After 90 percent of the town was damaged or destroyed by a tornado, Greensburg, Kansas, and Kiowa County Memorial Hospital developed a Long-Term Community Recovery plan to rebuild for resilience.

With a continued focus on the Sonoran Desert, students are introduced to the concepts of food chains and food webs through a PowerPoint® presentation. They learn the difference between producers and consumers and study how these organisms function within their communities as participants in various food chains. They further understand ecosystem differences by learning how multiple food chains link together to form intricate and balanced food webs. At lesson end, students construct food webs using endemic desert species.
We know that if we take an animal out of its habitat, it will have a difficult time surviving. We also know that there's a lot more going on in ecosystems than just temperature. In fact, there are so many elements in ecosystems, that if just one leaves or gets out of whack, it can be terrible for the whole thing. This video examines how Spider Monkeys are a vital component of a rain forest habitat and what would happen if they weren't part of the ecosystem.
Students review information learned during the past five lessons and activities of the Introduction to Engineering unit. Working in teams, they create flyers and short quizzes about various types of engineering to share with the class and collect into a "Olympic Engineering Binder" for the class to keep.
Air is one of Earth's most precious resources, and we need to take care of it in order to preserve the environment and protect human health. To this end, students develop their understanding of visible air pollutants with an incomplete combustion demonstration, a "smog in a jar" demonstration, and by building simple particulate matter collectors.
Students learn how forces affect the human skeletal system through fractures and why certain bones are more likely to break than others depending on their design and use in the body. They learn how engineers and doctors collaborate to design effective treatments with consideration for the location, fracture severity and patient age, as well as the use of biocompatible materials. Learning the lesson content prepares students for the associated activity in which they test small animal bones to failure and then design treatment repair plans.
In the first of two lessons of this curricular unit, students are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Student teams use spring scales to drag objects, such as a ceramic coffee cup, along a table top or the floor, measuring the frictional force that exists between the moving object and the surface it slides on. By modifying the bottom surface of the object, students find out what kinds of surfaces generate more or less friction. They also discover that both static and kinetic friction are involved when an object initially at rest is caused to slide across a surface. In the second lesson of the unit, students design and conduct experiments to determine the effects of weight and surface area on friction. They discover that weight affects normal friction (the friction that results from surface roughness), but for very smooth surfaces, the friction due to molecular attraction is affected by contact area.
Students use a simple set up consisting of a current carrying wire and a magnet to explore the forces which enable biomedical imaging. In doing so, students run a current through a wire and then hold magnets in various positions to establish and explore the magnetic force acting on the wire. They move the magnets and change the current in the wire to explore how the force changes.
Through a series of three lessons, each with its own hands-on activity, students are introduced to 1) forces, loads and stress, 2) tensile loads and failure, and 3) torsion on structures—fundamental physics concepts that are critical to understanding the built world. The associated activities engage students through experimenting with hot glue gun sticks to experience tension, compression and torsion; the design of plastic chair webbing strips; and problem-solving to reinforce foam insulation "antenna towers" to withstand specified bending and twisting.
Use this activity to explore forces acting on objects, practice graphing experimental data, and introduce the algebra concepts of slope and intercept of a line. A wooden 2 x 4 beam is set on top of two scales. Students learn how to conduct an experiment by applying loads at different locations along the beam, recording the exact position of the applied load and the reaction forces measured by the scales at each end of the beam. In addition, students analyze the experiment data with the use of a chart and a table, and model/graph linear equations to describe relationships between independent and dependent variables.
Students will conduct a number of investigations involving density and buoyancy to understand the forces applied to objects and the resulting interactions among them.
Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time. View a Free Body Diagram of all the forces (including gravitational and normal forces).

Students 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 play the role of molecules in a beam that is subject to various loading schemes.
Historians love to debate each other. So some of them pointed out that the first half of this revolution looks a lot different from the second. Let's chat about industry, cars, and Henry Ford.
-Arson and explosions often present complex and difficult circumstances to investigate due to the fact that the perpetrator has thoroughly planned the act, is not present during the act, and the destruction is so extensive.
-The criminalist’s function is rather limited to detecting and identifying relevant chemical materials collected at the scene and reconstructing and identifying ignitorsor detonating mechanisms.

Forensic Science is the application of the scientific method to solving mysteries. Forensic scientists draw on skills from a number of disciplines in order to gather evidence and draw conclusions about an event. Teachers may use the subject of forensic science to stimulate interest in the various disciplines of science among their students. The discipline is particularly useful in the classroom because it emphasizes hands-on learning and gives students the opportunity to develop their reasoning skills.
Many of the activities on this site use computers and computational science. Such methods are useful to forensic scientists because they allow scientists to view evidence with greater clarity, to simulate specific events and to save time by automating tedious processes.
This site covers everything you wanted to know about forensics in Canada, from forensic science to medical examiners.
This student material on forensics covers the following:
