Lesson Plans

Name Description

The Surprising World of Complex Systems:

This lesson introduces students to complex systems and to basic concepts from the field of system dynamics that lie at the heart of systems thinking. These concepts include stocks and flows, feedback loops, unintended consequences, and the basic principle that the behavior of complex systems can best be understood by looking at the system as a whole, and specifically by analyzing the system’s underlying structure. The lesson introduces these topics through an immersion in (and a role-play simulation of) the dynamics of urban recycling systems, many of which have been thrown into crisis in the past two years. Through this current-affairs example of complex systems in crisis, we identify some key structural features that help to explain how these systems behave over time. We also discover how well-intentioned action can cause negative unintended consequences when we try to intervene in a complex system without understanding how it operates.

Sea Level Rise: The Ocean's Uplifting Experience:

The purpose of this lesson is to introduce students to the concept of sea level rise as it occurs through climate change by having them examine 3 specific parameters: ice distribution, thermal expansion, and analyzing and interpreting data. The lesson and activities within the lesson were designed using the three dimensions of the Framework for K­12 Science Education and the Next Generation Science Standards – specifically crosscutting concepts, science and engineering practices, and disciplinary core ideas. While there isn’t any required pre­requisite learning required for this lesson, a general understanding of sea-level rise, glaciers, and climate may be beneficial to students. During classroom breaks, pairs of students will develop/discuss their models, revise their interpretations of their models or data, and think-pair-share their thoughts on the investigation segments.

Netting 4 Bugs:

This is a STEM challenge in which students design and create a net to collect macroinvertebrates in simulated streams. Then students analyze the quality of their nets by the amount of macroinvertebrates they are able to collect. After testing, they will redesign to improve their nets. The final test will be done by evaluating a simulated stream's water quality. Students will conduct a simulated bioassessment of a stream by sampling macroinvertebrates and evaluating a stream's water quality using a pollution tolerance index. They learn about the human impact on waterways and the importance of using aquatic macroinvertebrates to monitor water quality.

Medium Needed:

In this MEA, groups of students will evaluate the media for growing plants hydroponically in order to help restore some native species of the Everglades. Students will learn about hydroponics as an alternative agricultural practice, the rock cycle, types of landforms in Florida, and will use different methods to analyze data and arrive to conclusions, as well as present them in a detailed description of procedures and conclusions, including justification and evidence for each decision.

Radioactive Dating: Half-Life & Geologic Time:

In this Model Eliciting Activity (MEA), students must use their knowledge of radioactive dating and geologic time to select an effective elemental isotope to be used to date three rare specimens. This decision requires an understanding of the concept of a half-life and the benefits and limitations of radiometric dating. Students must complete mathematical calculations involving equations and operations with fractions and percentages. Students completing this MEA must develop two essays that respond in a professional manner to a client in the scientific industry.

Time Travelers: Measuring the Age of the Earth:

The student will collect and analyze data, collaborate and discuss their findings, compare their findings to one another, and apply their findings to unknowns. Students will build a timeline based on the masses of substances to develop a basic understanding of absolute age by radioactive dating and how it compares to relative age based on the Law of Superposition. Students will measure the mass of several objects which will represent "fossils." Each object's mass will represent a specific age of the object. Students will gain an understanding of how scientists use absolute dating to accurately determine the age of objects and how relative dating is used to generally determine the age of objects.

Layers and Laws:

The students will identify patterns in fossils and explain their understanding of how rock layers are deposited. They will use the evidence from the activity to make inferences about what the Earth was like during the time the fossils existed. Students will develop an understanding of how fossils give scientists clues as to what the early Earth was like in the past. Students will also show how fossils can be used to relatively date rock layers using the Law of Superposition and index fossils.

Sea Ice Analysis Grade 7:

The changing climate is an important topic for both scientific analysis and worldly knowledge. This lesson uses data collected by the National Snow and Ice Data Center to create and use statistical analysis as a tool to evaluate the sea ice loss. Students will use technology to quickly generate graphs for each month looking for trends, patterns, or deviations over time.

Wolves of Yellowstone - Ecology & Human Impact:

In this MEA, students will decide how many wolves to introduce into Yellowstone National Park's ecosystem. The number of wolves could influence many factors, from the tourism industry to local farming businesses, as well as the populations of other species in the area. Students must choose to introduce the number of wolves they feel will be most beneficial to the preservation of Yellowstone National Park as determined by the mission statement of Yellowstone and the National Park Service.
