Ralph and Junior were moving a bookshelf across the carpet in their classroom. Even though they pushed as hard as they could, the bookshelf would only move a few centimeters at a time. Which of the following best explains what happened as they tried to push the bookshelf?
When they pushed the bookshelf, the bookshelf pushed back with an equal and opposite force.

While on a camping trip, Briana and Yulliet are traveling in a boat on a river. On their trip, the river's current carries them along at a speed of 5 meters per second (m/s). They do not need to row because the current is carrying them in the direction they need to go. If no other forces are acting on the boat, which of these statements describes the motion of the boat as it travels?
It changes direction
It stays the same.
It slows down.
It speeds up.
Latoya and her friend Dan were playing in the yard at night with flashlights. Each of them observed that as they walked away from each other, the other’s flashlight appeared dimmer. When they walked toward each other, the other’s flashlight started appearing brighter again. When they held their flashlights up side by side, they appeared to be exactly the same size and brightness. They thought that their observations connected to what they were learning about the appearance of stars in the night sky in school. Based on what Latoya and Dan modeled, what would be the best conclusion for them to draw about the appearance of stars in the night sky?
Two similar-sized stars may vary in brightness when viewed from Earth.
All stars are the same brightness and the same distance from Earth.
All stars are the same size, but do not give off equal amounts of light.
Two stars of different sizes may be of equal brightness.
Around seven o’clock one evening, Son'jai observed a pattern of stars, called Orion, in the night sky. Three hours later he went outside to show his parents that same pattern of stars. What would he notice about the pattern of stars after three hours?
The pattern of stars would appear to be in the same place in the sky.
The pattern would be smaller because the stars moved closer together.
The pattern of stars would appear to have moved together across the sky.
The pattern would change because each star would have moved in a different direction.
Haven and T'yonna are comparing two samples of matter. They make a table of the properties of each sample. Which property provides the best evidence that both samples are solids rather than liquids?
volume
mass
color
shape
Ysmelene and Rosalinda wanted to find out which material would insulate their teacher's coffee cup and keep the coffee hot for the longest period of time. They first wrapped her cup with bubble wrap and recorded the temperature of the coffee once every 15 minutes for 2 hours. They repeated the investigation, this time using newspaper instead of bubble wrap, but they got the same results for both materials. What could they do to make sure their results are valid?
Conduct their investigation in a colder room.
Use a different thermometer.
Repeat their investigation.
Use tea instead of coffee.
