Mystery Tubes!

Hello Easton 5th Grade! We were so excited to meet your students! We first talked a bit about ourselves and our science. Mr. Stanmyer described his research on DNA repair, while Dr. Bless explained that she studies the difference between the brains of obese mice and lean mice. Your students had a lot of interesting questions for us! We will be visiting the classroom every other Friday for the year. Each time we come, the students will become scientists with a fun and challenging hands-on activity. Today we reviewed some safety rules and the importance of following directions, respect for others, and teamwork in science.

After all the information was discussed, we jumped into our first activity called Mystery Tubes! The students learned that scientists often use models to learn about a natural or unknown system. A scientific model does not just look like the thing being studied; instead, it behaves like the thing being studied. A good scientific model allows us to test, use, or otherwise manipulate an artificial system in order to learn something about the real system. 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 of how the real tube behaves, they worked to build their own working models of the mystery tube. The students learned another very important quality of a scientist – perseverance! This lesson was exciting, challenging and great fun to complete. Hopefully your scientist shared their mystery tube with you!

Tubos misteriosos Hoy los estudiantes aprendieron que los científicos generalmente utilizan modelos para aprender sobre los sistemas naturales o desconocidos. Un modelo científico no sólo se parece físicamente a lo que estamos estudiando, sino que también se comporta cómo lo que estamos estudiando. Un buen modelo científico nos permite probar, usar o manipular un sistema artificial para poder aprender algo sobre el sistema real. En la actividad, los estudiantes tuvieron que hacer observaciones sobre qué es lo que pasa dentro de un tubo de PVC sellado (el tubo misterioso). Una vez que hicieron sus observaciones sobre cómo el tubo se comporta realmente, trabajaron en equipos para construir sus propios modelos de tubo misterioso. Esta clase fue un gran desafío y muy divertida de realizar.
