What two things are wrong about this model of the solar system?
The planets are too big
The planets are too close together
The planets are out of order
The Sun is too big
Our solar system is made up of the Sun, 8 planets, and other bodies such as asteroids orbiting the Sun. The solar system is very large compared to anything we see on Earth. The distance between planets is measured in astronomical units (AU). One AU is equal to 149.6 million kilometers, the average distance between the Sun and Earth. Scale models are useful for helping us understand the size of the solar system.
Mr. Rohm's science class made a scale model of the solar system. They went out to the school’s football field, and they used the chart shown below to mark out the scale distance from the Sun to each planet.
Choose the most correct answer about what the model of the solar system on the football field shows.
the model shows the distances of the planets compared to each other
the model shows the size of the planets compared to each other
the model shows the composition of the planets compared to each other
the model shows none of the above

Predict what would happen to the tidal range if the Moon were twice as far from Earth.
The tidal range would decrease because the Moon's gravitational pull would be weaker.
The tidal range would increase because the Sun's gravity would have a greater effect.
The tidal range would stay the same, but the number of daily tides would change.
Tides would cease to exist altogether.
Predict what would happen to the tidal range if the Moon were twice as massive.

During a full moon, the Sun, Earth, and Moon form a straight line. What is the combined effect of the Sun's and Moon's gravity on Earth's oceans at this time?
Their gravitational forces combine, leading to a spring tide with a large tidal range.
Their gravitational forces counteract each other, leading to a neap tide with a small tidal range.
Only the Moon's gravity affects the tides.
The tides are average and have no special characteristics.
What is the tendency of an object to resist a change in motion?
coffee
motion
inertia
gravity
Jane was standing inside a bus when the bus suddenly started moving. She immediately lost her balance and stumbled toward the back of the bus. This happened because
Jane was standing in the back of the bus
Jane was at rest and her body resisted a change in its motion
Jane was walking through the bus
the force of gravity was greater than the force of the moving bus
A person would weigh less on on the Moon than on the Earth because . . .
Moon has more mass, and therefore more gravity

Model A
Model B
Both Model A and Model B (same gravity)
Earth
Mars
Mercury
What would be true of weight if you went to Mars?
