Ls2c - Ecosystem Dynamics, Functioning And Resilience

In this video Paul Andersen explains how ecosystems respond to disruptions. Disruptions can cause changes in the number and variety of organisms. It can also lead to migration, extinction or even speciation. Ecosystems that have a higher biodiversity are able to respond to large disruptions over time. A K-12 teaching progression is also included. Intro Music Atribution Title: I4dsong_loop_main.wav Artist: CosmicD Link to sound: www.freesound.org/people/CosmicD/sounds/72556/ Creative ...

Ls2d - Social Interactions And Group Behavior

In this video Paul Andersen explains the importance of social interactions and group behavior. Organisms live in groups because it overs them greater success and has been selected for through natural selection. Some groups are stable and some are fluid. Some groups show an established hierarchy and some do not. A K-12 teaching progress is included.

Ls3a Inheritance Of Traits

In this video Paul Andersen explains the importance of DNA is organisms. DNA contains the blueprint for each organisms. The DNA codes for the mRNA which creates proteins. The DNA also is the unit of inheritance which is passed from generation to generation. A K-12 teaching progression is also included.

Ls3b - Variation Of Traits

In this video Paul Andersen explains how variation is created in a population over time. Variation in offspring is caused by genetic recombination, mutations and environmental effects. Parental DNA is recombined using the process of meiosis. Mutations can add novel genes to a population and the environment can shape the expression of genes. A K-12 teaching progression is also included. Intro Music Atribution Title: I4dsong_loop_main.wav Artist: CosmicD Link to sound: www....

Ls4a - Evidence Of Common Ancestry And Diversity

In this video Paul Andersen describes several types of evidence for common ancestry. This evidence is contained in the fossils, embryos and molecules of living organisms. Even though life on our planet is incredibly diverse there are common threads that run through everything. This idea was most elegantly put forward by Charles Darwin before much of this evidence was gathered. A teaching progression K-12 is also included. Intro Music Atribution Title: I4dsong_loop_main....

Ls4b - Natural Selection

In this video Paul Andersen defines natural selection as differential reproductive success. He then explains how natural selection shapes organisms on our planet through variation and selection. A K-12 teaching progression is also included.

Ls4c - Adaptation

In this video Paul Andersen defines adaptations and explains how organisms can become better adapted to their surroundings using the process of natural selection. Specific examples of adaptations, like coat color in rock pocket mice, as well as a K-12 teaching progression is included.
