QUIZ 25: True or False… The Dust Bowl is a volcano in the USA?
False. The Dust Bowl in America is not a volcano. The Dust Bowl was caused by the introduction of new farming techniques, over farming to produce food for the war and a serious drought in the 1930’s. The top soil was removed and heavily deposited across the land, during major dust storms. Many people lost their farms, animals, machinery and lives.

It was a tough question this week, with only a few people getting it correct. Congratulations to Zanthea Zwager of 7/3 for winning the quiz, an outstanding effort!

If you have ever sat back and thought about how a motorbike runs, you would know that it takes a bit of science to work (e.g. Physics – combustion).

A Honda CTX200 Bushlander Motorbike has a 197cc motor. What does this mean?

A 197cc motor means the motorbike has the capacity to hold 197 cubic centimetres of a fuel/air mixture in its cylinders at full expansion. The cylinders are where combustion occurs. The process of combustion in a motorbike is important as this gets the motorbike going ready for you to ride.

Generally speaking, the greater the cc of a motorbike the greater the power and carrying capacity it has.

Congratulations to Zachary Sullivan of 7/2 for winning this week’s Science Quiz!

Once again, 7/4 had the highest number of student entries. I am very proud of you 7/4, keep up the great work! It is a fantastic achievement. I have had one person answer every Science Quiz correctly to date.

Great work Ms Timms!
