Students explore how various energy sources can be used to cause a turbine to rotate and then generate electricity with a magnet.
The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials
Be sure to go over safety precautions beforehand. Thermal gloves should be used whenever possible.
Educators will need to build the model first in order to understand where students might get stuck or injured.
Educators should point out that reversing the action of the apparatus in Part B demonstrates how electric motors work (also a feature of hybrid cars).
Be sure to remind the students to keep their bare skin away from the steam (page 7 of activity).
Hands-on activity that demonstrates how turbines work.
Good at demonstrating the relationship between magnetism and electricity.
Good selection of assessments to prompt student thinking and analysis.
Good hands-on activities to gain a tactile understanding of how a generator works.
Student answer sheets are missing, but the activity can be done without them.
Building (kinesthetic) type activities increase participation of students with different learning styles.
Necessary materials are commonly found in a classroom or at home.
