Reading the Kp index
Ages 11–1445 minObjective. Students read a real NOAA dataset, classify each day as quiet or stormy, and explain why the Kp scale is logarithmic-ish (each step is a bigger jump than the last).
Materials
- Projector or shared screen
- Printed worksheet (use the table below)
- Coloured pencils — green, yellow, orange, red
Standards touched
- MS-ESS1-1
- NGSS Patterns crosscutting concept
Lesson flow
- Open /space-weather and walk through the Geomagnetic Storms card together.
- Open /this-week and find the Kp values for the last 7 days.
- Have students fill in the table and colour-code each day (green ≤ 3, yellow 4, orange 5–6, red 7+).
- Discussion: did anyone notice the news that day? What might astronauts have done differently?
