David and Delia will not move because their forces are unbalanced.
David will move up, and Delia will move down because their forces are unbalanced.
David will move down, and Delia will move up because their forces are unbalanced.
A fourth grade class with 24 students is playing tug of war with a rope against their teacher. Which of the following BEST describes the expected outcome?
The 24 students and the teacher will result in a tie since their forces are balanced.
The results cannot be unpredicted since balanced and unbalanced forces are random.
The teacher will win since the forces are balanced because the teacher will have more force pulling than all 24 students.
The 24 students will win since the forces are unbalanced because they will have more force pulling on their side compared to the one teacher.
. Students want to investigate how a marble can demonstrate a balanced force. Which situation below would BEST demonstrate a balanced force?
Student 1 sets up a ramp with a book and rolls a marble down the book.
Student 2 pushes a marble along a smooth surface, and the marble rolls along the surface.

Which would be the best way to label the directions for the investigation?
The black arrows should be labeled with the phrase “heat removed” and the white arrows should be labeled with the phrase “heat added.”
The black arrows should be labeled with the phrase “heat added” and the white arrows should be labeled with the phrase “heat removed.”
The black arrows should be labeled with the phrase “freezing” and the white arrows should be labeled with the phrase “melting.”
The black arrows should be labeled with the phrase “condensation” and the white arrows should be labeled with the phrase “evaporation.”
2. You are planning an investigation to show water change from a solid to a liquid. Which of the following experiments would show this?
Put a cup of water in the freezer.
Put a cup of water in the microwave.
Put a cup of ice in the sunlight.
Put a cup of ice in a cooler.
Examine the picture below:

Beaker #2 could be heated to 32 degrees, which will result in less energy.
Beaker #1 could be cooled to 32 degrees, which will result in less energy.
Beaker #3 could be cooled to 78 degrees, which will result in more energy.
Beaker #3 could be heated until 212 degrees, which will result in more energy.

. Jasmine filled two cups with equal amounts of water. She put a lid on Cup A and left Cup B without a lid. She then placed them outside on her deck on a warm spring day. She wanted to see what would happen to the water in each cup after several days.
The amount of water in Cup A will decrease. The amount of water in Cup B will increase. In the water cycle, water condenses to fill up lakes and rivers.
The amount of water in both Cup A and Cup B will remain the same. In the water cycle, water evaporates into the air but condenses to form rain and falls back to the earth.
The amount of water in Cup A will remain the same. The amount of water in Cup B will decrease. The water in Cup B may be completely gone. In the water cycle, water evaporates into the air.
The amount of water in Cup A will remain the same. The amount of water in Cup B will increase. The water in Cup B may be completely full. In the water cycle, water evaporates into the air.
2. A student wants to create a model of the water cycle to show what happens to a water droplet that just fell to the ground as snow. What should the student include next in the model and why?
Nothing will happen because the water droplet reached the end of the water cycle.
The water droplet will eventually evaporate because that’s the next step in the water cycle.
The water droplet will turn into rain because it is precipitation.
The water droplet will begin to condense and form a new cloud.
A student wants to draw the impact of the water cycle. Water is a clear, colorless, tasteless and odorless liquid that makes up seas, lakes, rivers and rain. It is one of the most common substances on Earth and in fact covers 70 percent of the planet's surface. Water from a pond in Georgia can end up watering a forest around the world in China.
What information should the student include to describe how a drop of water from Georgia can end up watering a forest in China?
The water cycle is a cycle that is constantly changing. The water will evaporate towards China.
This is impossible because water will evaporate, condensate in the clouds, and rain in the same area.
The water cycle is not limited to one area. The water will be pushed by winds when it becomes clouds.
The water cycle is a cycle that travels across the world in one day. Whenever water evaporates, it will quickly condensate and travel across the world.
Josh drew the picture below to show what he knew about the water cycle. He turned it into his teacher, but she gave it back to him because he did not label it. She told him he needed to label each number.
What label should be on each number and why?
1: Condensation forms clouds; 2: Evaporation from a body of water; 3: Precipitation such as rain, sleet, snow or hail; 4: Runoff is water that lands on the ground and moves down the hill to a body of water.
