NGSS Aligned Resources for HS-LS4-2.
Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.

How Novel Icefish Genes Can Improve Health
7th - 12th CCSS: Designed
Designed to accompany the 13-minute video The Making of the Fittest: The Birth and Death of Genes, this handout serves as both a viewing guide during the video and an analysis of how the adaptations of the icefish might help treat some...
The Making of the Fittest: The Birth and Death of Genes
9th - Higher Ed
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...
Got Lactase? The Co-Evolution of Genes and Culture
8th - 12th
Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...
Allele and Phenotype Frequencies in Rock Pocket Mouse Populations
9th - 12th CCSS: Designed
In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...
The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture
15 mins 8th - Higher Ed CCSS: Designed
Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...
The Coelacanth: A Living Fossil of a Fish
4 mins 6th - 12th CCSS: Adaptable
It was just another day of fishing at the local pier when a man unknowingly reeled in a fish thought to be extinct for 65 million years. This short video explains how scientists were surprised to discover that this 360 million year old...
Where Do Genes Come From?
4 mins 7th - 12th CCSS: Adaptable
No, you didn't get your genes from the local clothing store. Learn where they really come from by watching this video as it explores how the genes found in all plants and animals today have arisen over billions of years of mutations from...
How Do Germs Spread (and Why Do They Make Us Sick)?
5 mins 7th - 12th CCSS: Adaptable
Much the chagrin of mothers around the world, germs are everywhere; it's unavoidable. Learn how these microscopic invaders have evolved different ways of spreading from one host to another with this short instructional video.
Why Are Some People Left-Handed?
5 mins 7th - 12th CCSS: Adaptable
Despite what some may think, being right- or left-handed isn't a conscious choice people make. Watch this short video to find out exactly what determines a person's dominant hand, and how the cooperative and competitive nature of humans...
Population Genetics: When Darwin Met Mendel
11 mins 9th - 12th CCSS: Adaptable
Learners explore population genetics, or how populations of species change over time, leading to evolution with a video that brings together the principles of Mendel and Darwin and explains and models the Hardy-Weinberg equation.
How to Live Forever? Be a Jellyfish
5 mins 9th - 12th CCSS: Adaptable
The turritopsis dohrnii, or immortal jellyfish, are tiny, with adults measuring only 0.18 inches tall and wide. The narrator of this short video explores the immortal jellyfish and the importance of their unique and amazing lives. These...
