Examine the Data
Seventh graders examine a teacher-created database and identify specific variables and develop hypothesis statements as to their possible effect. They create a summary statement either proving or disproving their hypothesis.
Curated OER
Interpreting Data-Working with Controls and Variables
Students review the meaning of control and variables, and state difference between dependent and independent variables. They complete a worksheet with the definitions and complete problems that show their understanding.
