The Microscope and Cell

What a packed lesson! Provide your class with the opportunity to learn about the cell cycle in several exciting ways. Biologists first learn about the theory behind mitosis, then proceed to view onion tips under the microscope and create...

Energize the cells of young biologists with an edible life science activity. Engaging students in exploring the inner workings of plant and animal cells, this activity involves using colored jello and various sweet and tasty treats to...

Life science learners investigate live cells. They examine wet mount slides of cyanobacteria and Elodea plants. They peer into the dynamic microscopic world of protists. Afterward, they construct a model of a cell, including rudimentary...

Use science to solve the mystery of the Poplar murder. Pupils use forensic botany to determine if a suspect could be the killer. By analyzing images from a Transmission Electron Microscope, learners determine if the material found on the...

What do a bird, an egg, a rabbit, and a toad all have in common? This fun-filled resource explains the similarities and differences between cells and how all cells are similar, yet all are different. Learners begin by depicting a...

The differences between prokaryotic and eukaryotic cells are explained and the parts of each are highlighted. Discover the major organelles found in an animal cell and each of their functions. Paul Andersen does an excellent job once...

Adult humans are made of around 40 trillion cells that can't be seen these without some really powerful microscopes! Learners tour both prokaryotic and eukaryotic cells, learning how their structures are similar and different, and then...

It is hard to believe a 300-foot-tall Redwood tree began as a single cell hundreds of years ago. How did it grow so large? Observe how different kinds of cells (bacteria, sex cells, and eukaryotic cells) reproduce or make more cells for...

By exploring the latest research on cell and tissue renewal your young scientists can understand the various internal body parts and systems examined in these studies.

Explain the defense systems of both plants and animals against pathogens with a biology video. It covers the disruption of the immune system through hypersensitive responses, normal responses, nonspecific immune responses, as well as the...
