Discovering Objects

Students learn to interpret museum artifacts, and learn about the history and culture of aboriginal peoples in Canada, by studying objects from the Canadian Museum of Civilization's database, completing a Discovering Objects Activity Sheet, and making a presentation of artifacts.

Grades 5-8.

Treasures of Canada Webquest

Students learn about various themes in Canadian history, including aboriginal history and cultures, French-Canadian history, and immigration to Canada between 1800 and 2000. Working both independently and in small groups, they assume the roles of museum curators of their choice, search the Canadian Museum of Civilization's database, select artifacts for an exhibition targeting high school students, and make a presentation.

A gathering grid can help students organize information for a research report by recording their questions on the left side of the grid and the title of their sources on the top of grid. Then the answers and location of where they're found are filled out in the grid. An example is given.

This art history video discussion examines Antoni Gaudi's Church of the Sagrada Familia or Basilica i Temple Expiatori de la Sagrada Familia Basilica, 1882- (consecrated 2, but still under construction), Barcelona, Spain.

This art history video discussion examines Paul Gauguin's "Nevermore", 1897, oil on canvas (Courtauld Gallery, London).

This art history video discussion examines Paul Gauguin's "The Red Cow", 1889, oil on canvas (LACMA).

In this video, we will demonstrate the function of gears with animations, graphs, and some basic equations. Also, we will cover a few important nomenclatures of gears. The following types of gears will be covered:

1) Spur Gear
2) Helical Gear
3) Double Helical Gear
4) Bevel Gear
5) Worm Gear
6) Hypoid Gear
7) Rack & Pinion
8) Internal [Ring] Gear
9) Magnetic Gear

Also, We will cover some basics of gear designs by covering three related topics of gear profile, gear ratio, and gear pressure angle.
In the end, we will demonstrate all the earlier mentioned types of gear applications in real engineering devices with animations. The applications will be as the following:

a) Hydraulic Pump [Spur gear]
b) Manual Transmission [Helical Gear]
c) Vehicle Differential [Bevel gear]
d) Truck Rear Drive Axle [Hypoid Gear]
e) Conveyor Belt [Worm Gear]
f) Car Steering System [Rack & Pinion]
g) Planetary Gear [Ring Gear]
h) Magnetic Gear Components

Students work as engineers and learn to conduct controlled experiments by changing one experimental variable at a time to study its effect on the experiment outcome. Specifically, they conduct experiments to determine the angular velocity for a gear train with varying gear ratios and lengths. Student groups assemble LEGO MINDSTORMS(TM) NXT robots with variously sized gears in a gear train and then design programs using the NXT software to cause the motor to rotate all the gears in the gear train. They use the LEGO data logging program and light sensors to set up experiments. They run the program with the motor and the light sensor at the same time and analyze the resulting plot in order to determine the angular velocity using the provided physics-based equations. Finally, students manipulate the gear train with different gears and different lengths in order to analyze all these factors and figure out which manipulation has a higher angular velocity. They use the equations for circumference of a circle and angular velocity; and convert units between radians and degrees.

Gears explained. Learn what are gears, driver gear and driven gear, gear ratios, why we need gears, torque and mechanical advantage in this video on mechanical engineering.

A gear is a simple machine that is very useful to increase the speed or torque of a wheel. In this activity, students learn about the trade-off between speed and torque when designing gear ratios. The activity setup includes a LEGO(TM) MINDSTORMS(TM) NXT pulley system with two independent gear sets and motors that spin two pulleys. Each pulley has weights attached by string. In a teacher demonstration, the effect of adding increasing amounts of weight to the pulley systems with different gear ratios is observed as the system's ability to lift the weights is tested. Then student teams are challenged to design a gear set that will lift a given load as quickly as possible. They test and refine their designs to find the ideal gear ratio, one that provides enough torque to lift the weight while still achieving the fastest speed possible.

This simulation introduces gel electrophoresis, a technique used to separate biological molecules. In this simulation, gel electrophoresis is used to separate dyes and visualize them in an agarose gel.

This course includes 8 modules & will take approximately 4 hours to complete in its entirety.

Modules include topics such as:
GSD 101
Understanding the Context
Two-Spirit
Policy
Family & Community Engagement
Transgender Youth

Today we’re looking at how society becomes stratified along gender lines. We’ll discuss Raewyn Connell’s concept of hegemonic masculinities and emphasized femininities. We’ll explore gender socialization in the home, media, and schools. Finally, we’ll explain how gender stratification results in different outcomes by gender in education, occupations, earnings, and criminal activity.

"General, Organic, and Biological Chemistry: A Cellular Perspective" is a textbook designed for a 10-week course in introductory cellular biology and chemistry. This textbook focuses more on the chemical nature of biological and cellular processes than the typical GOB course, which is generally more focused on molecular structure.

This is a textbook on general relativity for upper-division undergraduates majoring in physics, at roughly the same level as Rindler's Essential Relativity or Hartle's Gravity. The book is meant to be especially well adapted for self-study, and answers are given in the back of the book for almost all the problems. The ratio of conceptual to mathematical problems is higher than in most books. The focus is on "index-gymnastics" techniques, to the exclusion of index-free notation. Knowledge of first-year calculus and lower-division mechanics and electromagnetism is assumed. Special relativity is introduced from scratch, but it will be very helpful to have a thorough previous knowledge of SR, at the level of a book such as Taylor and Wheeler's Spacetime Physics or my own text Special Relativity.

Worry and Rumination

While worrying and feeling nervous is something that all human beings experience, as with many things in life, too much of something may not be good for you. Normal anxiety can become a problem when it is excessive, feels uncontrollable, is experienced as intrusive in your life, is persistent (seeming to always be around), and causes you significant distress, or impairs your ability to go about your day-to-day life. This is when normal anxiety becomes generalised anxiety disorder.
One of the important features of generalised anxiety is that the worry and anxiety is spread across a number of different areas such as health, work, interpersonal relationships, finances, and so on. This makes it different from other anxiety problems, such as social anxiety or phobias, where nervousness and worrying are more specific to particular situations.
