FOCUS: By summer’s end, nearly every leaf bears some signs of feeding by plant-eaters small or large. Some make holes, some scallop the edges, some roll the leaves into tubes. Plants capture energy from the sun and, in turn, produce food for a variety of leaf-eaters. When we watch a leaf-eater feeding on a leaf – or being eaten by a predator – we are seeing the flow of energy from sun to plant to herbivore to carnivore. These interactions are evidence of food chains and webs, important components of every ecosystem.
INTRODUCTION
Objective: To begin to explore and ask questions about leaf-eaters.
Gather a variety of leaves that have bite marks, spots, or irregularities on them. In small groups, ask children to sort leaves according to their observations.
Materials: a variety of leaves with bite marks, spots, or irregularities.
SORTING LEAF-EATER PATTERNS
Objective: To view examples of leaf-feeding, noticing patterns and grouping by shared characteristics.
Give each small group of children 8-10 leaves from the Introduction, showing damage by leaf-eaters. Alternatively, use a set of photos of leaves showing damage by leaf-eaters (Leaf Photo Set). Continue reading Signs of Leaf Eaters – Activities
