Science Glossary Unit Two

Question 1

Burn Scar

Answer 1

Land previously burned and damaged by a forest fire.

Question 2

Zombie Fire

Answer 2

Forest fires in the fall that burn underground during winter and resurface in the spring.

Question 3

Fuel

Answer 3

A mass of matter that is flammable and contains energy

Question 4

Energy

Answer 4

Flows through a system once, dissipates as heat.

Question 5

Matter

Answer 5

Cycles through ecosystems.

Question 6

Cellular Respiration

Answer 6

Process of converting energy and matter from fuel to usable energy and other products.

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 36 ATP energy

Question 7

Anaerobic Respiration

Answer 7

Ability to break down energy without an oxidant.

1. Anaerobic Respiration yields way less energy than aerobic respiration.
2. Glucose → 2 ATP energy

Question 8

Carbon Sink

Answer 8

Large storage of carbon that keeps carbon out of the atmosphere

Question 9

Photosynthesis

Answer 9

Using light to create chemical energy.

The plants that photosynthesize support the whole system.

6CO₂ + 6H₂O → (energy) C₆H₁₂O₆ + 6O₂
Photo meaning light (ie. photon, photography, etc), and synthesis meaning to create.

Question 10

Directional Hypothesis

Answer 10

A proposed explanation for the relationship between two variables in a phenomenon.

Question 11

Chemical Energy

Answer 11

Artificially made energy made by the conversion of one molecule to another.

Light energy → Chemical energy
