A room has an electric heater on one side. Which explanation best predicts the air movement pattern you would observe?
Warm, less dense air rises and cooler, denser air sinks

Fastest in steel, slower in water
Fastest in air, slower in water
Fastest in water, slower in steel
Same speed in all materials
A student increases the frequency of a wave on a slinky while keeping amplitude the same. What happens to the wave’s energy?

Sound travels fastest in solids
Sound travels fastest in gases
Sound speed is identical in all
Sound cannot travel through solids
You compare two drawn waves. Wave X shows widely spaced crests; Wave Y shows closely spaced crests. Which has the longer wavelength?
Wave X has the longer wavelength
Wave Y has the longer wavelength
They have equal wavelengths
Wavelength cannot be compared
Which statement correctly describes the basic orbital relationships in our solar system?
The Moon orbits the Earth, and Earth orbits the Sun
The Sun orbits Earth, and Earth orbits the Moon
Earth and Moon both orbit the Sun directly
The Moon and Sun both orbit around Earth
What primarily causes the seasons on Earth?
Earth’s tilt combined with its revolution around the Sun
Changes in the distance between Earth and the Sun
Monthly changes in the Moon’s phase
Daily rotation of Earth around its axis
In the Northern Hemisphere, why are summer days longer and warmer?
The hemisphere tilts toward the Sun, receiving more direct rays
The Moon blocks sunlight less often during summer months
Earth moves closer to the Sun in its elliptical orbit
Cloud cover decreases due to seasonal wind changes
Which description best explains waxing versus waning of the Moon?
Waxing gets brighter with increasing lit fraction; waning gets darker
Waxing is darker with less light; waning grows brighter each night
Waxing occurs only at full moon; waning only at new moon
Waxing happens when Earth’s shadow covers the Moon
A solar eclipse can only occur during which lunar phase and why?
New Moon, because the Moon can pass between Sun and Earth
Full Moon, because Earth is between the Sun and Moon
First Quarter, because the Moon is at right angles
Third Quarter, because the Moon shows half its lit side
During a lunar eclipse, what is the alignment of the three bodies?
Sun–Earth–Moon with Earth’s shadow on the Moon
Sun–Moon–Earth with the Moon blocking sunlight
Earth–Sun–Moon with sunlight bent by Earth
Moon–Earth–Sun with the Sun eclipsed by Earth
A student claims seasons happen because Earth is sometimes closer to the Sun. What evidence-based correction should you give?
Seasons result from Earth’s axial tilt changing sunlight angle
Seasons occur from monthly moon phases altering sunlight
Seasons are caused by Earth spinning faster in summer
Seasons happen when the Sun’s brightness varies yearly
Which statement best describes an independent variable in an experiment?
The factor the scientist intentionally changes
The factor that stays constant for fairness
The measurement recorded after a trial
The average calculated from the data
In a tomato experiment, a scientist varies fertilizer amount. What is the dependent variable to measure?
Size of the tomatoes
Type of fertilizer used
Schedule of watering plants
Presence of sunlight each day
A student tests sugar in water: some cups have sugar, some do not. Which is the independent variable?
Presence of sugar in the water
Growth of the plants over weeks
Size of leaves on each plant
Mean height calculated later
You collected heights of plants over time. What is the best first step to analyze the data?
Organize into charts and graphs
Add more independent variables
Change the measurement units
Ignore outliers without checking
Data show that as fertilizer amount increases, tomato size increases up to a point, then decreases. Which conclusion is most reasonable?
There is an optimal fertilizer amount
Any fertilizer always increases size
Fertilizer is not a variable at all
Mean size must be identical always
Which statement best describes the relationship between orbital period and orbital distance for objects orbiting the Sun?
Shorter period means farther from the Sun
Longer period means closer to the Sun
Longer period means farther from the Sun
Period stays the same for all planets
An object takes 225 Earth days to orbit the Sun. Compared to Earth, how is its distance from the Sun ranked?
Closer than Earth in distance
Farther than Earth in distance
Equal to Earth in distance
Cannot be determined from period
Use the data: W = 225 days, X = 687 days, Y = 365 days, V = 59,800 days, Z = 90,560 days. Which object is farthest from the Sun?
X has the greatest distance
Z has the greatest distance
W has the greatest distance
Y has the greatest distance
Using the ranking strategy, order the objects from closest to farthest: W = 225, X = 687, Y = 365, V = 59,800, Z = 90,560. What is the correct first three?
W, Y, X are first three
Y, W, X are first three
W, X, Y are first three
X, W, Y are first three
A new object P has an orbital period of 450 Earth days. Where would P fit among W = 225, Y = 365, X = 687?
Between W and Y in rank
Between Y and X in rank
Before W in rank
After X in rank
Two objects have periods of 59,800 days and 90,560 days. What reasoning supports which one is farther?
Smaller period means greater distance
Greater period means greater distance
Equal period means equal distance
Period is unrelated to distance
Which statement best defines atomic number for an element?

Total electrons orbiting in outer shells
Total protons in the atom’s nucleus
Sum of protons and neutrons together
Where are protons, neutrons, and electrons typically located within an atom?

Protons in shells, neutrons in nucleus, electrons in nucleus
Protons in nucleus, neutrons in shells, electrons in nucleus
An atom has 8 protons, 8 neutrons, and 8 electrons. What is its atomic number?
8 because atomic number equals protons
16 because protons plus neutrons
24 because all subatomic particles
0 because charges cancel overall
A neutral atom loses one electron. Which change is most accurate?
Its atomic number decreases by one
It becomes a positive ion overall
Its neutron count increases
Its protons move into the shells
