Learning Intentions

• We will learn how to calculate surface area, volume and surface area to volume ratios to determine efficiency of an organism.

• We will learn how to describe the impact that the ratio between surface area and volume has on size living things can be to survive

• We will learn how big organisms deal with large surface area to volume ratios.

Closing Task:

You can calculate surface area-to-volume calculations and understand the ratio's impact on an organisms survival
