Action – Part B: Radiometer

How does it work

Light has a double nature: it behaves as a wave for many phenomena, but it’s also composed of particles (photons)

When a photon collides with a surface, it presses on it, and the amount of this pressure depends on the reflectivity of the surface.

A completely reflective surface (aluminium foil) is pressed more than a completely absorbitive surface (black paper).

Each fan blade has 2 opposed surfaces: one covered by aluminium, the other by black paper.

When the light strikes the fan, it rotates because of the difference of pressure on its blades.

action

operation

Create something that they can see in the

town/village near them, e.g. car/house etc using

recycled materialsthat they have gathered

as a class.(Individual)Create a sun-pressure turbine using a bottle, aluminium and paper

which can all be recycled. (Collaborative groupwork)This will all be displayed as a model sustainable

town.

Look at home and in school for items that can be

recycledDesign and make urban item

(cut,paste, paint, etc)Build the fan (alternate

aluminium and paper ‘wings’ of the fan)

Put in the bottle (vacuum) Place in the model town in

sunny spots.

goalsPromote the mindset that things can be

used again and again for

many different

purposes as part of the

broader goal of cultivating

Environmental Awareness;Recognise that solar

energy can be exploited by people as an alternative

and possibly more viable

form of energy .
