## Reflection: Developing a Conceptual Understanding Earthworm Invasion (Part 1/2) - Section 4: Reading a Scientific Abstract

Depending on your students prior experience with experimental design, it may be necessary to remind students about experimental design.  I have found the following questions helpful:

1) What needs to be in each group?

2) What needs to be left out of each group?

3) Where is the control group?

4) Are there more than one experimental treatments?

5) How are the scientists going to determine the results of the experiment?

6) Are the scientists measuring more than one thing?

This video shows a line of questioning that aided one group that was having difficulties identifying the treatments in the experiment.
