8.6 use the relationship between orbital speed, orbital radius and time period: orbital speed = (2 × × orbital π radius)/time period v = (2 × × r)/T π Executive function Critical thinking 57 Section 8: Students will be assessed on their Activity: Adaptability Problem solving Astrophysics ability to: video about the life cycle of Analysis c) Stellar evolution stars. Reasoning 8.7 understand how stars can be Interpretation classified according to their colour Class practicals: Decision making Observe how colour of 8.8 know that a star’s colour is Videos filament lamp changes with related to its surface temperature change in voltage supplied. Take measurements of describe the evolution of of 8.9 voltage and current so that similar mass to the Sun through the power can be calculated for following stages: each colour. Nebula Star (main sequence) Research artwork of Red star and supernova of 1054, White dwarf along with accounts of SN1987A. 8.10 describe the evolution of stars Use light-meters to measure with a mass larger than the Sun intensity of LEDs/torches as a function of distance. Demonstration: 8.11P understand how the brightness of a star at a standard
