The main idea is the most important idea that  \nthe writer wants you to remember about the topic. Writers sometimes  \nstate the main idea in a topic sentence. A topic sentence can appear at  \nthe beginning, middle, or end of a piece of writing. Recognising the  \nmain idea can help you understand and remember what you read.  \nSupporting details are smaller pieces of information that tell more  \nabout the main idea. As you read, use supporting details to help you  \nidentify the main idea.  \nRead this passage about looking at stars. As you read, work out the  \nmain idea from the supporting details.  \nStars in other galaxies are very far away. It can take billions of years for their light to reach Earth. By the time their light is visible to us, these stars might no longer exist. They may have collapsed or exploded in space.  \nAlthough we cannot travel back in time, scientists have found a way for us to look at the past. Using telescopes, astronomers can take pictures of stars whose light has just now reached our solar system. Some of these stars are 12 million light years away. A light year is the distance light travels in one year. That means weare looking 12 million years into the past.  \nIs the main idea of this passage stated or unstated?  \nWhich sentence best expresses the main idea of the passage?  Some galaxies are billions of light years away from Earth.  \n We can use telescopes to see very long distances into space.  Some stars no longer exist by the time we see them.  \n Looking at the stars is a way of looking at the past.  \nWrite one detail that supports the main idea.  \nTip  \nWhen the main idea of a piece of writing is not stated, you can work it out by looking at the supporting details. Ask yourself: ‘What idea do all these details tell about?’  \n1  \nMain idea and details  \nIf an author does not state the main idea of a paragraph or an article directly, you can create a topic sentence that summarises the main idea. Ask yourself,‘What idea do all these details tell about?’  \nAs you read this article, think about the main idea.  \nHere is the history of life on Earth as if it had all happened in one 24-hour day, starting at midnight and continuing until it is midnight again. Instead of years, the world’s history is measured in hours.  \nIn this model, Earth was created at 12 a. m. However, the first  living organisms did not appear until approximately 6.30 a. m.  \nFishes appeared at 9.15 p. m.   \nDinosaurs appeared on Earth at 10.50 p. m. but were extinct by 11.40 p. m.  \nThis clock shows 11 p. m., the time when mammals first appeared.   \nPeople first walked on Earth in the last 40 seconds before midnight. All the rest of human civilisation from ancient times until today is squeezed into the very last 0.1 second on the clock.   \nIs the main idea of this passage stated or unstated?  \nWhich sentence best expresses the main idea of the passage?  \n Living organisms have been on Earth for most of its history.  There was life on Earth long before the dinosaurs.  \n Humans have only been on Earth for a very short part of its history.  The history of the Earth can be divided into different sections.  \nWrite two details that support the main idea.  \nRead this article about a famous science experiment. As you read, look for the main idea and supporting details.  \nThe pitch drop experiment  \nby Francesca Bruni  \nThis might not look very exciting, but it is an experiment that has been in progress atthe University of Queensland in Brisbane since 1927.  \nThe very thick goo in the funnel is pitch, which is like the bitumen used to surface roadways. Pitch looks like a solid, but is actually a liquid. The experiment is designed to show that pitch is a liquid, and to demonstrate how slowly it flows.  \nImagine putting your finger under the bottom of a funnel, then filling it with water.
