" Topics include productivity effects of health, private and social returns to education, education quality, education policy and market equilibrium, gender discrimination, public finance, decision making within families, firms and contracts, technology, labor and migration, land, and the markets for credit and savings."

Role of the engineer as patent expert and as technical witness in court and patent interference and related proceedings. Rights and obligations of engineers in connection with educational institutions, government, and large and small businesses. Various manners of transplanting inventions into business operations, including development of New England and other US electronics and biotech industries and their different types of institutions. American systems of incentive to creativity apart from the patent laws in the atomic energy and space fields. For graduate students only; others see 6.901.

This task supports students in correctly writing numbers. Because students have to trace the number, instead of coloring in a bubble with the number in it or circling the correct number, they gain handwriting practice as well as counting and addition practice.

In this interactive demonstration students will make observations of diffusion of a semi permeable membrane and be able to compare these observations to the functions of a cell membrane.

This lab activity is a paper fossil dig where students discover skeletal characteristics of humans, primates and hominids and are asked to make a short oral presentation to the class.

Spreadsheets Across the Curriculum module. Students analyze a given data set to understand the "Digital Divide" by means of percentages and the Subtotal tool in Excel.

This task helps students understand the relationship between digit placement and the value of a number.

This task gives students the opportunity to verify that a dilation takes a line that does not pass through the center to a line parallel to the original line, and to verify that a dilation of a line segment (whether it passes through the center or not) is longer or shorter by the scale factor.

This task requires students to think of dimes and pennies as fractions of dollars.

This task does not actually require that the student solve the system but that they recognize the pairs of linear equations in two variables that would be used to solve the system. This is an important step in the process of solving systems.

The purpose of this task is to illustrate through an absurd example the fact that in real life quantities are reported to a certain level of accuracy, and it does not make sense to treat them as having greater accuracy.

In this short lab, students observe the movement of an air bubble in a small level, attached to a toy truck, as it is moved from a stop, to a steady speed and back to a stop. This gives a visual to the concepts positive acceleration, zero acceleration and negative acceleration.

Spreadsheets Across the Curriculum module. Students use spreadsheets to help find the difference in percentages of salaries between dirty and clean jobs.

In this activity, students investigate different methods (aeration and filtering) for removing pollutants from water. They will design and build their own water filters.

This purpose of this task is to help students see two different ways to look at percentages both as a decrease and an increase of an original amount. In addition, students have to turn a verbal description of several operations into mathematical symbols.

With a simple demonstration activity, students are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Then, in the Associated Activity (Sliding and Stuttering), they work in teams to use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on. By modifying the bottom surface of the cup, students can 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 this unit, students make regular journal entries about a plant/animal/insect community in the natural area around our school and use this to create a Non-fiction Class Book. They also interview family/resources to discover, record and present stories about human relationships with nature from their culture(s).

This activity is an outside the classroom teaching with data experiment. It allows students to collect and analyze data in ordet to create a distance versus time graph and calculate average velocity from the graph.

This is an investigation where students observe what happens to land after it is mined. Students will create a hypothesis, observe their model, conclude what happens to land after it is mined, and discover the role humans play in land conservation.

This lab activity shows students the Law of Conservation of Matter and intermolecular forces by having them dissolve packing peanuts in acetone.
