PURPOSE

To make a mini model of a steam turbine

To see how heat can change liquid into steam and generate

power

MATERIALS

100 PLUS aluminum can

Screw

Bamboo stick

Aluminum foil

Egg tart tin

Water

Gas stove

PROCEDURE

1. I shared the can of soda with my sister

2. Rinsed the can

3. My dad hammered two holes with a screw

4. Filled half the can with water

5. Made the stand out of a 20cm foil

6. Cut some lines onto the egg tart foil

7. Attach the bamboo stick to the middle of the ebb tart foil

8. Attach the bamboo stick to the foil stand

9. Put the can on top of the gas stove

10. Watch the wheel spin

OBSERVATIONS

It was hard to get the wheel to start

spinning

When the water boiled, the can shook

and wobled

Because the the hole was not under

the fan

CONCLUSIONS

It takes a lot of energy to generate steam.

The steam should be underneath the fan

THE BIG IDEA

steam turbines make most of the world’s electricity

steam turbines are very energy efficient

geothermal (from the earth’s hot core) energy will be a good clean

source of energy for steam turbines in the future
