With the change of the semester, 8th grade
students switched from civics to science and vice versa. The new semester has science students honing
their measurement skills. While studying
the metric system, students are expected to compare and convert between units
such as meters, liters and grams.
Students have been busy practicing measuring length, mass, volume and
density. In lab this week, students were
given a real-life scenario regarding a fictitious crime that had been
committed. In this lab they had to
measure and calculate the densities of 9 various substances and observe the
reactions of 3 substances with acetic acid. Students had to select the suspect they
believed most likely committed the crime based on the evidence that was left at
the crime scene as well as analysis of their
data (calculations).
After the conclusion of this unit students will begin
studying experimental design. In the
experimental design unit, they will be challenged to think critically about how
experiments are designed and how new knowledge is acquired. That will lead to the study of chemistry, specifically
the study of matter, the atom, the Periodic Table and chemical equations.
