These are the smallest energy spacings, and their size can be understood by comparing the energy of a diatomic molecule with internuclear spacing ~ 1 Å to the energy of a valence electron (estimated above as ~ ħ/a). [1] Actual molecular spectra also show transitions which simultaneously couple electronic, vibrational, and rotational states.
John Tyndall was also influential in the teaching of physical science. [3] In the United States, science education was a scatter of subjects prior to its standardization in the 1890s. [4] The development of a science curriculum emerged gradually after extended debate between two ideologies, citizen science and pre-professional training.
[1] [2] defines the structure and content of an academic course. It splits an often-multi-year curriculum into deliverable units of work, each of a far shorter weeks' duration (e.g. two or three weeks). Each unit of work is then analysed out into teachable individual topics of even shorter duration (e.g. two hours or less).
[1] [2] [3] A more fundamental statement was later labelled as the zeroth law after the first three laws had been established. The zeroth law of thermodynamics defines thermal equilibrium and forms a basis for the definition of temperature: if two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium ...
The channel produces a range of videos that touch on various concepts related to science and technology. [1] AsapScience is one of the largest educational channels on YouTube. The channel was created in May of 2012 and had acquired more than 7 million subscribers by March 2018. [2] [3] This following had increased to 9 million by 2020. In ...
Experiment using two tuning forks oscillating at the same frequency.One of the forks is being hit with a rubberized mallet. Although the first tuning fork hasn't been hit, the other fork is visibly excited due to the oscillation caused by the periodic change in the pressure and density of the air by hitting the other fork, creating an acoustic resonance between the forks.

A lesson plan is a teacher's detailed description of the course of instruction or "learning trajectory" for a lesson. A daily lesson plan is developed by a teacher to guide class learning. Details will vary depending on the preference of the teacher, subject being covered, and the needs of the students .
