The following lesson is one based around the use of lego's. This lesson's overall goals are to facilitate understanding of the importance of precise communication in science and to be able to create models without a direct understanding or concept that can be directly observed.

The objectives of this lesson are for students to develop precise communication skills and for students to begin thinking about why scientists use computer models to study concepts that are not directly observable.

In this lesson students will attempt to describe the architecture of a lego structure to another group of students who have not seen the structure in order to build a duplicate, identical structure. Note that this lesson uses four groups of students but any even number of groups will work, given that there are enough legos for each group.
