Vacuum Bell Apparatus Ignites Excitement in Chemistry and Physics Students!

My students need a vacuum bell jar apparatus to understand what effect pressure has on sound travel and volume.

My Students

My Chemistry and Physics students thrive on hands on lab experience. I love the excitement that I see in their eyes when they say, "We're doing a lab!". My students come from a variety of socioeconomic backgrounds and ethnicities. My classes contains both gifted and general education students.

Statistics indicate that many STEM based jobs are left unfilled, because fewer students are pursuing careers in science and math.

I hope to inspire students to pursue careers in science and math, and help fill the need for STEM jobs.

My Project

Oftentimes, the topics of gas laws, sound, and fluid mechanics can be dull, and oftentimes challenging, for students to comprehend.

Rather than simply telling my students how pressure and volume are related, and explaining that sound waves cannot travel in a vacuum, I want to show them!

Chemistry students will have the opportunity to operate the vacuum bell and pump in a rotation lab. Chemistry students will experiment and see how objects, such as a balloons and marshmallows, react in a low-pressure environment. Students will understand the conceptual and mathematical relationship between volume and pressure.

Physics students will witness the effect a vacuum has on sound waves and will compare and contrast the difference between mechanical and electromagnetic waves. Physics students will have an opportunity to further their studies on the relationship between pressure and volume in our fluid mechanics unit.
