Scientists often use visual or mathematical representations to investigate items that are very large, very small, or otherwise difficult to study.  What are these visual or mathematical representations called?

• experiments
• hypotheses
• models
• observations

Multiple Choice

 A testable idea or explanation that leads to scientific investigation based on prior knowledge is known as: 

• theory
• experiment 
• observation
• hypothesis

Multiple Choice

 An organized procedure to study something under controlled conditions is called:

• theory
• experiment 
• observation
• hypothesis

Kaylee reads an article that states that the frequency of chirping by crickets is related to the temperature of

their environment. She wants to conduct an experiment to see if this is true. Kaylee states this hypothesis:

Crickets chirp more frequently when the temperature of their environment increases. What is the test

variable (independent variable) and outcome variable (dependent variable) in Kaylee’s experiment?

• a.test variable (independent variable): number of crickets; outcome variable (dependent variable): frequency of chirping

• b. test variable (independent variable): temperature of environment; outcome variable (dependent variable): frequency of chirping

• c. test variable (independent variable): number of crickets; outcome variable (dependent variable): temperature of environment

• d. test variable (independent variable): frequency of chirping; outcome variable (dependent variable): temperature of environment

Multiple Choice

What is the outcome (DEPENDENT) variable?

• plant height

• time in days

• sunflower

• daisy

Multiple Choice

Which of the following hypotheses could be tested by this experiment?

• Honeybees prefer to visit rose plants
• Honeybees prefer to visit red flowers.
• Honeybees prefer to visit flowers in the morning
• Honeybees prefer to visit Portland rose flowers between 9 and 10
