During his class visit Elliot Tait explained the Albedo Effect to the class.  This is the ability of surfaces to reflect sunlight.  We found out that clean fresh snow reflects around 80-95% of the light that hits Earth.  This can make dark days feel a lot brighter when there is snow fall.  It also explains why our poles are so important in combatting climate change.

In class, we experimented with different light sensors coded into our microbits.  We learned how to use if/else statements and to code a display or alarm for a certain light level.  Some learners then moved on to a more advanced project, using radio signals to allow two microbits to communicate information.

 

As it snowed, we took our learning outdoors to test our light sensors in different conditions.  We certainly picked up high levels of light from the fresh snowfall.
