A tornado is a natural disaster. It is a violent column of air that swirls around buildings and houses. They appear in a funnel shape or in a slender-rope like form. A tornado can destroy large buildings, trees and vehicles.
Most tornadoes form from thunderstorms. A tornado occurs when warm, moist air and cool, dry air meets creating instability in the atmosphere. A change in wind direction and an expandation in wind speed creates an invisible, horizontal spinning effect in the lower atmosphere.
A waterspout is caused by tornadoes. It is just like a tornado except that it twirls only around the top of the sea.
After a tornado hits, many houses are broken down or covered in rubble. This causes a lot of thunderstorms and very heavy rain.
A tornado is very dangerous and can cause a lot of damage. There are a lot of tornadoes that forms in North America because they get a large source of moisture from the Gulf of Mexico and they get warm dry air from other countries which forms the huge tornadoes.
Learning Intention: We are learning to follow the structure of an explanation.
Success Criteria: I know I can do this when I write an introduction, followed by the explanation, the effects and a concluding sentence to explain how a tornado forms.
When the prayer was over, I went straight to the table with a plate ready to be served with delicious homemade food. I grabbed some chopsuey, taro, pork and some chinese food like noodles and sweet and sour chicken. The food was delightful and my favourite part was eating the pork because it was exquisitely hot and tender. 
When we arrived at Pak'n'Save, we grabbed a trundler with a yellow handle and quickly walked into the store. We went to the meat area and grabbed some honey glazed ham and sweet chilly chicken nibbles for dinner. It smelt spectacular and sweet.
