Teachers, brainstorm with your students the variety of sciences that your students know about. On the left side of the board or on a large sheet of paper write down their contributions (biology, geology, hydrology, mycology, physics, eolian science, ornithology, etc.). Have them contribute at least 12 sciences. If they need assistance, give them hints. After the list is complete, have each student arrange the words into an organizational chart. They can make concept maps or 'family trees' of the words: draw lines between the sciences to show relationships, make sets and subsets of their words, or create an organizational chart in any way that makes sense to them.
When students have finished their organizational charts, choose one student to share his or her organizational method on the board or large piece of paper. Help them understand that this student's organizational chart is only one of a number of ways that the words can be organized logically. Perhaps ask for a second example of how a to organize the sciences.
Have the class discuss the relationships between the sciences described by the student. Have other students contribute additional relationships. Why is important that all the sciences are related in one way or another?
