Science challenge is a key strategy for bringing the Adaptive Dimension to the classroom, and for encouraging independent learning. Prizes or points could be awarded for greatest mass supported, mass supported to mass of structure ratio, innovative design elements, imaginative use of coloured paper for visual effect, tallest structure, completing project on time and within budget, minimum mass of paper and glue used to meet design criteria, and so on. There is no single topic at the elementary level that is a direct precursor to this unit. Many life experiences have prepared students to consider the topics raised in this unit. Veins are the structural support for the photosynthetic tissue of the leaf.
Stems are the structures which support the leaves so that they are exposed to the sun.
Skeletons of both vertebrates and invertebrates give their bodies form and act as attachment sites for muscles. The physical properties of different types and states of matter are crucial when considering building materials. This unit provides an excellent opportunity to consider some of the technological achievements which shape our society. Foundational and learning objectives for Science and the Common Essential Learnings Recognize elements of design in a diverse group of objects. Discuss why structures are constructed.
