 * Let's SRE this together:**

Gino is designing an investigation to see what happens to the motion of a wood block as it moves across different surfaces. He uses a spring scale, a block of wood, and pieces of four different surfaces to drag the wood across. =====

D. The investigation can be changed by others to get different results.
Tess was conducting an experiment with two balls of different masses. She lined the two balls up on the floor along a ruler. Then she pushed the ends of the ruler forward so the ruler pushed the balls at the same time with the same amount of force. Why did Tess use the ruler to push the balls?
 * Now you try it with this one:**

A. She wanted to make sure the balls rolled the same distance to show that mass doesn't have an effect. B. She wanted to be sure the balls received the same force to see if mass has an effect on distance the balls traveled. C. She didn't want to waste any time by giving two balls two separate pushes. D. She only had one ruler.

Brian and Emily are testing different paper airplane designs to see which will allow a plane to go the farthest. Emily folds her plane and attaches a paperclip to the front of it. After she throws the plane, it travels about fifty feet and then starts to fall to the ground.
 * Let's SRE This together:**

Why does the plane eventually fall to the ground?

A. The force of wind resistance shortened the flight. B. The plane was not designed to hold the mass from the paperclip. C. The force of gravity is stronger than the force keeping the plane in the air. D. The paperclip creates a magnetic force that attracts the plane to the ground.

Mya is playing with a soccer ball at the top of a hill. Mya kicks the ball and it rolls down the hill where is eventually stops. Which of the following best describes what happens as the ball rolls?
 * You Try it: **

A. The forces acting on the ball and t he force of gravity pulls the ball downhill. B. The force of friction causes the ball to roll faster down the hill. C. The force of gravity is balanced by air resistance acting on the ball. D. The force of friction is greater than the force of gravity acting on the ball.

 * Let's SRE this together: **

Sir Issac Newton experimented and found outh that because the force of gravity is so strong, it appears to attract all objects equally, regardless of mass. Which of the following is illustrated by this idea?

A. Earth orbits the Sun in the same amount of time it takes the Moon to orbit Earth. B. A rubber ball will bounce much higher than a wooden ball, even if they weigh the same. C. Magnets can both repel and attract each other, depending on how they come into contact. D. A bowling ball and a peanut will fall to the ground at the same rate when someone drops them.

People riding the Demon Drop fall faster than the people riding on the parachute ride. Which of the following explains why a parachute makes a person falling from a great height fall more slowly?
 * Now you try it! **

A. The parachute reduces the friction in the air. B. The parachute pulls upward, so the fall is slower. C. The parachute causes air resistance, which slows the fall. D. The parachute decreases the pull of gravity on the person wearing it.

To help Mrs. Driver, Aaron and Isaiah were moving a bookshelf across the carpet in the library. Even though they see themselves as very stong, they pushed as hard as they could but the bookshelf would only move a little bit at a time. Which of the following **best** explains what happened as they tried to push the bookshelf?

A. Because we are so close to the equator, the force of gravity opposed the motion of the bookshelf. B. Because of the carpeting in the library, t he force of friction opposed the motion of the bookshelf. C. When they tried to push the bookshelf, air resistance acted against them. D. When they pushed the bookshelf, the bookshelf pushed back with an balanced and opposite force.


 * Now you try it!**

Marquis and Tyrell are playing tug of war during PE. Coach called, "Ready, Set, Go!" As they both began pulling, they immediately noticed that neither of them were going to win. No matter how hard they pulled, the flag at the center of the rope didn't move. Why is it that neither of them are winning?

A. Marquis is applying an unbalance force in one direction. B. Tyrell is applying an unbalance force in one direction. C. Marquis and Tyrell are applying balanced forces in the same direction. D. Marquise and Tyrell are applying balanced forces in opposite directions.
