Usually making an observation leads us to asking questions. After we have asked a question, we might form an educated guess, based on our observation. That educated guess is called a ^...

Match the following descriptions with the correct scientific terms:

• The variable that is changed on purpose

• Dependent Variable

• An "If .... then prediction statement

• Independent Variable

• Represents the normal conditions

• Constants

• The variable that we measure

• Control

• Conditions that stay the same

• Hypothesis

Match the following parts of the experiment: Sophia became interested in insulation while her parent’s new house was being built. She decided to determine which insulation transferred the least amount of heat. She filled each of 5 jars half-full with water. She sealed each jar with a plastic lid. Then she wrapped 4 of the jars with a different kind of insulation, leaving one jar without insulation. She put the jars outside in the direct sunlight. Later, she measured the temperature of the water in each jar.

• Jar with no insulation.

• Independent Variable

• Temperature of water

• Experimental Group

• Type of insulation

• Dependent Variable

• How much water

• Constant

• Jars with insulation

• Control Group

Below are some of the parts of the scientific method. Read each phrase below and match it to the correct definition.

• Create a method to test the hypothesis

• State your Hypothesis

• Write a report to explain your findings.

• Perform the Experiment

• Follow your procedure.

• Draw Conclusions

• What did you learn from your data?

• Communicate Your Results

• Statement that describes an observation

• Plan an Experiment

Variables are any factors, traits, or conditions that can exist in differing amounts or types in an experiment. There are 3 main types of variables in an experiment. Please match the variable below with the correct definition.

• the one that is changed by the scientist

• Dependent Variable

• the one that the scientist focuses on

• Independent Variable

• quantities that a scientist wants to rem

• Controlled Variable

Read the question and then identify the variables below.

Is a classroom noisier when the teacher leaves the room?

• • Controlled Variables
    (What I keep the s

• Loudness, measured in decibels

• Independent Variable
  (What I change)

• • Same classroom

  • Same students

  • Same time of day

• Dependent Variables
  (What I observe)

• Teacher location: The teacher is either in the room or not in the room.

Read the question below and then match the types of variables with the correct example:

Do bicycle fenders keep the rider dry when riding through a puddle?

• Dependent Variables
  (What I observe)

• Fenders: Bicycle either has fenders or it doesn't

• Controlled Variables
  What stays the same

• The rider either gets wet or does not.

• Independent Variable - Observations

• • - Same type of bike and tires (except for the fenders!)

  • - Riding at the same speed

  • - Same size and depth of puddle
