Task

Answers will vary. The task comes from the lesson: On a clear night, with an adult, go somewhere dark, lie back on a blanket and watch the sky for 20 minutes. Count how many meteors you see. Wrap up warm, even in summer!

Look for work that uses the key words correctly and gives a reason for each point.
