Squishy Eggs, Mealworm Larva and Winning Airplanes

This has been an exciting science month in 4th grade - hands-on science is one of my very FAVORITE things, so I love the amazing science we get to do this time of year.  In the past three weeks, we've had:
*a paper airplane contest that let us practice our scientific method of finding a problem (how to make our planes go further), coming up with a hypothesis, researching it (we love Google!), and then trying it again with improvements.  So fun!
*the addition of mealworms to our classroom.  They will, hopefully, be turning into darkling beetles by the time school is out.  Right now, we are experimenting with them to see if they prefer to live in cornmeal or flax.
*Squishy eggs!  We put a raw egg in vinegar for three days to see what happened to the eggshell if it sat in an acid.  What a fun, stinky experiment!  We're hoping that Mrs. Burgey will put the video of our final squishy egg experiment on BGTV - we tested whether or not it would bounce!
