Jefferson 7th Graders Receive Refresher on Using a Triple Beam Balance

Jefferson Middle School 7th graders in Matt Turecek’s science class received a back-to-school refresher in the use of a triple beam balance, which is a type of scale commonly used in the laboratory to determine the mass (by weight comparison) of samples. To use the balance, you use sliding weights called riders on three beams, each with progressively small incremental amounts.

Students learn about the triple beam balance in 6th grade but Mr. Turecek gave students practice exercises in preparation for more difficult science experiments (for example, density) that they will be conducting this year in physical science. Experiments in seventh grade also use a higher level of math skills, which the students also prepared for in this beginning of the year exercise.
