Induced EMF in a coil of wire
Students use a simple set up consisting of a coil of wire and a magnet to visualize induced EMF. First, students move a coil of wire near a magnet and observe the voltage that results. They then experiment with moving the wire, magnet, and a second, current carrying coil. Students connect the coil to a circuit and the current from the induced EMF charges a conductor.
This lesson discusses solenoids. Students learn how to calculate the magnetic field along the axis of a solenoid and complete an activity exploring the magnetic field of a metal slinky. Solenoids form the basis for the magnet of an MRI. Exploring the properties of this solenoid helps students understand the MRI machine.
Magnetic Fields Matter
This lesson introduces students to the effects of magnetic fields in matter addressing permanent magnets, diamagnetism, paramagnetism, ferromagnetism, and magnetization. First students must compare the magnetic field of a solenoid to the magnetic field of a permanent magnet. Students then learn the response of diamagnetic, paramagnetic, and ferromagnetic material to a magnetic field. Now aware of the mechanism causing a solid to respond to a field, students learn how to measure the response by l
Working as engineering teams, students design and create model beam bridges using plastic drinking straws and tape as their construction materials. Their goal is to build the strongest bridge with a truss pattern of their own design, while meeting the design criteria and constraints. They experiment with different geometric shapes and determine how shapes affect the strength of materials.
Students learn that wind and storms can form at the boundaries of interacting high and low pressure air masses. They learn the distinguishing features of the four main types of weather fronts (warm fronts, cold fronts, stationary fronts and occluded fronts) and how these fronts are depicted on a surface weather analysis, or weather map. Students also learn several different ways that engineers help with storm prediction, analysis and protection.
Let Your Ears do the Walking
In the previous lesson, students learned about the issue of bycatching by fisheries and how it affects marine habitats. Dolphins are one of the main species affected by bycatching. Dolphins use echolocation to identify the location of objects in the water, but they have difficulty identifying nets, and thus can be caught accidentally. Students will learn how echolocation works, why certain animals use it to determine the size, shape, and distance of objects, and how humans can potentially take a
Does Contact Area Matter?
Using the same method for measuring friction that was used in the previous lesson (Discovering Friction), students design and conduct an experiment to determine if the amount of area over which an object contacts a surface it is moving across affects the amount of friction encountered.
Asteroid Impact is an 8-10 class long (350-450 min) earth science curricular unit where student teams are posed with the scenario that an asteroid will impact earth. They must design the location and size of underground caverns to save the people from uninhabitable earth for one year. Driven by this adventure scenario, student teams (1) explore general and geological maps, (2) determine the area of their classroom to help determine the cavern size required, (3) learn about map scales, (4) test r
Testing the Caverns - Optional
This activity provides a fun, activity-based closure to the Asteroid Impact unit. Students build model caverns using paper mache or clay and bury them in a tray of sand. Next, they test the models by dropping balls onto them to simulate an asteroid hitting the earth. By molding paper mache around a balloon to form a dome, or around a small cardboard box to form a rectangular structure, students will be able to build their caverns.
Forces on the Human Molecule
Students will conduct several simple lab activities to learn about the five fundamental load types that can act on structures: tension, compression, shear, bending, and torsion. In this activity, students will play the role of molecules in a beam subject to various loading schemes.
The invasion has taken place and we need to find a new home. To ensure your survival beyond earth’s occupation you must design a shelter that can be built on another planet. Students will research the characteristics of a planet of their choice. They will design a shelter that will allow them to survive on a new planet, and explain it in words.
In today’s society, there are a number of problems that can be solved through the thinking way of design, or design thinking, from simple designs to large and complex social problems. The goals of this class are to learn the fundamentals of design thinking, as well as to propose solutions to actual problems in the real world. Students are first to learn the concept and methods of design thinking, and then to form groups and propose solutions through actual practices, including field study, re
1 About working with others Very few people study or work in complete isolation. Some courses now set projects and assignments that need to be completed in pairs or groups, either face-to-face or using econferencing. Even if your course does not formally require you to do this, working with others is an important part of your skills portfolio. Most jobs require you to work as part of a team, and employers value individuals who can demonstrate this. In working on a work project or an assignment with others – in p

Boiler Bytes: Students design 'snobot' to clear walks during winter
Mechanical engineering students developed a 'snobot,' a robot running on batteries and sensors, which can remove snow without human involvement. The invention was part of a senior design project.
5.2 Value Added Tax (VAT)
Do you have a graphics or scientific calculator? If so, this unit will help you to understand the different functions and facilities available. With a focus on arithmetic, you will learn what a powerful tool this type of calculator can be.
This Unit will introduce you to a number of ways of representing data graphically and of summarising data numerically. You will learn the uses for pie charts, bar charts, histograms and scatterplots. You will also be introduced to various ways of summarising data and methods for assessing location and dispersion.
1 Using vectors to model
This unit introduces the topic of vectors. The subject is developed without assuming you have come across it before, but the unit assumes that you have previously had a basic grounding in algebra and trigonometry, and how to use Cartesian coordinates for specifying a point in a plane.
This unit focuses on your initial encounters with research. It invites you to think about how perceptions of mathematics have influenced you in your prior learning, your teaching and the attitudes of learners.
