  Weather and Climate

Demonstrate that air does have weight [1 kilogram per square centimetre]  by inverting a glass of water which is covered by a plastid lid Create your own rain with frozen container of ice sitting over a kettle - water vapour condenses on the cold metal surface.
Candle under water experiment Demonstrate that water is the only substance that gets lighter and less dense as it freezes and show how important that becomes to sea life in winter.
Sheet of newspaper and a piece of wood Show how metal expands when hot and shrinks when cold by using the blow torch and the ring and ball.
Show a visible change in temperature for a thermometer by using a hair dryer on it. Show how much of the iceberg that struck the Titanic was below the water line by dropping an ice chunk in water and observing how much is under the water surface
Demonstrate the law of inertia with this experiment called Plunk [card and clothes pin which drops into the water] Demonstrate Bernoulli's principle of aerodynamics that moving air exerts less pressure than slower moving air by placing a ping pong ball over a stream of moving air created by a hairdryer.  Take the ping pong "ball for a walk!"
Sprinkle a drop of methyl hydrate on your hand to demonstrate that evaporation removes energy.  Methyl hydrate is great because it evaporates so quickly. Use the class hygrometer to calculate the @Relative Humidity of the classroom.
Demonstrate weight of air by using the 2 mini plungers - remembers the air weighs 1 kg per square centimetre Demonstrate the principle of evaporation and surface are by putting 2 paper towels on a counter to dry - one is scrunched up and the other is laid flat - which will dry the fastest?
Demonstrate the water cycle by observing how a container of dirty water evaporates and leaves the residues behind, therefore the precipitates stay behind and only pure water evaporates and condenses and returns as rain. Show how a prism creates a spectrum.  Do a number of demonstrations which show us what vision really is, from a model of the eye to watching the pupil shrink and grow with light switches turning off and on to students' visual response to red, blue and green lighting for short periods of time causing the cones of either red or green to go to sleep and over react.
