Step 2 Learn about the spidergram
1. Learn to organize ideas

S:
Clothing | Food | Housing | Transport |
People would have to wear special boots to prevent them from floating off into space. ..... | Plants couldn’t grow. People would have to eat dried food. Food would be in the form of pills and would not be so tasty. ... | Air is provided at home. They need sleeping bags to keep them in place while sleeping. Humans could live in houses with huge comfortable rooms ... | Everything will float in the air. Traffic would not be so heavy. ... |
T: Look, this is a spidergram. It can help us organize our ideas better.
