Lesson Plans

Name Description
Bonefish Genetics

Recent research has shown that bonefish (Albula vulpes) found all around the Florida Keys, The Bahamas, and many other places across the Atlantic, Gulf, and Caribbean are genetically related. In this lesson, students will learn about what it means to be “genetically related,” how genetics are determined, and how this could change how we manage bonefish populations locally and internationally. They will work together in to create a “model treaty” that protects bonefish between countries.

The Ups and Downs of Populations
Students will analyze population graphs, collect data to generate their own population graph, and experience limiting factors and their impact on carrying capacity in a small deer population. Students will be able to identify, explain, and evaluate the impact that different limiting factors have on the population of organisms including food, water, shelter, predation, human interference, changes in birth and death rate, changes in immigration and emigration, disease, and reproduction.
The Game of Population Changes

This lesson plan uses multicolor paper dots to model how events change a bird population over time. 

"You are a scientist observing a community of birds in the forest. Periodically, different events occur and have an effect on the populations of different birds. As a dedicated scientist and observer, you record all of these changes and watch how the community changes over time."

 

 

Sea Otter Spotter - A Population Growth Curve Using Southern Sea Otter Census Data

Students explore the world of population biology using the sea otter as a case study. The lesson involves reading technical reports from the US Fish and Wildlife Service as well as reading information about the sea otter from non-governmental organizations. Students are introduced to a specialized wildlife capture technique and monitoring of the endangered population through annual census data. Using that data students explore the limiting factors affecting sea otter growth and apply mathematical knowledge to analyze population growth curves. Students also produce an argument on whether the sea otter has met criteria and should be removed from the endangered species list.

Duck, Duck, Growth

In this lab students will have a chance to explore the effects of limiting factors on a pair of ducks. Students will then examine why the limiting factors influences the carrying capacity of a population. Students will collect data and analyze it before drawing a conclusion about limiting factors and carrying capacity.

Dynamics of Populations

This lesson addresses the different factors responsible for the size and dynamics of populations. Growth and decline in population numbers are both addressed through presentation, discussions and a plant growth experiment extension.

To The Limit

"To The Limit" MEA has students identify several factors that can affect a population’s growth. Students will examine photos to list limiting factors and discuss their impact on populations. As a group they will develop a solution to minimize the impact of pollution on fish population.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

Population Dynamics

This 7E lesson plan is broken down into 3 lessons used to teach high school students in grades 9-12 about the characteristics used to describe populations. There are inquiry based and project based inquiry activities incorporated within the lesson. Students will also learn the difference between exponential and logistic growth by doing hands -on activities. A Power Point is used to guide the activities, and learning.

Disappearing Frogs: Percentage and Environment

Students will explore and assess the implications various human and environmental factors are having on the yellow-legged frog population in California. Students will use knowledge of percentages to calculate population size and will complete research to explore the affects of human impact on the environment and the process of adaptation through natural and artificial selection.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem, while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought process. MEAs follow a problem-based, student centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

Text Resources

Name Description
Coral Reefs Show Remarkable Ability to Recover from Near Death

This informational text resource is intended to support reading in the content area. When corals are stressed, they release their algal partners and turn white, a phenomenon called coral bleaching. This occurs when they are under stress from warming waters or other environmental factors. Researchers monitored reefs in the Seychelles during and after coral bleaching events, and found that several factors, including depth of growth, branching shape, nutrient levels, and amount of fish grazing accurately predicted whether reefs were likely to recover from these events. Human impacts such as sediment or nutrient run-off also affect the corals' resiliency.
