Inspire Science Unit 4a Lesson 1 (Gravity)

Why can Juanita and Clara stand with their feet on the ground at the North Pole and South Pole, respectively?

• Because the Earth is flat

• Because gravity only works at the poles

• Because gravity pulls them towards the center of the Earth

• Because they are wearing special shoes

Things we drop fall to the ground because __________ pulls them down.

• friction

• gravity

• magnetism

• electricity

Which explains how gravity works to assist the flight of an airplane?

• It pushes up on the wings of the airplane to create lift.

• It helps to propel the plane forward as its speed increases.

• It pushes the airplane from all directions to help it stay in the air.

• It pulls the airplane downward when the pilot slows the engine's speed.

In science class, Simon learned that he weighs 90 lb on Earth and 15 lb on the Moon. Explain why there is a difference in Simon's weight in the two different locations.

• The Moon has more gravity than Earth.

• The Moon has less gravity than Earth.

• Simon's mass changes between Earth and the Moon.

• The Moon and Earth have the same gravity.

Which would be the most likely outcome of a meteorite's encounter with Earth?

On the moon, craters are formed when ______ hit the surface.

• meteoroids

• comets

• asteroids

• satellites

How can Brianna explain to Clayton the process by which space rocks become meteors and meteorites?

• Space rocks are captured by Earth's gravity and become meteors when they burn up in the atmosphere; those that land on Earth are called meteorites.

• Space rocks spontaneously combust and turn into meteors; the remnants that reach Earth are known as meteorites.

• Space rocks are ejected from the moon and become meteors; meteorites are the pieces that get caught in Earth's orbit.

• Space rocks are remnants of comets that turn into meteors; meteorites are the ones that escape Earth's gravitational pull.
