Activity 2.1: Predictions About Patterns in Ecosystems (30 min)

Resources Provided

Setup

For Activity 2.1, open the 2.1 Predicting Patterns in Ecosystems PPT and project it. Prepare enough copies of the 2.1 Predictions Tool For Ecosystemsfor each student to have one.

Directions

1. Introduce the activity.

Open 2.1 Predicting Patterns in Ecosystems PPT. Use Slide 2 to remind students about meadows.

Assessment

Ideally, the discussion about the Predictions Tool in this activity will reveal a range of student ideas. Level 4 students will realize that the biomass of producers must be much larger than the biomass of herbivores, which, in tu will be much larger than the biomass of carnivores. Level 2 and 3 students may assume that the biomass of producers, herbivores, and carnivores may be more equal or have other ideas about biomass patterns in ecosystems.
