FULL OF ENERGY!

FULL OF ENERGY!

FULL OF ENERGY SCIENCE! Here are some of the demonstrations we saw in workshops.

Stored energy in hand warmers Our hand warmers were full of a cold liquid when they were handed out. When the metal catalyser inside the liquid was clicked they quickly changed. Two things changed: 1) They became warm 2) The liquid altered to a salt-like solid When the hand warmers have cooled you can store more energy by boiling the hand warmer bags in water. Soon the solid changes to liquid again and they are ready for the next time they are needed. Can you think of any other forms of energy stored in chemical form?

Stored energy in a toy tractor Our toy tractor has a button to press down. When you push the button movement energy is stored in a spring. Stop pressing the button and the tractor moves! The spring releases the stored energy and moves the wheels of the tractor. Do you have any friction or clockwork toys which store energy in a spring as well?

Windmills & water wheels Blow on to a windmill and it starts to turn. Our toy water wheels start to spin as water is poured into them. One machine uses the energy in moving air and the other water to turn a wheel. Both hydroelectric and wind turbines use a Tesla generator to change this motion into electricity. This is an example of renewable energy production.

Solar Robot Our solar robot has a solar panel on its head. When the light shines on the special surface of the panel it is changed from light and heat energy into electrical energy. The electricity then powers a Tesla motor to make the robot’s wheels move along. What changes in energy have happened?

Steamboat We lit a candle under the boiler of a toy steamboat. When the water in the boiler was hot a burst of steam came out of the exhaust pipe and at the same time cold water was sucked into the inlet pipe. This new water is heated immediately making a new burst of steam. The bursts of steam propel the boat forwards making a ‘phut phut’ sound. What materials changed? What sorts of energy changed in this demonstration? this dem

Insulation We made two pots of tea with hot water from the same kettle. On one we put a tea cosy, but not on the other. Half an hour later we felt the two pots. Can you guess what happened?

Greenhouse gases high in the atmosphere act like a giant tea cosy above the North Pole. The sun’s warmth is insulated by the gases and so the ice cap has started to melt dramatically.

TEACHING THE SONGS AND USE OF BACKING TRACKS

We hope you enjoy singing the seven songs.

Those who can play guitar or piano using the chords provided in the sheet music are

encouraged to accompany these songs with live music.

But there is also a CD available to accompany this book as well as links to MP3 versions

and PDFs of lyrics from www.nea.org.uk.

Tracks 1- 7 are with lead vocals. Tracks 8 –14 are instrumental accompaniment only.

The songs are best taught by call and echo or call and response, in small bite sized

pieces.

PDFs projected onto white boards with children’s heads up are preferable to paper

sheets with faces buried and voices muted.

THE MUSICIANS

The musicians featured on the backing tracks are Richard Scott (vocals and guitar),

Ken Patterson (bass and keyboards), Gerry Hunt (guitar, bass, clarinet, sax and fiddle)
