In this season of thanksgiving, we are grateful to our parent support through the Annual Fund. Students are benefiting from a brand new elementary science lab — a wonderful partner to our middle school lab.
On any given day, you can find students using microscopes, enjoying a mini field trip to identify moss and lichen around campus, or extracting DNA from strawberries in an eighth grade lab.
With the guidance of veteran SHCS science teacher Carrie Templeton, 8th grade students learned to extract DNA from strawberries. Mrs. Templeton shared, “Strawberries are used because they have large genomes; eight of each type of chromosome in each cell. Once the strawberries are crushed, we added a buffer extract: soap helps dissolve parts of the cell membrane and other organelles while salt breaks up protein chains that bind around nucleic acids. The cold rubbing alcohol keeps the DNA from dissolving and makes it visible.”
Of course, all of our students are having a joint STEM (Science, Technology, Engineering, Mathmatics) experience this year through our school “construction project.” It was great to see third graders receive drill bits, limestone, sandstone and soil samples from our construction crew, and to see Middle School math students using architectural plans!
