Use a Christmas ball orbiting a lamp to make a secondary transit visible, or compare the reflected light of different surfaces with phyphox — and discuss what reflectivity means for exoplanets.

Flash one sketch onto an original Arduino Nano 33 BLE Sense and read its sensors live in phyphox on your smartphone — seven ready-to-import sensor experiments for the classroom.

An interactive educational game in which students identify the chemical elements in an exoplanet's atmosphere by analysing absorption spectra — available for Android, Windows, and macOS.

Compare how a CO₂-rich atmosphere and clean air warm up under an infrared lamp using an effervescent tablet and a temperature sensor inside a sealed container.

Mount an infrared sensor on a BLE mouse, drive it away from an infrared lamp, and watch phyphox plot the IR temperature signal against distance — a qualitative analogue for stellar heating.

A narrative educational game in which students discover stellar parallax, build a geometric model of distance measurement, and determine the distance to an unknown star — with three difficulty levels.

Build a spacecraft prototype from everyday materials, seal a pressure sensor inside, and test it under a vacuum bell jar — measuring whether your crew would survive.

Compress a gas-filled syringe with an external pressure and temperature sensor inside — and watch phyphox record the simultaneous rise in both quantities, an analogy for collapsing stellar nebulae.

Stick a small paper circle on the lamp to simulate a starspot, then orbit a Styrofoam ball past the sensor — and see how the spot deforms the exoplanet light curve.

Move a smartphone around a lamp to create a permanent day and night side and compare the light on each side — or measure temperature and light on both sides with two SensorTags in phyphox.

Simulate exoplanet detection by moving a Styrofoam ball around a lamp and recording a real-time light curve with phyphox.
