Preschool Steam Blog from September 13, 2017

Preschool Steam: Biology Beginnings was held today!  Our lesson focused on the differences between living and nonliving things.  

We looked at some National Geographic books while we waited for everyone to arrive.  Then we examined some bugs in critter keepers - two spiders, a stink bug, crickets, a fly, a cicada and a cicada killer.  And talked about the differences between a silk flower in a mystery bag and a real one.  

A quick Sesame Street video helped identify ways to tell if something is alive:  it eats, breathes and grows. We made a collage to reinforce this concept and even learned a song.  And then, it was time to start experimenting!

First, we studied gummy worms.  We looked at them under a magnifying glass, measured how long they were, and identified their color.  The gummy worms didn't move though and weren't much fun so we sprinkled some baking soda on them and put them in vinegar.  That really got them going!

Next we studied real worms.  We looked at them under a magnifying glass, measured them, and identified their color.  But the real worms moved a lot!  And they were fun!  Everyone named their worm and made a home to take home.  

Pictures are below.  Enjoy!
