High School STEM

Week 3 April 20-24

Weekly Packet

STEM Objectives: Students will be able to:

  • explain the basic principles of electricity
  • explain what batteries are and how they work
  • list battery uses in your daily life
  • describe the different applications of batteries and current research

Lessons and Student Instructions

Lesson 1: Watch the videos about Electricity and Batteries, take notes (Cornell notes if you know them) and answer the questions.


Read the articles and answer the questions.

Make sure you know the vocabulary.


What is electricity?

What are the parts of a battery and what do they do?

Precisely how are batteries tuned for different applications?

What are areas of battery research?


Electricity - movement of charged particles in a conductor

Electron – negatively charged particle

Battery - chemically creates electricity

Battery cell - a single unit of electrodes and electrolyte – NOT hooked together

Electrode - material that can create a voltage potential in a battery

Electrolyte - material that allows for the passage of charged particles in a battery

Positive - attracts electrons; also marked by RED

Watts - measurement of power; in electricity it is Watts = Amps x Volts

Parallel - multiple paths for the electricity to flow in a circuit
Negative - gives up electrons; also the color BLACK and called ‘ground’ or GND

Circuit – connecting a load (lights, motors, heaters) to the positive and negative of a power source

Short circuit - directly connecting the positive and negative of an electricity source

Voltage - the pressure that makes electrons move. Measured in Volts (V)

Resistance - resistance to current flow: Measured in Ohms (Ω)

Current - movement of electrons: Measured in amperes (I)

Ohms Law - the relationship between Volts, Amps and Ohms: Volts = Amps x Ohms

Series - single path for the electricity to flow in a circuit
