In this video, students will learn about the distribution of species throughout different geographical areas, biodiversity, and species evolution.
The video aims to answer the question: How does biodiversity occur?
Teaching Tips
Positives
The video includes graphics and on-screen text to support student understanding.
There is a time-stamped transcript that allows students to easily follow along.
Additional Prerequisites
Students should be familiar with basic ecology concepts, including evolution, species, and habitat.
Differentiation
Two questions are posed at the end of the video that can be used to guide further student investigation.
The on-screen text can assist students in taking notes throughout the video.
Students can create a graphic organizer, such as a concept map, to consolidate the information from the video.
Because the video is long and detailed, teachers should consider pausing the video occasionally to discuss the concepts presented and answer students' questions.
Scientist Notes
The resource is appropriate to introduce students to Biogeography, species distribution pattern over space. This is recommended.
Standards
Next Generation Science Standards (NGSS)
ESS2: Earth's Systems
HS-ESS2-7 Construct an argument based on evidence about the simultaneous coevolution of Earth’s systems and life on Earth.
LS2: Ecosystems: Interactions, Energy, and Dynamics
HS-LS2-2 Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.
HS-LS2-6 Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.
HS-LS2-7 Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.
LS4: Biological Evolution: Unity and Diversity
HS-LS4-4 Construct an explanation based on evidence for how natural selection leads to adaptation of populations.
HS-LS4-5 Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species.
