Scientific Observation: Mystery Tubes
Today students learned that to become a good scientist, you have to make specific and detailed observations so other people will understand what you have found or tested. We introduced the steps of the Scientific Method and learned how to write a great hypothesis, test it, and rework it until their observations matched their hypothesis.
For our activity, students had to make observations about what was happening in a sealed PVC ‘mystery tube’ without being able to see inside. Once they made their observations and wrote a hypothesis to explain what they observed, they worked in groups to build their own working models of the mystery tube. We finished up by talking about why many types of scientists also use models in their studies to help explain a phenomenon.
This lesson was exciting, challenging and great fun to complete. Please try your childs model of the mystery tube yourself to see what we did first hand! Drs. Pearl & Sukow
