3. Young Woman - Examine this young woman until you see her change. (View image on the web).

4. Two Tables - Examine these tables. Test your hypothesis. Record your data in the space on the right.




5. Moving Stillness - Examine the image on the web. Sit close to the screen and look into the image. Record your observations below.  Moving Stillness.






6. Blackdots - Examine the image on the web. Look for black dots at the intersections. Are they real? Record your observations below. Black Dots.




7. TriZone Space Warper - An illusion created by magician and inventor Jerry Andrus. TriZone Space Warper from YouTube.
Build your own Space Warper (optional). Record your observations below.





8. Audio Illusion - Listen to the sound file and record your results, and the class results. Use "A" for ascending, "D" for descending.   The Tritone Paradox Illusion

Part II. The Brown Box.

Making Observations

You will be given a sealed, brown cardbox box. The box contains an ordinary,  common item. The goal is to make careful observations and then to develop inferences (conclusions) from these observations. Many of the boxes have an identical or similar item in another box. Some boxes have unique items. A second part of this exercise is to find the other boxes that have the same or similar item as yours (if possible). We will examine the boxes for about 15 minutes. During this time, you should perform "experiments" on the box, recording the "experiment" and the results. (Shaking the box is one sort of experiment).
Record your "experiments" in the following table.


 Describe the action taken
 Describe the observations (no conclusions!)
