1. Fortune Teller Fish Objective:
Today you will be working with a small group of scientists to determine how a “fortune teller fish” works. Be complete, neat, concise, and analytical. Show in writing your ability to THINK like a Scientist! All responses on your paper must be ORIGINAL (don’t work so closely that your reports sound and look alike!) Good luck and remember to SHOW WHAT YOU KNOW!

My personality based on the fish movement:

3. Design an Investigation
2. IQ: What causes the fortune fish to move?
3. Hypothesis: If _____________________, then ____

One criteria of science is that there is a NATURAL explanation for the observations. This means that we cannot use a “miracle” or other supernatural events to explain the fish’s movements.

4. Claim:
The fortune fish works by ___________.
Evidence: relevant observation(qualitative or quantitative)
Reasoning: connect evidence to claim by using a scientific explanation

5. How does the fortune fish work?
It is made of a “hygroscopic polymer” (moisture absorbing large molecule). This material takes up and retains water. When the fish absorbs moisture from your palm or other object that contains water, it responds by moving.
