Biology Semester 1 Exam Practice Questions

A series of steps designed to help you solve problems and answer questions is

• the scientific method

• results

• observations

• the two step

A possible explanation to a problem that has not yet been tested. 

• data
• theory
• hypothesis
• fact

What step does every scientific experiment begin with?

• hypothesis
• question/problem
• procedures
• conclusion

Testing a hypothesis often involves a(n):

• answer
• experiment
• problem
• safety check

The flower is red.

• Qualitative Data

• Quantitative Data

• Quantitative Data

When experimenting with the growth of a plant, a scientist uses three (of the same type of) plants, two different fertilizers, equal light, and equal water. What type of variable is the fertilizer?

• Dependent
• Independent
• Control
• Compound

What would the INDEPENDENT variable be in an experiment testing which types of paper airplane goes furthest?

• the paper used
• the type of paper airplane
• the distance of each plane's flight
• how hard the plane is thrown

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, what is the dependent variable?

• Type of plant
• Water, apple juice, milk
• Plant growth
• Color of the plant's leaves

How many variables do we want to test/change during a controlled experiment?

• 1

• 2

• 3

• 4
