Feb. 7-11: Erosion, Geologic Column, & Hearts


February 1-14 is national "Congenital Heart Defect Awareness Week." To be honest, I wouldn't know much about this, except that I work closely with another faculty member who has a son who was born with a major heart defect. She's a great mom who has made it a goal to help others recognize that these problems exist. We're going to have a "Heart Assembly" on Friday where Mrs. Dowdle and Mr. Shaw (both 8th grade science teachers) will talk about their kids who were born under extreme circumstances. I think the kids will find it fascinating - I sure do. Then, during our upcoming Rise and Stretch, I'll be performing a deer heart dissection, thanks to one of the students on our team who donated it for the good of science! (Again... that's a DEER heart, not the student's heart). To learn more about "Congenital Heart Defect Awareness Week", click here.

Other than heart stuff, we're still plowing in to our geology unit.

Monday - Stream (Erosion) Table Observation p6 (students watch weathering, erosion, and deposition in real time!).
Tuesday - Relative Dating & Geologic Column Notes p7 (we learned about how usually older layers of rock are near the bottom of the column, and younger are near the top. However, folding and faulting can play tricks on us if we don't look for them carefully!).
Wednesday - Review and take R&S Quiz on Rock Types & Rock Cycle (igneous... sedimentary... metamorphic)
Thursday - Finish Geologic Column Notes p7 (forces between Earth's plates: compressional, tensional, & transversal).
Friday - Heart Assembly during 3rd, 5th & 6th (excused from 6th - but still need to get the work). Because of how it's worked out, students will come back to class during 4th and work on their superhero mineral drawing.
