Unit Planning Organizer

Subject:  Integrated Science                                      

 Grade:   10

Unit  1:   Experimental Design (9.0)                                     

 Pacing :  4 weeks

Essential Question(s):

  1. What would happen to your experiment if you had more than one independent variable?
  2. What are some errors in experimental design that will produce invalid results?
  3. Why should you include your data in your conclusion statement?

 

Big Idea(s):

1. Having more than one independent variable in your experiment doesn’t allow you to know what caused the dependent variable to change.

2. All experiments we will conduct should have a control group, controlled variables, and more than one trial to be considered a valid experiment.

3. Conclusion statements must be supported with data produced in the experiment, in order to provide evidence of your results.
