Introduction
You will be going through websites and viewing some videos to help you understand powers of 10. This will be the basis for understanding our next unit- Scientific Notation.
Task
Make sure to follow the directions precisely and answer the questions on the corresponding worksheet. Sometimes I ask you to stop a video at a certain point, so pay close attention to that. If you need to rewatch a video, please do so. At the end, you will turn in the worksheet to help me see what you have learned from this webquest.
Good Luck!
