The purpose of this activity is to recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and students will perform several velocity calculations. Also, students will have to design and build their lander within a pre-determined budget to help reinforce a real-world design scenario.
Students are challenged to design and build wind chimes using their knowledge of physics and sound waves, and under given constraints such as weight, cost and number of musical notes it must generate. They make mathematical computations to determine the pipe lengths.
Convertible Shoes: Function, Fashion and Design
Students teams design and build shoe prototypes that convert between high heels and athletic shoes. They apply their knowledge about the mechanics of walking and running as well as shoe design (as learned in the associated lesson) to design a multifunctional shoe that is both fashionable and functional.
Pointing at Maximum Power for PV
Student teams measure voltage and current in order to determine the power output of a photovoltaic (PV) panel. They vary the resistance in a simple circuit connected to the panel to demonstrate the effects on voltage, current, and power output. After collecting data, they calculate power for each resistance setting, creating a graph of current vs. voltage, and indentifying the maximum power point.
Two Sides of One Force
Students learn more about magnetism, and how magnetism and electricity are related in electromagnets. They learn the fundamentals about how simple electric motors and electromagnets work. Students also learn about hybrid gasoline-electric cars and their advantages over conventional gasoline-only-powered cars.

History Wars: Tommy Douglas Put Canada's Healthcare on the Wrong Path
Did Tommy Douglas put Canada's Healthcare on the wrong path? Canadian historian and award-winning author Michael Bliss and Greg Marchildon, CEO of the Romanow Royal Commission on Health Care, take the gloves off.
The autistic spectrum: from theory to practice
Most of us have a very vague and narrow concept of what autism is, based mainly on such stereotypes as Dustin Hoffman's character in the film Rain Man. In this unit you will discover that there is a wide spectrum of disorders associated with autism, and an equally wide range of approaches to diagnosis and treatment.
3.7 Summary The physiological details of deep or seasonal hibernation vary widely between species. However, the general pattern is similar, involving controlled entry to torpor, with or without ‘test drops’, and periodic arousals. The intervals between these arousals depend on size, T
b and other factors. The frequency of the arousals falls off during the deepest part of the hibernation. Entry to hibernation may be triggered by temperature, daylength and shortage of food, especially

Normal - Mental Status Exam - Frontal Lobe/Executive Sub-exam - Patient 1
Patient is a female with no known neurological health problems who volunteered to act as a simulated patient in order to demonstrate 'normal' responses to exam techniques. She is merely a reference point for exam procedures and protocols, as well as to denote subtle signs from diagnosed patients.
The Story Keepers Bible Easter Story-Part 4 of 9
In part 4 of this animated Easter video, the story of Jesus' betrayal continues to be told. Jesus finds some of his disciples sleeping while He was praying in the garden. Ben and his friends are imprisoned for hiding Christians. This is a wonderful resource for teaching about the Easter story. Content is appropriate for elementary aged students. (6:59)
Eddie and the Hagfish
Hagfish are amazing ocean fishes! They are found nearly worldwide mostly in deeper ocean environments, and are some of the most primitive fishes in existence...
Interactive Panel: The Importance of Being Native In 2011, we saw a resurgence of interest in native code - in C++ in 2011 and in C++11. Is this "C++ Renaissance" a flash in the pan? Is it a long-term trend?
This is an interactive panel. This means you, the attendee in the room or online, will be first class members of the conversation - you drive it. You ask the questions. The theme has been provided. Where do you want to take it? It's up to you.

Breathing Life into History
Rosemary Wells compares and contracts historical fiction with non-fiction, and explains how good historical fiction gets the facts right, but also gives the reader a colorful hero or heroine, someone to walk through history with.

Science Bulletins: Tapping In—The Promise of Brain-Computer Interface
For decades, neuroscientists have sought to use electronics to communicate with the brain. Computing and surgical technique have now become sophisticated enough to implant devices directly into neural tissue. In this feature, researchers at Albany Medical Center and the Wadsworth Center at the New York State Department of Health reveal a world where mind and machine merge. Their cutting-edge devices translate brain signals into action, helping people with ALS and other disabilities regain the ab
