LESSON 2 – TEETH

LO: to compare teeth of animals Recap: What are the 3 types of teeth. What shapes are they and what they are use for?

LO: to compare teeth of animals Incisors: These are our front teeth and used for pulling and tearing food. Canines: These are the teeth that are used for gripping food and tearing meat. Molars: These are used for grinding food.

LO: to compare teeth of animals What is a carnivore? An animal that feeds on other animals either predators or scavengers (meat eaters). Can you think of 2 examples? Lions, crocodiles

LO: to compare teeth of animals What is a omnivore? Can you think of 2 examples?

LO: to compare teeth of animals What is a omnivore? An animal that has the ability to get its energy and nutrients from eating both plants and animals. Can you think of 2 examples? Humans, mice

LO: to compare teeth of animals What type of teeth do each of these groups have? Carnivore Canines Herbivore Incisors and/or molars Omnivore A mixture of all Why might this be? Think of their diet

LO: to compare teeth of animals Carnivores Most carnivores have long, sharp canine teeth adapted to ripping, tearing or cutting flesh which are their most important teeth. While many also possess a few molars in the back of their mouths, and may also possess sharp incisors in the front, their canine teeth are very pronounced.

LO: to compare teeth of animals Herbivores typically have chisel-like incisors and large, flat premolars and molars for chewing plants.

LO: to compare teeth of animals Omnivores Humans are omnivores, meaning we eat both plants and animals, and our teeth have evolved to suit our diet. Our canines are smaller than a carnivore’s and we have flat molars to help us chew our food before swallowing, as plant material needs grinding before we can digest it.

LO: to compare teeth of animals Your task: • Copy the table on the previous slide. Draw or cut out the pictures on the next slide and stick them on the left hand side of your table. • Say whether their teeth are mostly molars, incisors, canines or if they have a mix of each. • Then write next to it what type of animal it is: herbivore, omnivore or carnivore. • Add 2 -3 more of your own choice of animal (just write the name). Extension: Choose one animal and write a short comparison on how our teeth are different to that animal and why.
