1 Experimental Procedure: An experimental procedure is a specific set of instructions for conducting a certain experiment.

2 Our Procedure (decreased temperature steps): 1.Insert a watch glass in the refrigerator the day before experimenting to get the watch glass cold. 2.The next day, dry off the watch glass to remove any excess moisture. 3.Place the fortune fish on the watch glass and record its movement and rating using the rating scale. 4.Place another watch glass in the refrigerator for only five minutes and repeat step #4. 5.Repeat step #4 once more but only put the watch glass in the refrigerator for one minute. (Medwid, Emily, et al.)

3 Our Procedure (increase temperature steps): 6. Place a watch glass on a hotplate for five minutes at a setting of 2 to let the watch glass warm up. 7. Remove the watch glass from the hot plate with tongs and set it on a flat surface (like a desk). 8. Wipe the watch glass off with a towel to get rid of the excess moisture. 9. Place the fortune fish on the hot watch glass and record its movement and rating using the rating scale. 10. Repeat steps #6-9 only change the hot plate to a setting of 4. 11. Once again, repeat steps #6-9 changing the hot plate to a setting of 8. (Medwid, Fortune Fish on Warm Watch Glass) (Medwid, Emily, et al.)

4 Materials List: Refrigerator Timer Watch glass Hot Plate Tongs Towel Fortune Fish (Medwid, Hot Plate) (Roventine ) ("Tongs by 3DRivers") (Medwid, Emily, et al.)

5 Rating Scale: 1 Little to no movement at all. - Least Active 2 Curling sides or very small movement. 3 Movement of the head or tail (average movement). 4 Moving head or tail (sufficient movement). 5 Curls up entirely (extreme movement). - Most Active

6 Data Table: Movement of FishRating (1-5) Increase Temperature (Heat) – Hot (8) The fish started shrivel up and melt on the watch glass. The fish did not “work” (tell a fortune) after that. 2 Increase Temperature (Heat)- Warm (4) The sides of the fish moved a small amount as well as the tail curling up. It was a fairly fast reaction. The fish did not “work” (tell a fortune) after that. 3 Increase Temperature (Heat)- Lukewarm (2) The tail curled up first, then the head; ending in the whole body being curled up. Although the reaction was relatively slow. 4

7 Decrease Temperature (Cold) – Coldest (Overnight) No Movement. 1 Decrease Temperature (Cold) – Less Cold (5 minutes) No Movement. 1 Decrease Temperature (Cold) – Least Cold (1 minute) No Movement. 1 Movement of FishRating (1-5) ("The Snowflake: Winter's Secret")
