Designer Colors, an Inquiry Approach to Flame Testing

Let your physics learners take this electromagnetic radiation exam home to show what they know. You could also use it in class or assign it as a review. The content covers concepts pertaining to color, wavelength, frequency,...

Scientists used flame tests to identify elements long before the invention of emission spectroscopy. Young chemists observe a flame test of five metal cations in the fourth lesson plan of an 11-part series. Individuals then work...

If your electromagnetic spectrum lesson plan has you feeling a little blue, here's a resource that will have you tickled pink! A video from a vast physics playlist describes color from its humble beginnings as a wavelength to its...

Could a virus be the key to reversing color blindness in humans? Some researchers believe so, and have even tested it out on monkeys. Learn more about the experiment and its effects in a short video that could accompany a lesson on gene...

Investigate color, light and excited electrons and produce waves using slinkys. Your high schoolers will observe a continuous spectrum with a prism and an overhead projector. They observe flame tests to identify elements and they observe...

A cell of another color is still a cell. Pupils color a cell to identify its structures in the fourth segment of a seven-segment series. Groups work together to build a three-dimensional cell membrane segment, which is combined with...

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...

Scientists identify elements by the color of flame they produce because each element is defined by exactly one line on the emission spectrum. By completing a series of puzzles, scholars reinforce their knowledge of the results of flame...

Scholars think color-change tests are the best! Show them how to differentiate between alkanes and alkenes using a short video. The narrator guides them through the test and the reactions that occur for alkenes. Other topics include...

Can you eyes be fooled into seeing colors that aren't actually there? Budding scientists view a presentation that addresses this topic. They explore how their eyes interpret color through the retinas and messages sent to the brain. They...
