Explore acid/base chemistry with a demonstration great for the classroom! Students make predictions as to what affect pH has on flower bouquets immersed in different solutions, and then find out if they are right! Originally designed as a high school demonstration, this is safe and easy enough to be used in middle school, or even elementary school. Simply modify how in-depth you explain the science behind the experiment. Perform the demonstration simply as a "mystery science day" with no…

The Planck constant (denoted h, also called Planck's constant) is a physical constant that is the quantum of action in quantum mechanics. Published in 1900, it originally described the proportionality constant between the energy, E, of a charged atomic oscillator in the wall of a black body, and the frequency, ν, of its associated electromagnetic wave. Its relevance is now integral to the field of quantum mechanics.

What is the Bohr Model of the Atom?: The Bohr Model of the atom is a planetary model in which the electrons orbit around the atomic nucleus.
