Common Core ELA Standards:
CCSS.ELA-LITERACY.RST.11-12.2: Determine the central ideas or conclusions of a text; summarize complex concepts, processes, or information presented in a text by paraphrasing them in simpler but still accurate terms.
CCSS.ELA-LITERACY.RST.11-12.3: Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.
Main challenge: Add 4 LEDs to the chairs of the main Rotating part and use potentiometer to control the speed of motor.
Time: 60 mins Procedure: • Students will connect 4 LEDs on series and on parallel to see the difference between them. • Students will compare between the different connections. • Students will use the potentiometer to control the speed of motor.
