“Food Webs” explains the movement of energy from producers to consumers to decomposers.

“Types of Mutations” defines and explains the main types of mutations.

The best way to start a study of ecology is to look at the scales of ecology, from the smallest things the field studies, to the biggest. On the small end, ecologists can study individual organisms, as well as populations of those...

Homeostasis explains how organisms maintain homeostasis by analyzing thermoregulation, water regulation, and oxygen regulation.

“Alternate Genetic Crosses” models incomplete, codominance, and multiple allele genetic crosses in order to determine the genotype and phenotype of the possible offspring.

“Life on Earth and Beyond” discusses the origins of life on Earth and explores how scientists classify a thing as “living.”

A video entitled “What Are Genes?” which introduces the concept of heredity, or the combination of genetic traits.

The video “Energy in an Ecosystem” discusses the complex relationship between organisms in an ecosystem, focusing on how small changes can have a large impact.

The video “Selecting a Change” introduces the concepts of natural and artificial selection and discusses examples of each.

A video entitled “Decoding DNA” which introduces DNA and explains the role it plays in reproduction and biotechnology.

A video entitled “Understanding Cells” which introduces cellular biology by discussing the differences between basic cell types and introducing the topic of cell division.

In this Nature League Lesson Plan, Brit explores the definitions and connections between metabolism and aging.

This week on Nature League, Brit Garner explores the rhythms and cycles of life on Earth.

Ever wondered how traits are inherited? How can we predict the height of a pea plant or the color of a flower? Dive into the exciting world of genetics with me, Leslie Samuel, as we simplify complex concepts of genotype, phenotype, and...

And it wasn't the last time we'd break biology either. We were so certain that there were such very particular buckets to put things into, but you probably haven't even heard of some of the weird things organisms get up to. Like...

Why Do Microbes Explode Under UV Light?

This video explores five fun facts about habitats.

This video explores five fun facts about food webs.

This video explores five fun facts about micro organisms.

This video is answering the question of how big are microorganisms.

Evolution “is the net change in organisms or a population over the span of many generations.” This change in organisms or populations happens through DNA mutations and reconbination and is passed down to the next generation through...

This video provides a basic understanding of the different levels of organization in nature, starting from individual organisms to populations, communities, and ecosystems.



This video is part of the 9-part series, Ecology...

This video is a lecture presentation on the process of genetic engineering. The presenter describes and discusses the steps involved in modifying the genome of a bacterium cell, and then evaluates some of the uses and...

We just went over some basics regarding virus-cell interactions, but we have a little more to discuss. We need to understand some more details regarding how viruses interact with multicellular hosts, such as humans. Let's take a look!
