Different shapes, different jobs
1 · Learn
Incisors at the front help bite and cut. Canines have more pointed shapes that can help tear. Premolars and molars have broader surfaces that help crush and grind.
A person's teeth change while they grow. Do not assume everyone has the same number of visible teeth at the same age. Compare structures respectfully using diagrams.
2 · Worked example
A broad back tooth is well suited to grinding because of its surface shape. I connect shape to function rather than learning only a label.
3 · Your turn
Which teeth are generally well suited to grinding: incisors or molars?
Check your answer
Molars, because their broad surfaces help crush and grind food.
4 · Apply your learning
Use an accurate labelled model to locate tooth types. Compare adult-selected images of herbivore and carnivore teeth cautiously.
Adult guidance and safety
Do not inspect classmates' mouths or use sharp objects on teeth. Personal dental questions belong with a responsible adult and dental professional.

My observation notebook
With an adult, look at a safe real example or a checked photograph. Name the example and say which you used. Record what you actually notice. Do not taste plants or materials, approach unknown animals or invent missing observations.
Ask your teacher for support with the method and recording. A prediction is what you think might happen; an observation is what you actually see, hear or feel safely.
Keep your notebook: use Download notebook before leaving. Nothing is sent to the website or saved to your account. Reopen the downloaded notebook here to add another day's record. Do not include names, addresses or other private information.
