Astronomy and Space Science
What model of the solar system did Galileo's observations of Venus support?
Heliocentric model.
Why are astronomical units (AU) used to measure distances in space instead of kilometers?
Because they make the vast distances more manageable and understandable.
What is the approximate surface temperature of the Sun, based on its yellow color? (Pg. 81)
6,000 – 7,500 K
What changes occur to food in the mouth during eating?
Food is physically broken down by chewing and chemically broken down by saliva.
What is the primary process by which carbon is recycled in the ecosystem, involving the conversion of CO2 into organic compounds by plants?
Photosynthesis
During a coast-to-coast solar eclipse in the United States, how are the sun, the moon, and Earth arranged?
The moon was between Earth and the sun.
Which celestial body has the greatest effect on ocean tides on Earth?
The Moon, due to its proximity to Earth.
Which state of matter has particles that are close together but can slide past each other?
Liquid
Which model of the atom shows electrons in specific orbits around the nucleus? (Pg. 198)
Bohr’s model of the atom
What kind of chemical reaction involves one element replacing another in a compound?
Replacement reaction
Why is it much colder in Michigan than in Florida during the winter?
Earth’s tilt away from the sun during the winter causes Michigan to receive less direct sunlight than Florida.
What type of mixture is river water if it contains dissolved minerals but appears clear?
Solution
What happens to the pressure inside a sealed container if the temperature increases but the volume stays the same?

What are the visible signs that show a chemical change has occurred in baked cake batter?
Change in color and gas given off.
What type of reaction is occurring when copper reacts with silver nitrate to produce silver and copper(II) nitrate?
Replacement reaction
What is the final stage in the life cycle of a star like our Sun?
White Dwarf
(Life cycle of stars: nebula → protostar → high-mass star → red giant→ planetary nebula → white dwarf or nebula → protostar → low-mass star → supergiant → supernova → white dwarf)
How does the removal of forests impact the carbon cycle on Earth?
It reduces the amount of carbon dioxide that is removed from the atmosphere by photosynthesis.
Which chemical equation correctly describes the formation of aluminum oxide (Al2 O3) from aluminum (Al) and oxygen (O2)?
4 Al + 3 O2 → 2 Al2O3
Name two elements that would likely have similar properties based on their position on the periodic table
Answers will vary ex: Li and Na, N and O, He and Ne, etc.
What is the simplest type of pure substance, and what is its smallest unit?
An element, and its smallest unit is an atom
What is the correct term for a streak of light in the sky caused by a small object burning up in the Earth's atmosphere?
