The aim of this scenario is to study the effects of light pollution in the stars’ observation, energy consumption and waste, light spectrum.

For that, students will conduct an investigative work by goups with students from different grades.

Take away concepts

• Electromagnetic waves occur in a continous spectrum based on their wavelength.
• EM waves of a particular range of wavelengths are give names such as infrared and visible.
• Unlike mechanical waves such as sound or earthquake waves, EM waves can travel through empty space.
• EM waves are used for communication with satellites and for observing the Earth from space.
• Sunlight is made up of EM waves.

Based on computational physics research, Energy2D is an interactive, visual multiphysics simulation program that models all three mechanisms of heat transfer — conduction, convection, and radiation.

Students must be engaged in a highly motivating learning experience, which is closely related to the tasks and challenges of the real world.

Therefore, emphasis must be given on the learning-by-doing, where the activities in authentic context are strongly emphasized, which means the skills needed in working life, such as being able to work in teams, working in self-guided manner, and assessing of own actions (Thomas, 2000).
