Photosynthesis: Math Lesson

Wrap-up:

Graphs and numbers are not just random markings on a page; they tell a story. Here they helped tell the story of the rise of carbon on our planet. We may not be able to see carbon dioxide with our naked eyes, but we can see the rise and fall of CO₂ in years and years of data drawn out on a graph.

In this lesson you:

• Analyzed graphs of carbon dioxide levels over time and find patterns in the data
• Examined maps and graphs of carbon dioxide output around the world
• Calculated how much carbon plants store through photosynthesis

On your own:

• Keep track of your household carbon footprint at the with the EPA Household Emissions Calculator
• Learn about ways to reduce your carbon footprint (and save money) by using less electricity and using it more efficiently
• Search the internet to find out more about the energy it takes to grow your food, and how much carbon dioxide is released in the process
