Why do all the stars look like small points of light in the night sky?

• Because stars like to give us light

• Because stars give off light energy and are very far away

• Because stars are actually lights created by the government to give us light

• Because aliens

A skydiver jumps out of a plane. He falls downward at a very fast speed. When he opens his parachute, he slows down. He falls at a safer speed until he lands. What force pulled skydiver to the ground?

In baseball, a fly ball happens when a player hits the ball high into the air. The player on the other team must wait for it to come down to catch it. Imagine that there was suddenly no gravity. How would the ball be different?

• The ball would shoot out to space

• The ball would light on fire

Ms. Parson is holding some books. Why doesn't gravity pull the books to the floor?

• Ms. Parson is holding the books with a force equal to the force of gravity pulling the books down.

• Ms. Parson is mad strong, yo

• Ms. Parson is using a force greater than that of the gravity.

• This is impossible

Two scientists are studying how gravity affects objects in different cities. One scientist finds that a baseball drops to the floor in 5 seconds. The other scientist finds the same thing in her city. Why is it important for these scientists to share their findings?

• The scientists need to compare their data to better understand gravity

• So the scientists can go home and take a nap

• Because then they can finally stop studying gravity

• Because they need to know that everything on earth is exactly the same.

Jenny put a flashlight on a table so the light shined on a wall. She put a piece of cardboard in front of the flashlight and could no longer see the light on the wall. What most likely happened to the light when it reached the cardboard?

• It bends

• It reflects

• It is absorbed

Lillian placed red and black paper on the sidewalk. She placed a thermometer on each piece of paper. She then recorded the temperature every 2 minutes. What is the best way to keep a record so she can compare the temperatures later?

• Create a drawing of the experiment

• Create a graph of the temperatures

• Create a list of the hourly temperatures in her neighborhood

• Create a data table for the two colors and record the temperatures every two minutes
