Wedi’i anelu at ddisgyblion 14-18 oed, mae’r gweithgaredd hwn yn cyflwyno’r disgyblion i’r Cynllun Dosbarthu Hubble ar gyfer galaethau ac mae’n rhoi her i’r disgyblion i drio dosbarthu amrywiaeth o alaethau go iawn. Gall fod yn ddefnyddiol hefyd fel ffordd o drafod y gwahanol fathau o alaethau yn y Bydysawd.
Aimed at pupils aged 14-18, this activity will focus on investigating Kepler's three laws of planetary motion, with a particular emphasis on Kepler's Third Law: The Law of Periods, which explains the relationship between the distance from an orbiting body to a system's centre of mass and its period of orbit.
Pupils 16-18 / more able students: The relationship will also be put to the test by calculating the mass of the host star of the stellar system TRAPPIST-1 using the known orbital periods of its exoplanets.
Aimed at pupils aged 14-18, this workshop introduces pupils to the Hubble classification scheme and challenges students to attempt to classify a range of galaxies. It can be used as an opportunity to discuss the different type of galaxies found in the Universe, or as a follow up to such a discussion.
