Can you use THE SCIENTIFIC METHOD AND your senses to solve the mystery of Oobleck? Problem Three liquids are mixed together in a plastic bag. Using your senses (except for taste) can you determine if the substance that is formed is a solid, liquid or gas? Research List three properities of solids, liquids and gases. Solid Liquid Gas Hypothesis I think the substance will be a . (solid, liquid or gas) Thomas Jefferson National Accelerator Facility - Office of Science Education http://education.jlab.org/ Procedure 1. To do this experiment, your team will need: • A plastic bag • A clear liquid • A green liquid • A white liquid • All of your senses, except for taste 2. Open the plastic bag. 3. Carefully measure two teaspoons of the clear liquid into the plastic bag. 4. Next, add two drops of the green liquid. 5. Carefully add two tablespoons of the white liquid. 6. Close the bag and knead the mixture well for 2 minutes. 7. Once 2 minutes have passed, take the Oobleck out of the bag and experiment with it. 8. Record your observations about the properties of Oobleck on the Oobleck Investigation Sheet. 9. Decide if each observation is a property of a solid, liquid or gas. Circle one or more of the State of Matter letters on the right hand side of the Oobleck Investigation Sheet to show what you decided. 10. Answer the blob’s question. What state of matter is Oobleck???

Experimenting with Oobleck is much more than having fun with a weird substance. As students participate in this activity, they will develop important skills in scientific observation. Scientists at Jefferson Lab use a similar process to investigate quarks in the nucleus of the atom. Minimum Materials Needed for Each Student Group: A Ziploc sandwich bag A tablespoon A teaspoon 30 milliliters (2 tablespoons) of a glue-water solution 10 milliliters (2 teaspoons) of a borax-water solution 2 drops of food coloring Optional Materials: Newspapers to cover the desks Small bowls to hold the two solutions Containers to save extra solution Pre-Activity Preparations: The Glue-Water Solution 1. Empty a bottle of Elmer's School Glue into a small container. 2. Add an equal volume of water. 3. Mix thoroughly. The Borax-Water Solution 1. Place 1 liter of water in a small container. 2. Add 60 milliliters of dry Borax powder to the water. 3. Mix thoroughly. Notes: • It is not uncommon for some of the Borax to remain undissolved. • Elmer's Glue-All works just as well as Elmer's School Glue. In addition, we have been able to buy Elmer's GlueAll in gallon containers from home improvement centers. • If kept in sealed containers, the two mixtures can be stored for several months as long as they are mixed well before use.
