Eclipse 2028 practical guide
Eclipse 2028 Classroom Pack: Lessons and Activities
The eclipse connects geometry, geography, time, evidence and observation without requiring students to look directly at the Sun.
In brief
Teach scale and shadow first, map the umbra second, practise indirect projection third, then have students create a coordinate-specific plan with sources and uncertainty.
Lesson one: model the shadow
Use a lamp, small ball and screen to distinguish umbra and penumbra. Ask how distance changes shadow size, then identify why the model is not to scale. The goal is the relationship between alignment and shadow, not a perfect miniature solar system.
Lesson two: read the path as data
Plot selected NASA centre-line and limit coordinates. Convert UTC samples to relevant local civil time and discuss why timezone labels need dates. Compare a city centre with another coordinate and explain why a path band is not a list of approved sites.
Lesson three: project safely
Construct a pinhole projector or use a perforated card to cast multiple solar images onto a shaded surface. Look at the projection, never through the hole. Teachers should review current official guidance and prohibit unsupervised optical improvisation.
Lesson four: evaluate claims
Give students a forecast icon, monthly climate average, eclipse map and sourced contact table. Ask what each can support. This separates weather from climate, geometry from land access, and calculated time from observation.
Assessment task
Students create a one-page plan for a stated coordinate: event type, contact sequence, safe observation method, one uncertainty and two sources. They must label assumptions. The task can be completed without travel and should never require direct solar viewing.
Extension work can compare two coordinates, audit an online claim, or design a data table for temperature or light. Mark transparent method and evidence more highly than confident prediction.
Teacher preparation and risk control
Before class, test every demonstration in the room where it will run. A projection activity needs a stable screen, a controlled viewing direction, and an adult who can stop the activity immediately. Do not improvise with binoculars, telescopes, cameras, mirrors, or homemade filters. Students can learn the geometry from projected images, diagrams, and supplied data without any direct look at the Sun.
Prepare two datasets: one with clean NASA path samples and one with deliberately incomplete or misleading claims. Ask students to label what is measured, calculated, inferred, or unknown. A strong answer might say that a city is inside the broad path but that a particular sports field still needs access permission and a horizon check. That distinction is the central research skill.
Assessment rubric
- Geometry: the student distinguishes umbra, penumbra, magnitude, and totality.
- Safety: the plan uses indirect projection or verified viewers and identifies who controls the procedure.
- Evidence: every important number has a source and a date.
- Uncertainty: assumptions and limitations are stated rather than hidden.
- Communication: another person could follow the plan without guessing.
Extend the lesson
Pair this pack with the how eclipses work explainer for older students, verify current path data on the interactive map, review eye safety before any classroom demonstration, and see citizen science during the eclipse for an extension project.
