Activity Two - Cartoon Strip

Your task is to develop a comic strip to illustrate how the rock cycle occurs. You clearly need to show that the rock cycle does link together.


      1. In the larger segments of your paper draw a diagram of what is happening. Don't forget to include speech bubbles and labels.
      2. Develop a storyline in the 2cm section for each step of the comic strip.


                  • Collect an A4 piece of paper from the classroom
                  • Fold the paper into 8 equal segments (hold the paper in the landscape position and fold in half along the short edge, then fold in half along the long edge and then fold again in half along the long edge).
                  • Open up the paper and you should have 8 equal segments.
                  • Draw a line with a pencil 2 cm from the bottom of the long edge and the same from the middle long divide.
