Which aspects of your maps have theoretical “pieces” (not directly observable)?

Which aspects of your maps have theoretical “pieces” (not directly observable)?

• Entities (things)or processes that are: – too small (atoms, molecular motion), – too large (the universe), – too fast (speed of light), – too slow (evolution, plate tectonics), – too inaccessible (the middle of the earth) to observe directly by the senses or measure directly with instruments.

• Theoretical things can also include abstractions (like magnetic fields, gene pools).

• Did you find that the mapping was a product of your ideas, or that it helped you generate ideas?

DebriefDebrief• Makes thinking explicit• Makes thinking “sharable”• Helps to organize thinking• Helps you “see” relationships• The map is flexible, can be easily revised

• Helps non-verbal kids contribute to the thinking of groups

• 1. In your groups of 3, select a member to find and read one Web resource on thermal pollution, one member should find and read one Web resource on fish respiration and one member find and read one Web resource on the chemistry of dissolved oxygen in water. These resources need only be “introductory level” – ranging from one to three pages in length.

• 2. Develop a testable question based on your representation that will help you understand a little more about processes, entities, involved in goldfish respiration.

• 3. Describe what theoretical entities, processes or properties this question will help you learn more about.

• 4. Bring to class Thursday a print-out of your group’s model from Wednesday with the question and the description of the processes you will learn more about.

• And finally, please remember that in our work with the goldfish, that we must respect these animals as living things. We must avoid unduly stressing these animals. Goldfish have been specially bred for low oxygen environments. Being in low oxygen environments for short periods of time does not damage or stress them excessively, but we will want to be vigilant about moving them too often, leaving them in unusual conditions for more than a few minutes, etc.
