Our Time Is Up

So our time has come to an end with our science after-school program and it's time to celebrate the students and our accomplishments.  In the after-school program the students learned about about physical science, life science, earth science, and the scientific method.  The students of our program were amazing to work with.  They were engaging and respectful through the whole process.  For our celebration our cooperating teacher had a great surprise for all the students.  She made liquid nitrogen ice cream.  This process is pretty simple but, needs to have safety in mind.  She added half-and-half into a metal pot and a graduate student held the pot with pot holders.  As the teacher poured the liquid nitrogen into the pot the graduate student stirred the half-and-half.  We made a bit of a mess, but after, a while the half-and-half turned into ice cream.  Everyone found this process to be very cool and it was a great way to end our time together.
