Population Balance Image Map
Activity 6
The purpose of this activity is to give students a visual on how much energy is taken and lost from the sun and how that energy is transferred between organisms. 
1 liter of Rootbeer (or any other cola)

4 graduated cylinders


Activity 6: Energy Flow in Ecosystems

Teacher Notes:

If you do not have 4 graduated cylinders, you can use just one and pour each measurement of rootbeer into cups.  I recommend clear cups of the same dimensions so the kids can visualize the different measurements more easily.
