My Students

"I hear and I forget. I see and I remember. I do and I understand." -Confucius

My students love science, and they especially love the hands-on experiments, projects, and dissection labs.

My favorite part of teaching is seeing their eyes light up when they make a discovery during a lab.

I teach 7th and 8th grade science in a middle school in Missouri. My students are both energetic and inquisitive learners. They enjoy coming to school, researching new science concepts, and conducting hands-on experiments.

My Project

I love teaching using hands on labs and experiments. One of the more difficult concepts I teach to my 8th graders is waves. Waves can be difficult to understand because you can't see sound waves with the naked eye, so they are an abstract concept. A Ruebens' tube is a tube that connects to a gas source. The tube shows many flames, fueled by the gas.

When a speaker is put against the end of the tube, the flames show the sound waves, allowing students to see how different tones and vibrations create different waves.

This visualization helps my students understand how waves work and allows them to see waves in action. The standing wave generator demonstrates how changing the frequency or wavelength of a wave will affect the wave. It is 4 feet tall, allowing a visual of the wave to the entire classroom. These items will help my students to better understand waves and how they work.
