Scope on Safety : All about asbestos
Asbestos has been used in the construction of elementary, middle, and high school ceilings, floor tile adhesives, pipe and structural beam insulations, science laboratory benches, wire gauss on ring stands, fume hood panels, general insulation, and more during the 1950s through early 1970s. This article will raise your level of awareness to the dangers of asbestos exposure, and describes a series of legislative initiatives developed by the Environmental Protection Agency (EPA) in response to thi
In this workshop session, elementary and middle school teachers explore scale drawing, similar triangles, and trigonometry in terms of ratios and proportion. Besides explanations and real-world problems, the unit includes video segments that show teachers investigating problems of similarity. To understand the ratios that underlie trigonometry, participants use an interactive activity provided online. This is session 8 of Learning Math: Geometry, a free online course.
How high? : measurement (grades 6-8)
With this virtual manipulative, the student investigates conservation of volume with a virtual simulation of pouring a liquid from one container to a container of the same shape, but of a different size. There are four cylinder shapes to choose from: rectangular prism, cylinder, cone, and pyramid. The left container is partially filled with liquid and the base dimensions of the two cylinders are given. The student uses a slider to estimate how high the liquid will rise when poured into the secon
Antarctic Extreme Jeopardy
This Antarctica activity challenges students to research and create the answers and questions for a game of classroom Jeopardy. They will include hazards to humans, polar gear, and the cold facts. This site also includes a series of inquiry-based questions to get students thinking about Antarctica and guidelines for conducting additional research, illustrated activity directions, and a worksheet that helps students craft their Jeopardy-style answers and questions.
Virtual Polyhedra and the Real World
Using computer models, paper, cardboard, wood, and other media, students study and construct three-dimensional polyhedra. Students will learn to identify the platonic polyhedra (tetrahedron, cube, octahedron, dodecahedron, and icosohedron). Students will also learn to describe complex geometric solids in terms of vertices, edges, and faces.
Optical-fibre communications became commercially viable in the 1970s and innovation continues today. This unit will illustrate how very high data rates can be transmitted over long distances through optical fibres. You will learn how these fibres are linked, examine the technology used and assess the future direction of this continually developing area of communication.
Tools and Equipment, Part I
Through a series of activities, students discover that the concept of mechanical advantage describes reality fairly well. They act as engineers creating a design for a ramp at a construction site by measuring four different inclined planes and calculating the ideal mechanical advantage versus the actual mechanical advantage of each. Then, they use their analysis to make recommendations for the construction site.
Normal - Sensory Exam - Cortical (Integrative) 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.

Lassueur Piccardi Graham Little Syndrome.
A rare disease in which cicatricial (scarring) alopecia of the scalp is associated with widespread keratosis pilaris particularly in the axillae and pubic area where scarring does not usually occur. The scarring in the scalp may be clinically indistinguishable from the end stage of other forms of scarring hair loss.
Large bending of a beam
Calculated by VFIFE(V-5), vector form intrinsic finite element. V-5 is developed by Center for Bridge Engineering Research, National Central University, Taiwan. The element is a 3D frame element.

5.5 Energy budgeting – the benefits of hibernation and torpor
Hibernation is an ingenious adaptation that some animals employ to survive difficult conditions in winter. This unit examines the differences between hibernation and torpor, and discusses the characteristic signs of hibernation behaviour. It explores the triggers that bring on hibernation, and whether internal signals or external season cues are predominant. It also examines the physiological adaptations that occur in hibernating animals. This unit builds on and develops ideas introduced in the
Great Britain - Quiz
A six question quiz testing the pupils' knowledge of Great Britain.
3.7.1 Learning is social
What is your experience of work and what did you learn from this experience? This unit will enable you to reflect upon what you have learned from work and support you in improving how you learn at work. It will encourage you to think critically about work-based learning and review your own professional knowledge and skills.
Compare Human-made Objects with Natural Objects
In small groups, students will experiment and observe the similarities and differences between human-made objects and nature. The students will compare the function and structure of hollow bones with drinking straws, bird beaks, tool pliers, bat wings and airplane wings. A classroom discussion can be held to discuss similarities and differences that were observed along with follow up assessment activities such as journal writing and Venn diagrams.
Using their knowledge of physics, students will build a wind chime. Mathematical computations will be done to determine the length of the pipes.
