Demonstrating That Light is Dissipated as Chlorophyll a Fluoresces

Students investigate the spectroscopic colors unique to elements, and to use this information to create a specific color. They follow a detailed schematic to produce a spectroscpoe to be used in the testing.

Need a bright idea for an engaging lab? Watch your class light up as they explore the difference in efficiency between incandescent and LED bulbs! The resource makes use of simple materials and encourages learners to infer what's...

Gummy bears are tasty, but did you know they are also used to determine color and light properties? Use the activity as a way to demonstrate light absorption, light reflection, and refraction with high schooler....

Why can some organisms detect polarized light, but others can't? Scholars observe as the narrator constructs, demonstrates, and explains a simple polarimeter during a video from a larger playlist covering physics. Concepts include how...

Here is a backyard explanation of the polarization of light. Using his porch railing, the video narrator demonstrates that if the grating is lined up with the direction of light waves, represented by a hula hoop, the waves are allowed to...

All this talk about seeing the light... but, what is it, and how do we see it? Science students learn the basics of the nature of light in a narrated video that discusses concepts such as how light behaves, the electromagnetic...

An enlightening installment of the JFR Science series explains the steps for lighting a Bunsen burner. It demonstrates each step in order from collecting the materials to extinguishing the flame.

How can you tell the difference between chemical compounds, when so many of them are white and powdery? The fifth installment in a series of ten videos exposes learners to flame tests and formation of insoluble compounds as methods...

Let the true colors shine through. Pupils conduct a flame test to identify an unknown element. Class members calculate and prepare specific molarity solutions of three chemicals. Using their observations of the colors emitted, they...

Polyatomic ions... where do I begin? One of the most difficult concepts for budding scientists to learn and recognize comes to life in an enlightening resource. Show pupils some demonstrations, via the sixth video in a series of 10, to...
