Divide and conquer. That simple strategy gave the owners the advantage over labor until the dawn of the 20th century. Laborers did not all have the same goals. By favoring one group over another, the bosses could create internal dissent in any union. Unions were spread from town to town. Unity among them might make a more effective boycott or strike, but bringing diverse groups together across a large area was extremely difficult.

Students analyze the relationship between wheel radius, linear velocity and angular velocity by using LEGO(TM) MINDSTORMS(TM) NXT robots. Given various robots with different wheel sizes and fixed motor speeds, they predict which has the fastest linear velocity. Then student teams collect and graph data to analyze the relationships between wheel size and linear velocity and find the angular velocity of the robot given its motor speed. Students explore other ways to increase linear velocity by changing motor speeds, and discuss and evaluate the optimal wheel size and desired linear velocities on vehicles.

Students use the scientific method to determine the effect of control surfaces on a paper glider. They construct paper airplanes (model gliders) and test their performance to determine the base characteristics of the planes. Then they change one of the control surfaces and compare the results to their base glider in order to determine the cause and effect relationship of the control surfaces.

Cars: Engineering for Efficiency
Conditions of Use:
Read the Fine Print
Rating

Students learn how the aerodynamics and rolling resistance of a car affect its energy efficiency through designing and constructing model cars out of simple materials. As the little cars are raced down a tilted track (powered by gravity) and propelled off a ramp, students come to understand the need to maximize the energy efficiency of their cars. The most energy-efficient cars roll down the track the fastest and the most aerodynamic cars jump the farthest. Students also work with variables and plot how a car's speed changes with the track angle.

Controlling Potato Blight: Past, Present, and Future
Conditions of Use:
Read the Fine Print
Rating

Potato late blight, Phytophthora infestans, has an infamous past, yet it continues to present a challenge to modern day farmers. Historical scenarios in the LateBlight simulation help us define the impact of this disease before the interactions between this microbe and the potato were understood. Modern scenarios enable us to investigate current strategies to control this pathogen from the management of cull piles to the use of genetically engineered potatoes. A life cycle model, Potato Late Blight, provides an additional method for exploring microbial interactions. * make a profit or lose the farm as you investigate the economic consequences of using chemical control approaches to managing late blight in potatoes

Control of Feeding - Anatomy & Physiology
Rating

Different hormones, neurotransmitters and reflexes are involved in the complicated process of feeding in animals. Secretions and motility of the gastrointestinal tract are stimulated and carefully regulated by numerous factors, including environmental stimuli and the presence of food in different parts of the gastrointestinal tract from the oral cavity right through to the intestines. When a harmful substance is ingested the body acts to eliminate it in different ways to prevent the animal becoming ill, for example, through vomiting and diarrhoea. If one or more of the pathways in controlling feeding is damaged or inhibited, then problems such as obesity occurs.

Gone with the Wind - Sail Cars!
Conditions of Use:
Read the Fine Print
Rating

Students explore the use of wind power in the design, construction and testing of "sail cars," which, in this case, are little wheeled carts with masts and sails that are powered by the moving air generated from a box fan. The scientific method is reviewed and reinforced with the use of controls and variables, and the engineering design process is explored. The focus of the activity is on renewable energy, as well as the design, testing and redesign of small cars made from household materials. The activity (and an extension worksheet) includes the use of kinematic equations using distance, time traveled and speed to enforce exponents and decimals.

How Many Drops?
Conditions of Use:
Read the Fine Print
Rating

In this lesson and its associated activity, students conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. The three liquids are water, rubbing alcohol, and vegetable oil; because of their different surface tensions, more water can be piled on top of a penny than either of the other two liquids. However, this is not the main point of the activity. Instead, students are asked to come up with an explanation for their observations about the different amounts of liquids a penny can hold. In other words, they are asked to make hypotheses that explain their observations, and because middle school students are not likely to have prior knowledge of the property of surface tension, their hypotheses are not likely to include this idea. Then they are asked to come up with ways to test their hypotheses, although they do not need to actually test their hypotheses. The important points for students to realize are that 1) the tests they devise must fit their hypotheses, and 2) the hypotheses they come up with must be testable in order to be useful.

Introduction to Syntax, Fall 2003
Conditions of Use:
Remix and Share
Rating

Introduction to theories of syntax underlying work currently being done within the lexical-functional and government-binding frameworks. Organized into three interrelated parts, each focused upon a particular area of concern: phrase structure; the lexicon; and principles and parameters. Grammatical rules and processes constitute a focus of attention throughout the course that serve to reveal both modular structure of grammar and interaction of grammatical components. This course is concerned with the concepts and principles which have been of central significance in the recent development of syntactic theory, with special focus on the "Government and Binding" (GB) / "Principles and Parameters" (P&P) / "Minimalist Program" (MP) approach. It is the first of a series of two courses (24.951 is taught during the Fall and 24.952 is taught in the Spring). This course deals mostly with phrase structure, argument structure and its syntactic expression, including "A-movement". Though other issues (e.g. wh-movement, antecedent-contained deletion, extraposition) may be mentioned during the semester, the course will not systematically investigate these topics in class until 24.952. The goal of the course is to understand why certain problems have been treated in certain ways. Thus, on many occasions a variety of approaches will be discussed, and the (recent) historical development of these approaches are emphasized.

Rating

In this lesson, students discover the entire process that goes into designing a rocket for any customer. In prior lessons, students learned how rockets work, but now they learn what real-world decisions engineers have to make when designing and building a rocket. They learn about important factors such as supplies, ethics, deadlines and budgets. Also, students learn about the Engineering process, and recognize that the first design is almost never the final design. Re-Engineering is a critical step in creating a rocket.
