The middle school science investigations came to a close on Friday, May 12 at the Middle School Science Fair where fifteen groups in Grade 7 and nine groups in Grade 6 presented their scientific findings to the school community.
The middle school science investigations are designed to provide students with the opportunity to practice the scientific method… and they quickly learn that it is a messier process than expected! During this hands-on unit that takes place over three months in Semester Two, students work collaboratively in groups of two to four to further refine their skills in problem solving and analysis as well as those essential to working in a lab. These are skills they will build on as they progress through the Science curriculum at Saint Maur and IB. Below are the research questions investigated by the students this year.
- Which type of diaper absorbs the most fluid: infant diapers, toddler diapers or adult diapers?
- How does the mass of borax affect the stiffness of slime?
- How does the environment (light or dark) affect the movement of pill bugs (Armadillidiidae)?
