the number of times the plants are watered

the number of leaves the plants grow

the amount of light the plants receive

Allie wonders if adding salt to water will affect how long it takes the water to freeze. She takes two ice trays and fills one with water and the other with water that has two tablespoons of salt added. She makes sure she puts exactly the same amount of water in each ice tray. She takes the trays and puts them side by side in the freezer and checks the ice trays every 10 minutes to see if the water in each tray has begun to freeze. What is the test (independent) variable?

The time it takes the water to freeze

It is January and Haley, Sarah and Becky are tired of having cold feet while waiting for the school bus to come in the morning. They decide to design an experiment to test the effectiveness of wool, cotton and nylon as insulators. They fill identical bottles with 200 ml of water at 100 C and place them inside each sock. They take the temperature of the water after 20 minutes. What is the outcome (dependent) variable?

Temperature of the water bottles

Type of material used as an insulator

A group of middle school students were given a course in speed-reading. The instructor was curious to see if the students were paid, would it influence their performance on a reading test taken at the end of the year. Half the students were offered $50 for obtaining a certain grade on the test, the other half were not offered money. What is the test (independent) variable?

The $$ - whether the students were paid

Francesca creates a model that shows the movements of the tectonic plates of Earth’s surface. If she wants to use the model to understand the concept of how a mountain is formed, how does the model help her?

It explains in detail how mountains are formed

It shows all of the plates in their correct layout

Which of the following statements describe the pressure from one layer to the next?

Pressure increases as the weight of the layers above increases.

Pressure increases with depth in the Earth, but it only applies to the mantle.

Pressure between layers remains constant regardless of depth or material composition.
