Science Lesson What can teeth tell us? 5E Model #5. Materials #5. Materials

Rationale High-interest, hands-on lesson Follows CA First grade standards This lesson will teach students that teeth have varying shapes and uses

Engagement Show the students pictures of meat- eating dinosaurs and plant-eating dinosaurs, one at a time Ask students to describe the teeth. Ask what kind of food the dinosaur might eat

Exploration Students will work in cooperative groups to investigate the relationship between the shape of a tooth and an animal’s diet Guiding question – How do the teeth of animals help the animals eat their food?

Investigation Distribute materials to each group The staple remover represents sharp, pointed teeth The cotton balls represents meat The 2 flat rocks represent flat, grinding teeth The leaves represent plants

Explanation  Introduce correct terminology  Carnivore – a meat- eating animal  Herbivore – a plant- eating animal  Ask kids to share their findings from the investigation #6. Investigation #6. Investigation#6. Investigation

Elaboration  Extend understanding to new, but similar, situations  Have students use mirrors to examine their own teeth to identify what kinds of teeth they have  They should conclude that they are meat-eaters and plant- eaters
