This is science! It is the perfect hands on activity for Physics students working on Module 7: The Nature of Light and Module 8: From the Universe to the Atom.
In this program learners will:
- Work scientifically to conduct a physics investigation like a professional astronomer using simple low-resolution stellar spectroscopy. Using a 100 line per mm blazed gratings on our telescopes, learners will observe the first order spectrum of a target star
- Use specialised software and a calibrated instrument response curve to analyse and classify a previously collected spectrum
- Identify key absorption features such as the Hydrogen Beta line on A0 stars, peak wavelengths and then use that data to reveal the spectral class and other key characteristics including the evolutionary stage, surface temperature, colour and luminosity.
Every group will:
- Look through a telescope, weather permitting, at the surface of the Sun during the day or the Moon and planets at night. Using a blazed grating they will see the first order sprectrum of at least one star.
- Experience pristine dark sky in the digital planetarium where clouds never ruin the view
Please bring a USB drive with a minimum size of 16GB to allow you to take the data you collect back to your classroom.
