4RJ and 4G performed an experiment to test what happens when a can of diet coke and a can of coke are placed in a tank of water.  We discussed the results in terms of mass, volume and density.

Next class we will put a twist on this experiment.  What variables can be changed in this experiment?  "Comment" with your ideas below!  We will choose several ideas to test during the next class!

Take a look at the graduated cylinder above.  What is the volume of the blue liquid?  How did you come up with the answer? 

Comment and post your answer below!  If you are having an issue "commenting," write your answer down and bring it to science on Wednesday.

S.C.A.M.P.E.R.

Ask your 3rd grader to tell you about the acronym, SCAMPER.  Scamper is a creative problem solving technique that the third grade students will be employing during the time leading up to the Invention Convention, to make improvements to products that already exist!

SCAMPER:

S-Substitute: What part of the object may be replaced by another thing?  Can you swap the material that the object is made of?  Can you use the object in a different way?

C-Combine: What can you bring together?  What might work well together?  What materials can you combine?

A-Adpat or Adjsut: How can you adjust or adapt the whole object, or part of the object?

M-Modify: What changes can you make to the size, shape, color, texture, or taste of the object?

P-Put to Other Use: In what other ways can you use the object?

E-Eliminate: What could you subtract, take away, or do without?

R-Rearrange or Reverse: Can you reverse the object or parts of it?  Can you turn the object around or inside out?

Ooh Oobleck

Yesterday, 4G finally got to experiment with the non-Newtonian fluid, Oobleck! It looked like a container of cornstarch exploded in the science room, but an interesting and fun time was had by all!

Recipe:
Mix 1 cup water with 1/2 cup cornstarch
