Does Weight Matter?
Using the same method for measuring friction that was used in the previous lesson (Discovering Friction), students design and conduct an experiment to determine if weight added incrementally to an object affects the amount of friction encountered when it slides across a flat surface. After graphing the data from their experiments, students can calculate the coefficients of friction between the object and the surface it moved upon, for both static and kinetic friction.

Analyze the Data
Students go through the logical process of quantitatively analyzing data from the FasTracks system. They gain experience identifying problems with the current design based upon their earlier observations and experiences in activities 1 and 2. Students discuss the flaws that they find in the system. This activity requires the use of the FasTracks Living Lab, a web portal to interactive train (transit) traffic data for a major metropolitan city.

What Do Bread and Beer Have in Common?
Students are presented with information that will allow them to recognize that yeasts are unicellular organisms that are useful to humans. In fact, their usefulness is derived from the contrast between the way yeast cells and human cells respire. Specifically, while animal cells derive energy from the combination of oxygen and glucose and produce water and carbon dioxide as by-products, yeasts respire without oxygen. Instead, yeasts break glucose down and produce alcohol and carbon dioxide as th

Seismic Waves: How Earthquakes Move the Earth
Students learn about the types of seismic waves produced by earthquakes and how they move the Earth. The dangers of earthquakes are presented as well as the necessity for engineers to design structures for earthquake-prone areas that are able to withstand the forces of seismic waves. Students learn how engineers build shake tables that simulate the ground motions of the Earth caused by seismic waves in order to test the seismic performance of buildings.

Newspaper Tower
Students will be challenged to design and construct a tower out of newspaper. They will have limited supplies including newspaper, tape, and scissors since engineers are often restricted by economic reasons as to how much material they can use in their building. The students will be building for height and stability, and their towers must be designed to withstand a lateral “wind” load.

Bombs Away!
Students will design and build a device to protect and accurately deliver a dropped egg. The device and its contents represent a care package that must be safely delivered to people in a disaster area with no road access. In a similar fashion to a team of design engineers, students will design their devices using a number of design constraints including limited supplies. The activity emphasizes the change from potential energy to kinetic energy of the device and its contents and the energy trans

We've Got the Power
In this lesson, students will research various sources of renewable energy. They will discover how each source can be used to generate electricity, the potential benefits and drawbacks of each and which source might best power their home or school. This lesson can be completed in 1-2 class periods.

Multicultural Math Fair
This website provides a collection of activities compiled by the Mathematics Department at Frisbie Middle School in Rialto, Calif. for use at its Multicultural Math Fair. Although the activities are from the 1999-2000 Multicultural Math Fair, the Math Forum maintains the website and all the links were current at the time of this report. The website includes some tips on how to set up a Multicultural Math Fair as well as data sheets and software for some of the activities, such as the Tower of Ha

The Origins of Sex: a history of the first sexual revolution [Audio]
Speaker(s): Dr Faramerz Dabhoiwala | Nowadays we believe that consenting adults have the freedom to do what they like with their own bodies. We publicise and celebrate sex; we discuss it endlessly; we are obsessed with the sex lives of celebrities. We think it wrong that in other cultures people suffer for their sexual orientation, that women are treated as second-class citizens, or that adulterers are put to death. Yet until quite recently our own society was like this too. For most of western

All right, the C++11 Standard is done. Can we go home? Definitely not - progress waits for no one.

For all its might, C++11 is not addressing a few basic needs in template programming. For example, you'd hate to have to define a new function or indeed a whole new class wherever you need an "if" statement; yet, this is exactly what we do for template code. Also, conditional overloading using the likes of std::enable_if is syntactically bulky and semantically ham

Electricity and Gas: Market Design and Policy Issues
European gas and electricity markets have largely been liberalized. Due to the specific physical characteristics and public interest aspects of electricity and gas, and to the fact that the networks continue to be natural monopolies, these markets require careful design. In this class, it is analyzed what the market design variables are and how the ongoing process of market design depends on policy goals, starting conditions and physical, technical and institutional constraints. In addition, a n

PediNeuroLogic Exam: 3 Month Old: Normal: Primitive Reflexes - Moro
The baby no longer has a Moro reflex. Usually the Moro reflex is absent by 4 to 5 months of age. Persistence of the Moro reflex beyond this time can be seen with upper motor neuron disorders. A neuroscience tutorial focusing on those aspects of the pediatric neurological examination that are unique to the child's nervous system, with an emphasis on important neurodevelopmental milestones.
