Crystal Field Theory

High schoolers explore plate tectonics, the "Big Bang" theory and Earth's history through geological evidence. In this understanding Earth's history lesson plan, students complete a 20 question worksheet on the history of Earth including...

Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Want my name and number? It's 6.0221415 times 10 to the 23rd, and my name is Avogadro. Providing nine different activities, experiments, and labs, this lesson keeps Avogadro relevant to your class all year long. 

Only 10 percent of an incandescent bulb's energy is used to create light; the remaining 90 percent is heat. In the unit of activities, young chemists examine energy through hands-on activities, videos, discussions, and readings. Scholars...

Carbon is the most common element on earth, so the innovative discovery of a new type of carbon molecule won the 1996 Nobel Prize. In the ready-to-go lesson, scholars learn about C60 and how it has opened up the entire area of...

What adaptations exist in order for icefish to survive the subfreezing temperatures of the Antarctic Ocean? Middle and high schoolers can find out through watching a related 13-minute video and performing a simple investigation to...

Learners explore the Big Bang Theory and the Theory of Plate Tectonics. In this history of life lesson, students explain two ways the Theory of Plate Tectonics and the Big Bang are of direct benefits to humans.

Students discuss the importance of examining crystals and experiment growing them. In groups, they complete a project in which they use groups in geometry just like crystallographers. They practice solving the groups and proofs and...

Students consider Einstein's theories of Relativity. For this physics lesson, students learn the questions that led Einstein to his theories. Students then create "Einsteinian Thought Experiments" of their own. This lesson includes 3...
