Testing the Caverns
This lesson 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.
Simple Machines
In this unit, students learn about the six simple machines and are introduced to compound machines. In the first lesson, students learn about work as defined by physical science and see that work is made easier through the use of simple machines. The second lesson introduces students to three of the six simple machines used by many engineers: the inclined plane, the wedge and the screw. Also, students become familiar with each machine's mechanical advantage and how it makes work easier. The thir
New Boxes From Old
Students find the volume and surface area of a rectangular box (e.g., a cereal box), and then figure out how to convert that box into a new, cubical box having the same volume as the original. As they construct the new, cube-shaped box from the original box material, students discover that the cubical box has less surface area than the original, and thus, a cube is a more efficient way to package things.
4.7 Colour
How does the computer's peculiar binary world of digital entities differ from our analogue world of colour, sound, taste and touch? This unit explores the way in which information, in the form of text, still and moving images, and sound can cross the boundary from the analogue universe into a digital world.
Load It Up!
Students take a hands-on look at the design of bridge piers (columns). First they brainstorm types of loads that might affect a Colorado bridge. Then they determine the maximum possible load for that scenario, and calculate the cross-sectional area of a column designed to support that load. Choosing from clay, foam or marshmallows, they create model columns and test their calculations.
Charlotte's Web
As Charlotte uses her web to communicate, the students will also create a web to send a small message. The students will learn how a spider creates its web, and about the different types of webs spiders make. With this knowledge, the students will design and create their own web and incorporate a message.
Sound Booth Construction
Students explore the sound dampening ability of numerous materials by designing and prototyping model sound booths. As a result, students learn about how sound is reflected, absorbed and travels through various materials, thus giving them an overview of sound dampening, energy absorption and sound propagation in the context of engineering. Students also create blueprints and document their findings in a formal lab report.
Preparation of Mammalian Meiotic Chromosomes and Spermatozoa/Obtaining Early Mammalian Embryos and P
This resource is a detailed manual of protocols and instructional information for carrying out an undergraduate laboratory exercise in reproductive and developmental biology, including student outlines, instructors notes, and suggested questions for laboratory reports.
Personal Behavior and Partner's Sexual History:a Simulation of the Spread of HIV
In this hands-on simulation students evaluate factors associated with the spread of HIV. Each student begins the simulation with an "uninfected" solution. They sequentially mix their solution with a variable number of solutions representing potential mates, some of which contain an antigen used to represent HIV. Students evaluate each individual's final solution with a modified ELISA procedure to screen for the antigen simulating HIV. They then use these results to reconstruct the spread of HIV
Immunofluorescence of Cytoskeletal Proteins
This resource provides an introduction for students to the techniques of immunofluorescence.
Getting to the Point
In this lesson, students learn how to determine location by triangulation. We describe the process of triangulation and practice finding your location on a worksheet, in the classroom, and outdoors.
Learning Light's Properties
Students learn the basic properties of light the concepts of light absorption, transmission, reflection and refraction, as well as the behavior of light during interference. Lecture information briefly addresses the electromagnetic spectrum and then provides more in-depth information on visible light. With this knowledge, students better understand lasers and are better prepared to design a security system for the mummified troll.
Park It!
The difference between an architect and an engineer is sometimes confusing because their roles in building design can be similar. Students experience a bit of both professions by following a set of requirements and meeting given constraints as they create a model parking garage. They experience the engineering design process first-hand as they design, build and test their models. They draw a blueprint for their design, select the construction materials and budget their expenditures. They also te
How Much Heat Will It Hold?
Students relate thermal energy to heat capacity by comparing the heat capacities of different materials and graphing the change in temperature over time for a specific material. Students learn why heat capacity is an important property of thermal energy that engineers use in many applications.
