During
the week of January 23, Mrs. Proudlock's and Mrs. Woolford's seventh-grade
science classes at West Middle School have been studying sound waves.
Their
classes conducted a five-station lab on how sound travels. This engaging
hands-on activity allowed students to experience many principles of sound wave
behavior. Students learned that sound waves need a medium, such as a
solid, gas or liquid to travel through.
Sound
is composed of vibrations carried by waves. Sound travels faster and can be
heard louder when traveling through a solid rather than a gas.
This
investigation by the students was important. Working cooperatively in groups,
students practice clear observation skills. The lab also required communicating
with one another and to politely disagree if necessary.
Employing
the scientific method by hypothesizing and drawing conclusions are vital skills
in and out of the classroom. Teachers appreciated the many positive comments
that could be heard by the students during this lab.
