Scientists from Praxair, Inc. captured the imaginations of third-graders at Huth Road during a visit by using liquid nitrogen to flash freeze a flower and other objects. The fun and interactive science presentation was led by John Budowski, Sr. Operations Manager and Shannon Lenze, Director of Operations Engineering, whose daughter, Sienna, is in third grade at Huth.
They shared an interactive presentation – complete with an explanation of how atmospheric gases like oxygen and nitrogen are used and how they relate to science topics like photosynthesis, combustion and freezing. Students were able to see scientific experiments with liquid nitrogen. Some lucky students were even able to participate in hands-on demonstrations!
Students were taught important safety procedures to follow while experimenting and then were able to watch how flowers, marshmallows, bananas, gummy worms, and pennies were flash frozen in liquid nitrogen. Students made predictions and saw their hypotheses tested. It was a great way to get the students interested and excited about science and math.
