Re-watch the video and focus on the scene where the boy looks at the beach. What has happened? Why has this happened? What does this mean for the ocean? How can it be prevented? Can you design your own poster to command people on the beach to do the right thing? You can present your poster using paper, crayons, paint or using the paint package set as a 2Do on Purple Mash.
Watch the video below and try the activities so you know how to write command sentences.
