Not even two weeks in, and already we’ve got one eye pinned to the ocular lens of a microscope.
The grade eights of St. Joseph’s Catholic High School have been quick off the mark when it comes to the science curriculum they started work on only days ago. And with a full complement of computer netbooks on the horizon, it would appear that there’s even more momentum building towards the future.
Students are currently studying cells, specifically their characteristics, the scientific theory that surrounds their existence, and the components that make up their internal workings and functions. Also part of this early effort is a good working knowledge of the compound light microscope, the care and control of such equipment, and the identification and implementation of good work and safety habits within the context of a scientific lab.
Yesterday marked the second consecutive day of lab work dealing with the processes involved with dry and wet mounts, the reasons for differentiating between the two, and the manipulation of a microscope to bring into the field of view a specimen with enough detail, and at varying magnification, to sketch a biological drawing with the appropriate headings, labels, and stipple.
Each student had individual access to a microscope, but at the same time was able to take advantage of collaboration with others in an atmosphere of open exploration and discussion within the parameters set by the block objectives. It’s a testament to these students that they were able to carry out all the elements required in such a way as to give the impression that they were more the veteran than the rookie. That being the case, positive success was achieved, the lab was used productively and safely, the equipment was respected and well cared-for, and yes, a fuller and hands-on understanding of cells was achieved.
It’s always nice to have the internet, and video goes a long way to enhancing understanding. But sometimes, there’s no replacement for rolling up the shirtsleeves and getting down and dirty with the subject at hand. Short of a Magic School Bus ride through an onion cell, the grade 8’s are proving that a variety of technologies can be employed in an attempt to better understand the world around them.
