Differentiating the Blade Design Investigation

The blade design investigation can be customized to meet the needs of the students in your classroom. Choose a question for your students to investigate.

1. How many washers will our blade design be able to lift to the top of the weightlifter turbine?

OR

2. How much mass will our blade design be able to lift to the top of the weightlifter turbine?

Students should copy the question into their Student Guides. You may also type up the question and give each student a copy so they can glue the question into their Student Guides. Students should collect data during their investigation. Guide students in creating their own data table on page 13 of their Student Guides. You may also copy the table below and have students glue the table into their Student Guides. Suggestions for the column headings to go with Question 1 are: ƒTrial/Number of washers/Lifted to the top? (Yes or No) Suggestions for column headings to go with Question 2 are: ƒTrial/Mass/Lifted to the top? (Yes or No)
