1. INVESTIGATION ONE
BLACK BOXES

2. CONSENSUS
Everyone agrees.

3. COLLABORATION
Working together.
Example: 2 students working on a lab

4. Cooperate Working together but someone is in charge
Example: Teacher and student working together

5. BLACK BOX
Can not be directly observed and easily understood.

6. MODEL
A representation that explains how something is built or how it works.

7. SYSTEM
Parts that work together or share the same space in a meaningful way.

8. CONCEPTUAL MODEL Ideas that suggest what a system is or how it works.
Ideas that exist in a person’s mind or on paper.

9. PHYSICAL MODEL
May be a scaled model, either larger or smaller than the actual system it represents.
It is a model you can touch.

10. Models Scientific models change over time.
When scientists discover new evidence they may decide to change their model.
Scientists make models to help them understand how systems work.

11. HYPOTHESIS
A theory or an educated guess.

12. CONTENT/INQUIRY
Our models were refined by comparing the unknown (original black box) to the known (physical (constructed) models.)
You have a conceptual model when mathematics, words, or diagrams are used to explain how something works or how it is built. The model is not real. It is an idea or a concept.

13. C/I cont.
A physical model is a real model that works and can be tested and compared.
