### A tornado in a tube relates to science because of the vortex it creates.

• A.

True

• B.

False

A. True
Explanation
A tornado in a tube relates to science because it creates a vortex. In science, a vortex refers to a swirling motion of fluid or air, often forming a tornado-like shape. The tornado in a tube is a demonstration or experiment that replicates the conditions and characteristics of a real tornado, allowing scientists and students to study and understand the principles behind tornado formation and behavior. Therefore, the statement is true as the vortex created by the tornado in a tube is indeed related to science.

### In a vortex, water goes up and air goes down.

• A.

True

• B.

False

B. False
Explanation
In a vortex, such as a whirlpool or tornado, water or any other fluid rotates in a swirling motion. The centripetal force causes the fluid to move towards the center of the vortex, creating a downward flow. Conversely, the air or any other gas in the vortex moves in an upward direction due to the centrifugal force. Thus, the statement that water goes up and air goes down in a vortex is false.

### A terrarium contains various aquatic species.

• A.

True

• B.

False

B. False
Explanation
The statement says that a terrarium contains various aquatic species, but this is not true. A terrarium is a sealed container that is used to create a controlled environment for plants or small animals. It typically contains terrestrial species, such as plants, insects, or small reptiles, rather than aquatic species. Therefore, the correct answer is false.

### Condensation is the first stage in the water cycle.

• A.

True

• B.

False

B. False
Explanation
The statement that condensation is the first stage in the water cycle is false. The correct answer is false because the first stage in the water cycle is actually evaporation. Evaporation occurs when water from bodies of water, such as lakes or oceans, is heated by the sun and turns into water vapor, rising into the atmosphere. Condensation occurs after evaporation, when the water vapor cools and turns back into liquid water, forming clouds.

### The science behind the terrarium activity involves learning more about ecosystems.

• A.

True

• B.

False

A. True
Explanation
The terrarium activity involves creating a small, enclosed ecosystem that replicates the natural environment. By observing and taking care of the plants and animals within the terrarium, individuals can learn about the interdependence of living organisms and the balance required for a healthy ecosystem. Therefore, the statement that the science behind the terrarium activity involves learning more about ecosystems is true.

### The 2-liter terrarium experiment must be kept in a cool, dark place.

• A.

True

• B.

False

B. False
Explanation
The 2-liter terrarium experiment must not be kept in a cool, dark place.

### At the science fair, the students' 2-liter bottle experiments will be displayed in the cafeteria.

• A.

True

• B.

False

B. False
Explanation
The statement is false because it states that the students' 2-liter bottle experiments will be displayed in the cafeteria at the science fair. However, it does not specify whether the experiments will actually be displayed in the cafeteria or not. Therefore, we cannot assume that the statement is true.

Rate this question:

• 9.

### Which of the following demonstrates the correct order of the water cycle?

• A.

Oceans, Lakes, Rivers, Streams

• B.

Evaporation, Condensation, Precipitation

• C.

Condensation, Evaporation, Precipitation

• D.

Rain, Snow, Sleet, Hail

B. Evaporation, Condensation, Precipitation
Explanation
Evaporation is the process in which water changes from a liquid to a gas, typically from the surface of bodies of water. Condensation is the process in which water vapor in the air cools and changes back into liquid water, forming clouds. Precipitation is the process by which water falls from the atmosphere to the Earth's surface in the form of rain, snow, sleet, or hail. This order accurately represents the sequence of events in the water cycle, starting with evaporation, followed by condensation, and ending with precipitation.

### Students are required to do one of the three experiments listed in the brochure.

• A.

True

• B.

False

B. False
Explanation
The statement is false because the students are not required to do any of the three experiments listed in the brochure.
