Spangler Salutes Emily Pringle
Hamilton Middle School was Steve's latest destination.
Hamilton Middle School was Steve’s latest destination, as he checked out one of the brightest mad scientists in the Denver Public Schools. Emily Pringle has taught in the Denver Public Schools for eight years and uses the scientific method to make the light bulbs come on in the minds of her bright and eager young students.
Ms. Pringle and the kids showed us her candle lab experiment, also known as the “composition of air” demonstration.
Here’s the concept… A candle sits in the bottom of a dish full of colored water. The candle is lit and covered with a test tube or jar. When the candle burns out (because of the lack of oxygen), the water rises in the test tube. Data is gathered as to the volume of water that displaces the air in the tube.
Ms. Pringle’s class concluded from the experiment that 21% of the air that we breathe is oxygen (and the students are correct!). Emily has made quite the impression during her career. We received dozens of emails about the impact she’s had on teaching science and opening minds to the wonder of discovery and experimentation.
