The next solar eclipse is a once-in-a-lifetime science lesson: why only see it when your students can measure it?

In this activity, you'll turn a simple micro:bit in a pocket-sized observatory that records how daylight, temperature, and even patio noise levels decrease as the Moon slides in front of the Sun.

 

RECOMMENDED AGES: 12–18 years

LOMLOE COMPETENCIES:

• Learning to learn
• Digital competence
• STEAM Competition
• Social competence

OBJECTIVES:

• Create an observatory that measures environmental conditions during a solar eclipse like those in Spain in 2026, 2027 and 2028. In particular:
• Build and program a data logger with micro:bit.
• Measure in real time the flow of light, ambient noise, and temperature during an eclipse.
• Interpret sensor data to relate environmental changes to eclipse phases.

MATERIALS:

• Computer with internet access
• 1 micro:bit (v2 version recommended)
• Cable USB
• Battery Pack
• MakeCode for microbiteditor

INCLUSION:

• Programming steps with plain language and pictograms for students with cognitive disabilities.
• High-contrast MakeCode blocks and screen reader compatibility for visually impaired students.
