Learners respond confidently to their desire to learn about natural phenomena; they investigate relationships and solve problems within the context of science, technology and the environment. In this activity, learners will show an understanding of the interrelationships between science and technology, society and the environment.

In this activity exploring difference among vertebrates, the learner will know and be able to interpret and apply scientific, technological and environmental knowledge.
