Richard Feynman predicted the periodic table might go up to number 137—but never to 138. Scholars practice naming which elements belong in groups 1, 2, 7, and 0 on the periodic table in puzzles. They work through four puzzles reinforcing...

Mostly what you will find here is a history of quantum mechanics. Influential scientists are introduced (along with some of their recorded quotes), the progression of atomic models is reviewed, and finally experssions and equations are...

This wonderful recap of powerful figures in scientific history includes pictures, important dates, and the information about their inventions or impact. Atomic structure and the photoelectric effect are introduced. The first slide gives...

Electromagnetic radiation behaves like both a wave and a particle. Help classes explore this concept through a lab investigation. Young scientists create optical interference patterns on a glass slide using a carbon layer. They analyze...

Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should notice a...

Here is a six-page script for your biology, chemistry, or physics class to read out loud as a way of investigating nanoscience. This particular lesson is actually a continuation of "Lesson #2 - Nanoscience and Nanotechnology," written in...

Students discover how light reflects off surfaces. In this hands-on demonstration, students examine how variations in color are produced by light interference.

Young scholars are introduced to the topic of light interference through this hands-on activity. They observe how light reflects off two surfaces and then meets to form an interesting variation of color on a film surface.

For this space worksheet, students complete a five question multiple choice on-line interactive quiz about the American space program.

Pupils engage in a study of nanotechnology that is meant to be an enrichment to the already established chemistry curriculum of high school. They are encouraged to make connections to daily life. The lesson includes background...
