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 a set of photos of leaves showing damage by leaf-eaters (Leaf Photo Set). Ask them to look for patterns of similarities and differences and sort the leaves into several groups by the kind of damage they notice. Continue reading Signs of Leaf Eaters – Activities
