The Benefits of Biodiversity

Students toss coins to determine what traits a set of mouse parents possess, such as fur color, body size, heat tolerance, and running speed. Then they use coin tossing to determine the traits a mouse pup born to these parents possesses. Then they compare these physical features to features that would be most adaptive in several different environmental conditions. Finally, students consider what would happen to the mouse offspring if those environmental conditions were to change: which mice would be most likely to survive and produce the next generation?

Conflicting Selection Pressures

Explore how populations change over time in a NetLogo model of sheep and grass. Experiment with the initial number of sheep, the sheep birthrate, the amount of energy sheep gain from the grass, and the rate at which the grass re-grows. Remove sheep that have a particular trait (better teeth) from the population, then watch what happens to the sheep teeth trait in the population as a whole. Consider conflicting selection pressures to make predictions about other instances of natural selection.

High School Genetics & Heredity Unit - Phenomena Found in Agriculture

How can we Design Cattle to Better Meet Human Needs? In this high school Storyline unit on genetics and heredity, students are introduced to ‘SuperCows’. As they explore the vast variety of cattle breeds, students discover that cattle are specialized for different purposes and while similar, the ‘SuperCows’ are clearly unique. Students wonder what caused this diversity and specificity which leads to investigations about the role of inheritance, DNA and proteins.

Mice Rule! (Or Not)

Students explore the relationships between genetics, biodiversity, and evolution through a simple activity involving hypothetical wild mouse populations. First, students toss coins to determine what traits a set of mouse parents possesses, such as fur color, body size, heat tolerance, and running speed. Next they use coin tossing to determine the traits a mouse pup born to these parents possesses. These physical features are then compared to features that would be most adaptive in several different environmental conditions. Finally, students consider what would happen to the mouse offspring if those environmental conditions were to change: which mice would be most likely to survive and produce the next generation?

Design Step 2: Research the Problem

Through Internet research, patent research, standards and codes research, user interviews (if possible) and other techniques (idea web, reverse engineering), students further develop the context for their design challenge. In subsequent activities, the design teams use this body of knowledge about the problem to generate product design ideas. (Note: Conduct this activity in the context of a design project that students are working on, which could be a challenge determined by the teacher, brainstormed with the class, or the example project challenge provided [to design a prosthetic arm that can perform a mechanical function]. This activity is Step 2 in a series of six that guide students through the engineering design loop.)

Design Step 3: Brainstorm Possible Solutions

Brainstorming is a team creativity activity that helps generate a large number of potential solutions to a problem. In this activity, students participate in a group brainstorming activity to generate possible solutions to their engineering design challenge. Students learn brainstorming guidelines and practice within their teams to create a poster of ideas. The posters are used in a large group critiquing activity that ultimately helps student teams create a design project outline. (Note: Conduct this activity in the context of a design project that students are working on; this activity is Step 3 in a series of six that guide students through the engineering design loop.)

Creative Engineering Design

Students are introduced to the world of creative engineering product design. Through six activities, teams work through the steps of the engineering design process (or loop) by completing an actual design challenge presented in six steps. The project challenge is left up to the teacher or class to determine; it might be one decided by the teacher, brainstormed with the class, or the example provided (to design a prosthetic arm that can perform a mechanical function). As students begin by defining the problem, they learn to recognize the need, identify a target population, relate to the project, and identify its requirements and constraints. Then they conduct research, brainstorm alternative solutions, evaluate possible solutions, create and test prototypes, and consider issues for manufacturing. See the Unit Schedule section for a list of example design project topics.

Design Step 1: Identify the Need

Students practice the initial steps involved in an engineering design challenge. They begin by reviewing the steps of the engineering design loop and discussing the client need for the project. Next, they identify a relevant context, define the problem within their design teams, and examine the project's requirements and constraints. (Note: Conduct this activity in the context of a design project that students are working on, which could be a challenge determined by the teacher, brainstormed with the class, or the example project challenge provided [to design a prosthetic arm that can perform a mechanical function].)

Designing a Winning Guest Village in the Saguaro National Park

The Challenge Question of the Legacy Cycle draws the student into considering the engineering ingenuity of nature. It will force him to analyze, appreciate and understand the wisdom of these designs as the student team focuses on meeting each of the challenge's requirements. The student is asked, with his team members, to envision a sustainable design for a future guest village within the Saguaro National Park, outside of Tucson, Arizona. What issues need to be addressed to support the comforts of park visitors without compromising the natural resources or endangering the endemic species of the area? A deeper scope of application will reveal extensions of this design in the incorporation of urban planning and systems design. It also strengthens the concept of manufacturing and building without producing waste or pollution.

Implementing Biomimicry and Sustainable Design with an Emphasis on the Application of Ecological Principles

Students are presented with an engineering challenge: To design a sustainable guest village within the Saguaro National Park in Arizona. Through four lessons and six associated activities, they study ecological relationships with an emphasis on the Sonoran Desert. They examine species adaptations. They come to appreciate the complexity and balance that supports the exchange of energy and matter within food webs. Then students apply what they have learned about these natural relationships to the study of biomimicry and sustainable design. They study the flight patterns of birds and relate their functional design to aeronautical engineering. A computer simulation model is also incorporated into this unit and students use this program to examine perturbations within a simple ecosystem. The solution rests within the lessons and applications of this unit.

Energy-Efficient Housing

We all know that it takes energy to provide us with the basics of shelter: heating, cooling, lighting, electricity, sanitation and cooking. To create energy-efficient housing that is practical for people to use every day requires combining many smaller systems that each perform a function well, and making smart decisions about the sources of power we use. Through five lessons on the topics of heat transfer, circuits, daylighting, electricity from renewable energy sources, and passive solar design, students learn about the science, math and engineering that go into designing energy-efficient components of smart housing that is environmentally friendly. Through numerous design/build/analyze activities, students create a solar water heater, swamp cooler, thermostat, model houses for testing, model greenhouse, and wind and water turbine prototypes. It is best if students are concurrently taking Algebra 1 in order to complete some of the worksheets.

Natural Selection in Action: Peppered Moth

Charles Darwin accumulated a tremendous collection of facts to support the theory of evolution by natural selection. One of his difficulties in demonstrating the theory, however, was the lack of an example of evolution over a short period of time, which could be observed as it was taking place in nature. Although Darwin was unaware of it, remarkable examples of evolution, which might have helped to persuade people of his theory, were in the countryside of his native England. One such example is the evolution of the peppered moth Biston betularia. The economic changes known as the industrial revolution began in the middle of the eighteenth century. Since then, tons of soot have been deposited on the country-side around industrial areas. The soot discoloured and generally darkened the surfaces of trees and rocks. In 1848, a dark-coloured moth was first recorded. Today, in some areas, 90% or more of the-peppered moths are dark in colour. More than 70 species of moth in England have undergone a change from light to dark. Similar observations have been made in other industrial nations, including the United States.
