Variable Practice
Identify the Independent Variable:
The higher the temperature of the air in the oven, the faster a cake will bake.
What is the temperature.
What is the third step of the scientific method?
What is Question?
What is the secret ninth step to the scientific method?
Identify the Dependent Variable:
Lemon trees receiving the most water produced the most lemons.
What is the amount/number of lemons?
"If... Then... Because..."
What step is this an example of?
What is:
Step 4 or Hypothesis?
What is step number 7 of the scientific method?
What is analyze?
Identify what the control group and the experimental group would be:
An investigation found that more bushels of potatoes were produced when the soil was fertilized more.
What is
Control: Bushels that are not fertilized.
Experimental: Bushels that are fertilized.
What step is being explained?
"Design a doable experiment to test the hypothesis. Using the past research to determine what temperature and what carrot seeds to use, the scientist designs an experiment to grow seeds in the same type of soil with varying amounts of nitrate added."
What is:
Step 5 or Design and Plan?
Which step is being explained:
"Confirm, support or reject the hypothesis. Wonder about new ideas or experiments to further test the scientific question."
What is:
Conclude or Step 8?
Identify the constant, the independent and dependent variable:
Students of different ages were given the same puzzle to assemble. The puzzle assembly time was measured
What is:
Constant: Puzzle
Independent: Age
Dependent: Time
Define/Explain step 3 of the scientific method.
What is Question:
Form a scientific question, a question that is testable with an experiment.
What step is explained:
"An educated guess to answer the scientific question."
What is:
Step four or Hypothesis?
Identify both the independent and dependent variables as well as the constants:
An experiment was performed to determine how the amount of coffee grounds could affect the taste of coffee. The same kind of coffee, the same percolator, the same amount and type of water, the same perking time, and the same electrical sources were used.
What is:
Constants: Coffee type, percolator, type of water, perking time, and electrical source.
Independent: Amount of coffee grounds
Dependent: Taste of Coffee
