A Lab Demonstration: Three dimensional view of soft internal structures of bony material

College-level or AP chemists use phthalic anhydride to synthesize two different polyesters, one linear and one cross-linked in structure. A detailed materials list and well-written procedures are provided on a lab sheet. Learners write...

Lead your class on an exploration as they locate the center of mass in several oddly shaped two-dimensional objects they create from their imaginations. Pupils also determine the location of the center of mass in three-dimensional...

Cubic crystals can have 6, 8, and even 12 sides. Here is a presentation that shows pupils three different kinds of cubic crystalline structures: cubic, body-centered, and face-centered. These structures are then applied to three...

View attractive, three-dimensional models of an animal cell, a bacterium, or a plant cell. Suspended in a translucent, undulating cytoplasm, are all of the major organelles for life science learners to examine. They can zoom in, click on...

Continue the journey into the world of physics as you lead your class on a winding road complete with vectors and scalers. Pupils learn more about motion, direction, and velocity as they use these concepts to explore two- and...

All mammals have warm blood, are vertebrates, breathe with their lungs, have hair or fur on their bodies, and produce milk for their young. But not all mammals give birth to their young in the same manner. Watch a video that explains how...

A reading of Whale Journey, a fact-filled picture book by Vivian French, launches a study of the life cycle and migration of three generations of gray whales. The interdisciplinary lesson offers opportunities extensions into all subject...

What have our eyes and brains evolved to see? Discover the way our photo receptors and brains assemble visual information into the three-dimensional world we see around us.

A flipped classroom lesson introduces astrophysics fanatics to Kepler's three laws of planetary motion. After reading about the laws of ellipses, equal areas, and harmonies, and also learning how Newton's gravitation concepts come into...

Let's get a closer look at DNA and other molecular structures. The first lesson in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The resource presents...
