Lesson one of the year 8 unit - Planet Earth. Suitable for low-mid range year 8 group. Grades are 1-9. Presentation takes students through the structure of the Earth through various activities. I have adapted the worksheet from this one. I use Triptico for some of my activities. I highly recommend this resource - lots of fun little activities. If you do have an account, feel free to message me with your username and I shall add you to my shared group so you can have the activities too.
