According to Harlen (2010) the ultimate goal of science education is for children to have an understanding of relationships, moving beyond science as a series of facts or small ideas towards seeing the bigger picture. Working with a group of 10- and 11-year-olds from a year 6 class, teacher Simon Williams provided a series of challenges using the ecology of the school grounds as a stimulus to help children see relationships in nature. The challenges also supported opportunities for the children to work scientifically by making observations and interpretations from first-hand experience, raising scientific questions from the evidence and using imagination to form hypotheses. Herein, Williams shares how during the nature walk his class found a dead hedgehog, a fungus-covered stick, a twig with unopened buds, and a "tree cave." Back in the classroom, the students observed similarities and differences and formed hypotheses about their findings. Williams concludes by reflecting on the impact this had on his own learning.
