Aftermath of the Rising: Executions & Public Opinion
Investigate the British response to the Rising, the executions of its leaders, and the shift in Irish public sentiment.
Key Questions
- Analyze how the British government's response to the Rising influenced Irish public opinion.
- Evaluate the impact of the executions on the nationalist movement.
- Explain how propaganda was used by both sides in the aftermath of the Rising.

About This Topic
The Electromagnetic Spectrum (EM Spectrum) expands the study of waves to include all forms of electromagnetic radiation, from low-frequency radio waves to high-energy gamma rays. Students learn that all EM waves travel at the speed of light in a vacuum but differ in their frequency and wavelength, which determines their energy and practical applications. This topic bridges the gap between classical wave theory and modern quantum physics by introducing the concept of the photon.
In the NCCA framework, this topic is linked to both health (UV and X-ray safety) and communication technology. Students must understand how different bands of the spectrum are detected and used in everyday Irish life, such as microwave ovens, TV remotes, and medical imaging. This topic comes alive when students can physically model the patterns of the spectrum and participate in collaborative research into the risks and benefits of various radiation types.
Active Learning Ideas
Inquiry Circle: Infrared Detection
Students use digital cameras (which can often 'see' IR) to observe the signal from a television remote. They then test various materials to see which are transparent or opaque to IR radiation, presenting their findings on how this affects remote control use.
Gallery Walk: Applications of the EM Spectrum
Groups are assigned one band of the spectrum (e.g., X-rays, Microwaves). They create a 'safety and utility' poster detailing how it's produced, detected, and its role in modern society. Students circulate to fill in a summary table for all seven bands.
Formal Debate: The 5G and Health Controversy
Students research the difference between ionizing and non-ionizing radiation. They then hold a debate on the safety of 5G technology, using their knowledge of the EM spectrum and photon energy (E = hf) to support their arguments with scientific evidence.
Watch Out for These Misconceptions
Common MisconceptionRadio waves are a type of sound wave.
What to Teach Instead
Radio waves are electromagnetic radiation and can travel through a vacuum, whereas sound is a mechanical wave requiring a medium. A peer-discussion comparing how a radio works versus a speaker helps students distinguish between the signal (EM) and the output (Sound).
Common MisconceptionAll radiation is ionizing and dangerous.
What to Teach Instead
Only high-frequency waves (UV, X-ray, Gamma) have enough energy to ionize atoms. Using a spectrum chart to show the 'ionizing cutoff' helps students understand why visible light and radio waves do not cause the same biological damage.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
