Matter & Molecules
This state of matter has a definite shape and volume.
These organisms get their energy by eating other plants or animals.
Consumers
Does the Sun move around the Earth, or does the Earth rotate?
The Earth rotates around the sun.
Everything in the universe is made of these tiny particles.
Atoms.
This type of energy is the energy of motion.
Kinetic Energy.
When a solid turns into a liquid, it is called this.
Melting
This is the primary source of energy for almost all food webs.
The sun.
This force pulls objects toward the center of the Earth.
Gravity.
When two or more atoms bond together, they form this.
Molecules.
Sound travels in these, which require a medium to move through.
Waves.
This is the name for the process where a gas turns back into a liquid.
Condensation
These organisms, like fungi, break down dead matter into nutrients.
Decomposers.
This is the reason we see different constellations at different times of year.
Earth's orbit around the sun.
A "mixture" where one substance is dissolved into another.
A solution.
This term describes how many waves pass a point in one second.
Frequency.
True or False: Air has mass and takes up space.
True.
This is the specific part of the plant where photosynthesis happens.
Chloroplasts.
This is the term for the invisible line Earth rotates around.
Axis.
This happens when molecules rearrange to form a brand new substance.
A chemical change.
When light bounces off a surface, it is called this.
Reflection.
This property of matter describes how much "stuff/matter" is in a given space.
Density
These are the three things plants need to perform photosynthesis.
Sunlight, Water, Carbon-Dioxide.
This is the reason the Moon appears to change shape over a month.
Moon Phases. (Caused by the moon's position relative to Earth/Sun).
This scientific law states that during a chemical reaction, matter cannot be created or destroyed, meaning the total mass of the reactants must equal the total mass of the products.
Law of Conservation of Mass.
This is the distance between the peak of one wave and the next.
Wavelength.
