All matter is made of these. When these combine, they make molecules and/or compounds.
What are atoms? Elements is acceptable too, since each element is made up of one kind of atom.

This would be the sequential steps, or order, through the digestive system. Use these 7 terms: stomach, large intestine, toilet, small intestine, mouth, colon, esophagus.
What is 1-mouth, 2-esophagus, 3-stomach, 4-small intestine, 5-large intestine, 6-colon, 7-toilet?

These vascular "tubes" in plants pull water up from the roots
What are xylem?
200
This is when a liquid changes into a gas.
What is evaporation?

This object would be a rock that generally stays between Mars and Jupiter, but sometimes it comes flying through our atmosphere and hits our planet.
What is an asteroid? Meteor and meteorite are acceptable too.
300
This is a change in a substance that regroups the atoms to make a new substance with different chemical properties. For example, baking a cake, burning something, popping popcorn.
What is a Chemical Change or Reaction?

These would be the two blood vessels that circulate blood throughout your body and the type (oxygen rich or oxygen poor) of blood they carry.
What are veins, which carry oxygen-poor blood back to heart and arteries, which carry oxygen-rich blood away from heart?
300
The process by which plants make their own food by using carbon dioxide and energy from sunlight to build molecules of sugar and release oxygen.
What is photosynthesis?

This is when a gas changes back into a liquid. Clouds would be an example of this...
What is condensation?
300
The two elements / atoms that primarily make up our sun and all stars.
What is hydrogen and helium?

These are four indicators of a chemical change or reaction.
What is color change, gas produced, temp. change, new substance?
400
These would be the two gases that are exchanged in the lungs.
What are carbon dioxide and oxygen?

This would be four types of precipitation.
What is rain, snow, sleet, and hail?

This is the invisible force that keeps you on planet Earth, moons revolving around planets, the planets revolving around the sun, the solar system revolving around galaxy, etc.
What is gravity?
500
This is a mixture of metals, and therefore not a pure element. Some examples might be steel, brass, or bronze.
What is an alloy?
500
These are the tiny compartments of life that make up all living organisms, including the description of the general shape of plant and animal types.
What are cells? Animal cells are usually circular or oval, whereas plant cells are square or rectangle.

This gas is what plants use or need to drive photosynthesis. It is odorless and colorless, and it is the waste gas of animals.
What is carbon dioxide?
500
This would describe air pressure high in the atmosphere. For example, the air pressure would be ________ in the mountains, when compared to sea level.
What is lower pressure?
500
This is essentially a dirty snowball, made of ice and rock. It has an enormous orbit, usually going way, way, way, past Pluto and then sometimes coming in close to the sun where it can be observed from Earth. They usually have a "tail" from the ice/water evaporating.
