A student constructs several terrariums to grow plants.

Each terrarium is exposed to a different amount of

sunlight each day. In order to determine the ideal

amount of sunlight. What is the independent variable?

Back

amount of sunlight

A student constructs several terrariums to grow plants.

Each terrarium is exposed to a different amount of

sunlight each day. In order to determine the ideal

amount of sunlight, what are the possible controlled variables?

Back

type of plant, same size terrarium

A student hypothesizes that green algae will grow fastest

when exposed to blue light. To test this hypothesis, the

student should design an experiment with what is the

independent variable?

Back

color of light

when exposed to blue light. To test this hypothesis, the

student should design an experiment with what is the

dependent variable?

Back

growth of green algae

Katie designed an experiment to determine which

type of soil absorbs the most water. To ensure that

experiment results have valid data, what are the controlled variables?

Back

amount of soil used, same container, same amount of water

Front

In an experiment about growth, some snapdragon seeds

were placed in dishes lined with moist paper towels at

differing temperatures. What is the

independent variable in this experiment?

Back

different temperatures

Marcella read an article on the internet that says plants grow better in acidic soil. She decides to test this statement by adding 15 milliliters of vinegar(acidic liquid) to the 0.5 L water container she uses to water her marigolds. She has two rows of marigolds.  She will water one row with the acidic water.  On the other row, she will water her marigolds with regular water from a 0.5 L container. She measures her marigold’s height each week for six weeks. What is the control group?

The row watered with regular water.
