Learners reflect on their experiences making silly putty (the previous hands-on activity in the unit), especially why changing the borax concentration alters the mechanical properties of silly putty and how this pertains to tissue...

In addition to the associated lesson, this activity functions as a summative assessment for the Using Stress and Strain to Detect Cancer unit. In this activity, students will create a 1-D strain plot in Microsoft Excel depicting the...

Students use provided materials to design and build prototype artificial heart valves. Their functioning is demonstrated using water to simulate the flow of blood through the heart. Upon completion, teams demonstrate their fully...

Students learn what a pendulum is and how it works in the context of amusement park rides. While exploring the physics of pendulums, they are also introduced to Newton's first law of motion - about continuous motion and inertia.

Learners will discuss the special considerations that must be made when dealing with the human body, and will gain an appreciation for the amazing devices that have improved our quality of life. They will also explore how 'Form Fits...

In this lesson the learners will learn how the heart functions. Students will be introduced to the concept of action potential generation. The lesson will explain how action potential generation causes the electrical current that causes...

This lesson focuses on how food packages are designed and made. Students will learn three of the main functions of a food package. They will learn what is necessary of the design and materials of a package to keep food clean, protect or...

This site explains the arc length. The site has links to related topics and examples.

The online course consists of educational materials about calculus with several variables. Lecture notes, syllabus, exams, and assignments with solutions are included.

This lengthy article offers many examples in its claim that smaller municipalities do a better job of governing and providing services than huge megacities.

In this lesson, students will learn that minerals are a necessary part of our diet. They will learn that different minerals have different functions in the body. More specifically, they will discover that iron is necessary to carry...

Students observe and discuss a simple model of a wet scrubber to understand how this pollutant recovery method functions in cleaning industrial air pollution.

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,...

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...

We are surrounded everyday by circuits that utilize "in parallel" and "in series" circuitry. Complicated circuits designed by engineers are made of many simpler parallel and series circuits. In this hands-on activity, students build...

Students investigate circuits and their components by building a basic thermostat. They learn why key parts are necessary for the circuit to function, and alter the circuit to optimize the thermostat temperature range. They also gain an...

Students work as engineers to design and test trebuchets (in this case LEGO MINDSTORMS robots) that can launch objects. During the testing stage, they change one variable at a time to study its effect on the outcome of their designs....

This lesson covers the process of photosynthesis and the related plant cell functions of transpiration and cellular respiration. Students will learn how engineers can use the natural process of photosynthesis as an exemplary model of a...

This lesson plan culminates the unit with the Go Public phase of the legacy cycle. In the associated activity, students must depict a tumor amidst healthy body tissue using a graph in Microsoft Excel. In addition, students will design a...

Using Avida-ED freeware, students control a few factors in an environment populated with digital organisms, and then compare how changing these factors affects population growth. They experiment by altering the environment size (similar...

Students teams each assemble a wing component of a lifter with the goal to test the lifter wing and measure the force exerted when high voltage is applied to it. After an introduction to torque and its use to measure force, students...

For this lesson unit from the Science Teachers' Association of Ontario (STAO), students fold paper to explore the properties and shapes of materials that give structures their stability and strength. They record their ideas as they...
