Topic: Ohm's Law

Learning Outcomes: By the end of this module, students will be able to:

  1. Remember: State Ohm's Law and identify the symbols and units for voltage, current, and resistance. i.e. V, I and R
  2. Understand: Explain the relationship between voltage, current, and resistance in a simple circuit.
  3. Apply: Solve basic circuit problems involving Ohm's Law involving real life scenarios to cater for the new curriculum.
  4. Analyze: Analyze the behavior of current and voltage in series and parallel circuits using Ohm's Law.
  5. Evaluate: Assess the impact of changing resistance on current flow in different circuit configurations.
  6. Create: Design a simple circuit with a specific current and voltage using Ohm's Law and simulate its behavior.

Learning Activities and Digital Tool Integration:

Level 1: Remembering

  1. Activity: Students will watch a short introductory video explaining Ohm's Law and defining voltage, current, and resistance with their respective units.
  2. Digital Tool: YouTube, google and AI (e.g., search for "Ohm's Law explained simply").
  3. Assessment: Students will complete a short online matching quiz identifying the terms (voltage, current, resistance) with their symbols (V, I, R) and units (Volts, Amperes, Ohms).
  4. Digital Tool: Quizizz

Level 2: Understanding

  1. Activity: Students will interact with an online simulation where they can manipulate voltage, resistance, and observe the resulting current in a simple circuit. They will describe the relationship they observe.
  2. Digital Tool: PhET Interactive Simulations (University of Colorado Boulder) - specifically the "Circuit Construction Kit: DC" simulation.
  3. Assessment: Students will write a short paragraph explaining in their own words the relationship between voltage, current, and resistance based on their observations in the simulation. They will submit this through the LMS.
  4. Digital Tool: Google Classroom or Moodle (for submission).

Level 3: Applying

  1. Activity: Students will work through a series of practice problems involving Ohm's Law. These problems will require them to calculate voltage, current, or resistance given the other two values.
  2. Digital Tool: Worksheet Generator websites (e.g., Math-Aids.com has physics sections) to create varied problem sets. Students can solve these on paper or using a digital document.
  3. Assessment: Students will submit their solutions to the practice problems online. The teacher can provide feedback digitally.
  4. Digital Tool: Google Docs or Microsoft Word (for students to show work), Google Classroom or Moodle (for submission and feedback).

Level 4: Analyzing

  1. Activity: Students will use a circuit simulation tool to build and analyze series and parallel circuits. They will predict how changes in resistance in one part of the circuit will affect the current and voltage in other parts, and then verify their predictions using the simulation's measurement tools.
  2. Digital Tool: CircuitVerse (an online circuit simulator) or the PhET Circuit Construction Kit: DC (allowing for more complex circuits).
  3. Assessment: Students will create a short report (with screenshots from the simulation) explaining their analysis of how resistance changes affect current and voltage in both series and parallel circuits.
  4. Digital Tool: Google Slides or Microsoft PowerPoint (for creating the report), Google Classroom or Moodle (for submission).

Level 5: Evaluating

  1. Activity: Students will be presented with different real-world scenarios involving electrical circuits (e.g., dimming lights, overloading a circuit). They will need to evaluate the situation using their understanding of Ohm's Law and explain the potential consequences of changing resistance in these scenarios.
  2. Digital Tool: Online research tools (e.g., Google Search) to investigate real-world applications and potential issues related to Ohm's Law.
  3. Assessment: Students will participate in an online discussion forum where they share their evaluations of the given scenarios and respond to their classmates' perspectives.
  4. Digital Tool: Google Classroom Discussion Forum or Moodle Forum.

Level 6: Creating

  1. Activity: Students will be given a target current and voltage and will need to design a simple circuit (using a battery and one or more resistors in series) that achieves these values based on Ohm's Law. They will then build this circuit virtually using a simulation tool and verify their calculations.
  2. Digital Tool: PhET Circuit Construction Kit: DC.
  3. Assessment: Students will submit a design plan (including their calculations and a schematic of their circuit) along with a screenshot of their working simulated circuit demonstrating the target current and voltage.
  4. Digital Tool: Google Docs (for the design plan),PhET (for the simulation), Google Classroom or Moodle (for submission).
