(2) Mrs. Giet’s class is playing tug of war at recess. They decide to play boys against girls. There are 11 girls and 6 boys. As soon as the game began, the girls were able to move the rope to their side. Why?
There was an equal amount of force pulling on each side making it unbalanced.
There was an equal amount of force pushing on each side making it unbalanced.
There was more force on the girls side making it unbalanced.
There was less force on the girls side making it unbalanced.
Which of the following would it take the most force to move?
a 3-pound ball
a 5 pound ball
a 15 pund ball
a 25 pound ball

6.8D- During a science experiment, a student dropped a metal ball from a height of 150 m. The graph shows the distance the metal ball traveled from its initial position to where it hit the ground.
What information does the graph give you about the speed of the metal ball over time?
The ball travels at a constant speed.
The speed of the ball increases over time.

One morning, a student notices that the grass in the area is wet, although it had not rained during the night. What could have caused the grass to be wet?
During the night, water had evaporated from the trees in the area.
The air above the ground became warmer during the night and caused precipitation.
When the air cooled above ground during the night, water vapor condensed on the grass.
The grass soaked up water from the ground during the night.
