Reports usually appear in newspapers. They tell readers about events that have been happening in their local area, or national or international news. Newspapers are read by people who want information about something that has happened. They want details quickly so reports have to be easy to read and have a snappy presentation style.
Chose a historical event that interests you and do some research on it. For example, you might be interested in the day Neil Armstrong walked on the moon, or the day events that took place at the Olympics this year. Think about how you could turn your research into an interesting news article. Use the brainstorming page to help you organize your ideas.
