High School STEM

Week 4 April 27-May 1

Weekly Packet

STEM Objectives: Students will be able to: 

  • define electromagnetism.  
  • explain what circuits are and how they work. 
  • explore some basic electrical components. 
  • determine the voltage, resistance, amperage and watts around a circuit. 

Lessons and Student Instructions 
Lesson 1:  Watch some of the videos about electromagnetism and circuits, take notes (Cornell notes if you know them) and answer the questions. -OR- 
Read the first article and answer the questions.  
Make sure you know the vocabulary.  

Try the Simulations or Extension if desired. 

Questions 
How do resistors behave in series and parallel circuits? 
How have we harnessed electro-magnetism? How can we control it and make it do what we want? 
What is the relationship between magnetism and electric current? 
How have we applied this? 

Vocabulary

electro-magnetism - the creation of magnetic fields with the movement of electric charges and vice versa
resistor - causes resistance to current in a circuit
capacitor - collects and holds a charge until discharged
insulator - material that does not allow current to flow; plastic, rubber, glass
conductor - a material that allows for the free flow of current; most metals and carbon
LED - Light emitting diode; 
diode - material that only allows current to flow in one direction
inductor- component that intentionally turns electricity into magnetism
induction - creating a movement of electrons by a movement of magnetism and vice versa

electromagnet - coil of wire around core that focuses the magnetic field lines created by the electric current
right hand rule - the direction of the magnetic field around a current in a wire.
Power Law - Watts = Volts x Amps
magnetism - lines of force created by electric current and the alignment of ferrous particles
motor - transforms current into circular motion through induction of magnetism
solenoid - an electromagnet that pushes a plunger in and out
thermocouple - two different thin metal pieces that have different rates of expansion and change resistance at different temperatures
fuse - a safety device that melts if there is too much current, such as a short circuit
transformer - using different number of turns of input and output coils around a shared core different voltages can be obtained through induction.
