Dear Students of Ms. Kozakiewicz’s Class,

Here in Washington DC, the National Aeronautics Space Administration has learned about what a stellar group of thinkers you are. We have been told by reliable sources that you are trusted to be involved in making keen observations and wonderful discoveries. Frankly, we need your help. Recently a space probe, while searching for evidence of water on a particular body in space, located a large green ocean. Naturally, samples have been carefully collected for analysis. Our organization has named the substance “Oobleck.”

Our introduction studies conducted by chemists indicate that:

• Oobleck is safe to handle; there is no need to be afraid. As with all chemicals, DO NOT TASTE!
• Residue should be brushed carefully into garbage can; never pour down a drain.

As a group:

ü Brainstorm the different properties about Oobleck.

ü Closely examine Oobleck with your senses, except taste. Ask your teacher for tools you would like to use.

ü Complete an extensive list of descriptive properties, and how Oobleck responds to different conditions.

ü As a group decide if Oobleck is a liquid or a solid.

ü Explain your answer intelligently!

Stay at your station during the entire session. As a class you will discuss your observations after the Oobleck has been safely put away. We are eagerly looking forward to your good work. Thank you for your capable assistance in this important “matter.”

Sincerely,

Ms. Thixotropic

Chief Oobleck Chemist
