Activity 2
Read the text and match the words with their meanings.
Creative inventors have imaginative minds. Scientists have found that daydreaming can lead to creative imagination. It is not related to the task at hand. For example, while working on a math problem, your mind may replay a conversation with a friend, or during a boring meeting, you might find yourself daydreaming about a ball game or something else. Don't worry! This happens to everyone quite often. Moreover, daydreaming can make you more creative and help you have more amazing new ideas. So, keep on imagining and creating! You might just be the next great writer or inventor!
