🧪 IB Chemistry Apprentice Lesson Plan
Topic: The Electromagnetic Spectrum
Level: IB Year 1 (Apprentice)
Duration: 60 minutes
Lesson Objectives
By the end of this lesson, students should be able to:
‣ Describe the electromagnetic spectrum and identify its different regions.
‣ Understand and apply the equation c = fλ.
‣ Differentiate between a continuous spectrum and a line spectrum.
‣ Explain the concept of quantized energy in atoms.
Lesson Outline
Introduction (0–5 minutes)
Start the lesson by asking students a few engaging questions:
What are some examples of invisible light or radiation around us?
Why do we wear sunscreen?
Allow brief responses, then explain that all of these examples are part of the electromagnetic spectrum, which we will study today.
Teaching Phase 1 – Overview of the Electromagnetic Spectrum (5–15 minutes)
Introduce the electromagnetic spectrum. Explain that it is a range of all electromagnetic waves, which vary by frequency and wavelength. Emphasize that all electromagnetic waves travel at the same speed in a vacuum – the speed of light, c = 3.00 × 108 m/s.
Key formula to introduce: c = fλ, where:
c = speed of light
f = frequency (Hz)
λ = wavelength (m)
Point out that high-frequency waves have short wavelengths and higher energy (like gamma rays), while low-frequency waves have long wavelengths and lower energy (like radio waves). Display a spectrum diagram showing the range from radio to gamma rays, with visible light in the center.
Teaching Phase 2 – Spectrum Types: Continuous vs. Line Spectrum (15–25 minutes)
Explain the difference between continuous and line spectra.
A continuous spectrum** contains all wavelengths in a range, like a rainbow produced when white light passes through a prism.
A line spectrum** shows only specific wavelengths or frequencies. This happens when excited electrons fall back to lower energy levels and release photons of specific energies.
Explain that energy is **quantized**—electrons cannot have just any amount of energy; only specific values are allowed. Use the helium line spectrum image as an example.
Real-World Examples and Class Discussion (35–45 minutes)
Give students three practical examples and discuss their uses:
1. Microwaves – Used in cooking and communications.
2. Ultraviolet (UV) rays – Cause sunburn; used in sterilizing equipment.
3. Gamma rays– Used in cancer treatment and in detecting radioactive materials.
Ask students:
Where do you see or use electromagnetic waves in your daily life?
Encourage short contributions to reinforce understanding.
Student Exercises (45–55 minutes)
Have students complete these three questions individually:
1. A wave has a frequency of 6.0 × 1014 Hz. Calculate its wavelength using c = 3.00 × 108 m/s.
2. Explain the difference between a continuous and line spectrum, with an example of each.
3. Why are gamma rays more dangerous to humans than radio waves?
Wrap-Up and Recap (55–60 minutes)
Call on a few students to briefly summarize one key thing they learned.
