More than two thousand science and STEM educators participated in the first Science Educators' Best of Show™ Awards by casting their votes for products that they felt impacted science learning.
Similar to many scientific concepts, spectroscopy developed as a result of the cumulative work of many scientists over many decades. We typically credit Sir Isaac Newton with the development of spectroscopy,
Most people have used a microscope at some point during their education, but not everyone has used a spectroscope or spectrometer. While they share similar names, spectroscopy and microscopy are used for different purposes.
Spectroscopy is used for physical and analytical chemistry to detect, determine, or quantify the molecular composition of a sample.
When we consider what defines sound in a physics context, it can be tempting to assume sound is basically vibrations. While partially true, sound is much more complex than simple vibrations.
So what type of wave is sound? Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves.
In physics, sound is produced in the form of a pressure wave. When an object vibrates, it creates sound energy, which causes the surrounding air molecules to vibrate, initiating a chain reaction of sound wave vibrations throughout the medium.
My name is Jonathan Shyu, and I am a student attending Colleyville Heritage High School. For my Advanced Chemistry Research and Design course, I created a biofilter, which is an air filter that uses bacteria in a preprepared compost to process harmful VOC
