Slime

Our poor slime mold is either dead or going into hibernation. Two boys with nothing to do took the moldy petri dishes outside to see if they could clean them off, but it got rid of the slime mold too. Both Helga and Luna are hanging in there, so I stuck a piece of paper towel in there to see if we can get them to revert back to the sclerotia mode. The original slime has gone into hibernation, but not on a towel, so I'm debating putting it into a new petri dish to see if I can restart it. 

The 5-6th graders worked with slime today too! Their lab involved mixing various polymers together to see how the characteristics of each thing change. Basically, we made slime. It's a simple lab mixing liquid glue and liquid starch (corn starch, water, borax). Different colors of glue have different results, which is supposed to show them that the glues are made of different polymers. We didn't get that far today. Tomorrow we'll go over our results and draw conclusions!
