Chapter 1 Scientific Processes & COL

Repetition in an investigation makes the data

• accurate

• replicated

• science-y

• in a graph

An observation

• is an explanation that may be right or wrong based on what you see

• uses the 5 senses to gain information and is always fact

• may be made during a hypothesis

• is written as an if/then statement

Which group in an experiment is not tested?

• control

• variable

• 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?

Mr. S normally uses praise as a reward to train his dog. He wants to know the best way to train his dog, so he sets up an experiment to find out if there is a better way to get his dog to respond to commands. What is his dependent variable?

• Type of reward
• Praise
• Type of dog
• Amount of time the dog follows commands

This part of the experiment serves as a basis of comparison:

• control group

• Independent variable

• dependent variable

• data

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, the independent variable is ...

• type of plant

• the amount of sunlight

• the type of music

• the type of liquid

The summary at the end of an experiment that explains the results.

• conclusion

• hypothesis

• procedure

• question

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 are the controlled variables?

• type of plant, amount of music, and sunlight

• plant growth

• water, apple juice, milk
