Water, water. – minibeasts
But, is it clean?
What, a gas?
Keep cool!
It droppeth from. . . ? – evaporation & rain gauge
Time measurement
Me and my shadow
That sinking feeling
Water Clocks and Clepsydra
Time is but a passing shadow
DIY sundial
Carpe Diem
Fair, drawin’ in?
Roamin’ and the gnomon
To every season: turn, turn
Teacher centred system
Planetary sizes
Even farther out – night sky
Wind, windpower and windmills
Harnessing the wind
Windmills of the mind
Blow the wind Southerly
Seize the moment
Power from the wind
