Slime!

As many of you probably heard, we made slime in class yesterday.  Our science lesson focused on observing properties.  We used our senses of sight, smell and touch to observe the properties of corn starch and water (tinted green!).  Next, we made a hypothesis for the properties of a mixture of the two.  We mixed them up, and were amazed to see what happened!  We compared our hypothesis with what actually happened during our experiment.  Unfortunately, I was so involved in slime I forgot to take pictures of our mixture, but you can make slime at home too.  It's a little messy, but cleans up easily.

To make slime, you need corn starch and water.  I used about 2 parts corn starch to 1 part water.  I added food coloring to the water before mixing with corn starch.  You may have to add more corn starch or water, a little at a time, to get the right consistency.  Corn starch slime is great, because its properties change!  You can make it into a shape if you keep moving it, but hold it still and it will ooze!  Please ask your child about his or her slime experience :-)
