiversity
This property allows water molecules to stick to each other, helping insects walk on water.
surface tension
This is the overall force acting on an object after all forces are combined.
net force
These waves have the shortest wavelength and highest frequency in the electromagnetic spectrum.
gamma rays
These powerful storms form over warm ocean water when warm, moist air rises and rotates due to Earth’s spin.
hurricanes
This part of the cell controls what enters and leaves the cell.
cell membrane
This type of mixture has substances that are evenly distributed and look the same throughout.
homogeneous mixture
This law explains why passengers continue moving forward when a car suddenly stops.
Newton’s First Law of Motion
This part of the electromagnetic spectrum has longer wavelengths than visible light and is commonly used for communication signals like TV and radio.
radio waves
This activity removes trees, reducing carbon dioxide absorption and increasing greenhouse gases.
deforestation
This is a section of DNA found on chromosomes that determines inherited traits, such as eye color or height.
gene
This law states that matter cannot be created or destroyed during a chemical reaction.
law of conservation of mass
This law explains why a rocket moves upward when gases are pushed downward with equal and opposite force.
Newton’s Third Law of Motion
This is the height of a wave from its rest position and is related to the energy it carries.
amplitude
This type of star is very hot, very bright, and appears in the upper left of the H-R diagram.
blue giant
This organelle is known as the “powerhouse of the cell” because it produces energy.
mitochondria
