What’s the best strategy for cutting down trees? From building houses to burning charcoal, humans have many different uses for wood. Unfortunately, trees are disappearing in many parts of the world, including the older and larger trees that are so critical to the environment.
Students use cylinder volume to determine how the amount of wood in a tree changes as it grows and discuss how communities around the world can harvest (or not harvest) wood in a sustainable way.
Calculate the volume of a cylinder
Before you begin
Students can enter this lesson familiar with the formula for volume of cylinder, or it can be developed during the second question.
How do you increase the horsepower of a car engine? Students calculate the volumes of different car cylinders, and explore ways to make engine even more powerful by changing the dimensions of an engine's internal geometry.
Were megalodons godfathers of the sea? Students model the bodies of different sharks using cylinders, and explore how the volume of a cylinder changes when its dimensions change. They learn that the megalodon was a massive ocean beast, but that its size may ultimately have led to its downfall.
