Science Lessons from Brown  

scroll to the bottom of the science lessons webpage (PSO: Providence science outreach) above to find the link for homemade ice cream in a ziplock.  it turns out like soft serve.  we did it for co-op and found the secret--lots of ice.  we didn't have quite enough for everyone to be successful  , but even those children whose final product was too soft enjoyed their "milk shake".  this is not for the faint hearted, though, as it takes 30 minutes of real shaking or flipping of the baggie set-up.  below see some tired out co-op participants.  lisa and i walked around and gave the kids short breaks by taking over for them occasionally.
