100
It has four "spheres"
How many spheres does the Earth have?
100
Colorless, odorless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air
What is Oxygen? 
100
Characteristics that can be determined without changing the composition of the substance.
What are Physical Propeties?
100
(Pure Substance/Mixture)
Water
Water is a Pure Substance?
200
Abiotic
What is Non-living?
200
The energy-rich substance that is produced by green plants during photosynthesis
What is Sugar?
200
Describe the ability of a substance to change its composition to form new substances.
What are Chemical Properties?
200
The state of being thick, sticky, and semifluid in consistency, due to internal friction.
What is Viscosity?
300
Biotic
What is Living?
300
The highest trophic level on a food chain
What is the 4th trophic level?
300
Special Question: True or False?
Particles Attract Each other
True!
300
Anything composed of a single type of material.
What is a Pure Substance?
400
A biological community of interacting organisms and their physical environment
What is an Ecosystem?
400
Is a chemical process in which energy is released from food. In this process, the sugar and oxygen are rearranged to form carbon dioxide and water. As this reaction takes place, energy is released. The plant is able to use this released energy for any of the activities carried out by its cells.
What is Cellular Respiration?
400
Tin and lead are pure metals. Each metal by itself is a pure substance because it is made of only one type of particle. When two or more metals are mixed together.
What is an Alloy?
400
A substance made by mixing other substances together.
What is a Mixture?
500
The chemical energy used by organisms comes from here (The earth orbits around this star)
What is the Sun?
500
Most producers use light energy to convert two low-energy chemical compounds (carbon dioxide and water) into high-energy compounds (sugars). In doing so, they release oxygen gas into the environment as a by-product.
What is Photosynthesis?
500
They are all odorless, colorless, monatomic gases with very low chemical reactivity. The six naturally occurring are helium, neon, argon, krypton, xenon, and the radioactive radon.
What are Noble Gases?
500
A pure substance that cannot be broken down into a simpler chemical substance by any physical or chemical means
What is an Element?
