  1. Oobleck- Allison Reihe http://www.science-house.org/CO2/activities/polymer/oobleck.html

  2. Why does this happen? www.apchem.nagoya-u.ac.jp/image/ouka3.gif Oobleck is crazy like this because of the polymers it in. Well, they are trying to move in the oobleck. If you press this material had and fast the polymers get tangled up and they can’t move. So therefore, if you press this material lightly and slowly, the material will move because the polymers won’t get tangled up.

  3. Purpose The purpose of the experiment is to find out more about cornstarch. www.seed.slb.com/.../cornstarch/images/three.jpg

  4. Hypothesis I think that the Oobleck is going to be a solid and a liquid at the same time. I think this because of the polymers inside this material. www.lbl.gov/.../February/assets/water_solid.jpg

  5. Materials • The things that you will need are: • a disposable container, like an ice cream bucket • water • 1 box of cornstarch • A spoon • A pop sickle stick • a paperclip • Paper towels • newspaper http://sallyrideclub.com/content/20050401.4u2.article.oobleck.jpg

  6. Procedure • place the newspaper down on a table or flat surface • place the ice cream bucket on the paper • Next, add the box of cornstarch to the bucket. • add a little bit of water at first and mix with your hands • add more water if the mixture is to thick • Try different things with the material like hitting it hard and fast, touching it softly and slowly, setting the paperclip in it, setting your hand on the top of the material, and scooping some up with a spoon. Also try and squeezing it in your hand. Then, just let it sit in your hand and see what happens. http://skiptomylou.files.wordpress.com/2007/03/oobleck-2.jpg

  7. Observations I observed that Oobleck is a solid and a liquid. If you hit the Oobleck hard and fast, the Oobleck is hard. If you gently touch the Oobleck the material is in a liquid state. It’s very crazy! http://tep.mit.edu/events/rush/oobleck1.jpg

  8. Conclusions The purpose of this experiment was to find out more about cornstarch. My hypothesis was very similar to the outcome of this experiment. http://cfcp.uchicago.edu/education/explorers/2003winter-YERKES/images/ywi2003-74_large.jpg

  9. If you are planning on saving the Oobleck, do not close the container because mold will grow on it. http://benspartytimelounge.sprayblogg.no/images/oobleck_2_1179427592.jpg
