Fifth Grade Science Fair Project Ideas
Please use Google Classroom to complete your Solar System Projects.  You can do your report using Google Slides and find examples of how to build your Solar System model.  Remember, you will be given three grades: (1) Model (2)Slide show presentation (3) Oral presentation.  The date due and the Rubrics being used to grade you, are all under Science: Solar System Projects.
                                     Making Slime
The glue has an ingredient called polyvinyl acetate, which is a liquid polymer. The borax links the polyvinyl acetate molecules to each other, creating one large, flexible polymer. This kind of slime will get stiffer and more like putty the more you play with it. Experiment with different glues to see if they create slime (e.g., carpenter glue, tacky glue, etc.).

More Information about non-Newtonian Liquid

A non-Newtonian liquid is a substance that acts like a liquid in some situations but as a solid in others. Quicksand is an example of a non-Newtonian liquid. It appears to be solid, but if you stand on it, you slowly start sinking as if it were a liquid.

Polymers are what make non-Newtonian liquids unique. A polymer is a long string of molecules which can exist as a liquid or a solid. The
term polymer comes from the Greek words for “many parts.” Liquid polymers act as a liquid until particular chemicals are added, which create links between the molecules. These links transform the compound into a hybrid between liquid and solid. Since the molecules are now connected, they cannot move as freely, which gives them the strange properties found in slime. The new compound is called a non-Newtonian liquid.
