Instructional Strategies for Mental Math
These strategies support active student participation in math lessons and allow teachers to assess the developing proficiency levels of all students in the class by walking around to monitor student responses. These strategies are especially effective during the Mental Math part of an Everyday Mathematics lesson.

Spectroscopic Simulator
This applet covers an aspect of the Physical Chemistry II course that students often find confusing. Although it is based on relatively simple mathematics, a complete understanding of the phenomenon requires assimilating the following concepts: The energy levels of a diatomic molecule are given by the formula: E(v,J) = hv (v + ½) + BJ (J + 1); v = 0..infinity, J=0..infinity. A molecule absorbs light at frequencies that correspond to difference between energy levels. In this case, we are interes

SIMply Prairie: Prairie Advocates
In this multidisciplinary, inquiry-based project students prepare a plan and give a persuasive oral presentation to create a reconstructed prairie based on research. Teachers can use this unit with their students to justify enlarging or keeping an existing prairie. This project can serve as the organizing structure for prairie study where materials from units such as The Prairie – Our Heartland become research materials. It can be used in conjunction with the unit which is taught best in the f

Engineering Statics
Statics is a sophomore level engineering course, offered in all mechanical and civil engineering programs. Statics forms the essential pre-requisite to a number of follow-on courses, such as dynamics and mechanics of materials, and lays the foundation for design of mechanical systems. In most institutions, Statics is taught in a traditional way with an emphasis on the mathematical operations that are useful in its implementation, but without enough emphasis on modeling the interactions between r

Relative Humidity Protocol
The purpose of this activity is to measure relative humidity using both a sling psychrometer and a digital hygrometer. Intended outcomes are that students learn to quantify humidity and that there is a limit to the amount of water vapor that the air can hold. Students gain insight into why rain drops and snow flakes form and why there is precipitation. Supporting background materials for both student and teacher are included.

Optional Soil Moisture Sensor Protocol
The purpose of this resource is to measure the water content of soil based on the electrical resistance of soil moisture sensors. Students install soil moisture sensors in holes that are 10 cm, 30 cm, 60 cm, and 90 cm deep. They take daily readings of soil moisture data by connecting a meter to the sensors and using a calibration curve to determine the soil water content at each depth.

Soil Temperature Protocol
The purpose of this resource is to measure near-surface soil temperatures. Students measure soil temperatures at 5 cm and 10 cm depths using a soil thermometer. Students will be able to perform a soil thermometer calibration, carry out soil temperature measurements accurately and precisely and record and report soil temperature data. Students will be able to relate soil temperature measurements to the physical and chemical properties of soil.

RIAlity
The package was written in 1996. Radio immuno assay (RIA) is a technique for measuring concentrations of antigens. Although better techniques have subsequently been developed from it, understanding RIA forms the basis for understanding these derivatives. RIA belongs to the family of competition assays which are widely used in science, medicine and related industries to measure the concentrations of biologically active molecules. This package introduces the concepts of RIA and will be useful to a

Pendulum Lab
Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, and the amplitude of the swing. It's easy to measure the period using the photogate timer. You can vary friction and the strength of gravity. Use the pendulum to find the value of g on planet X. Notice the anharmonic behavior at large amplitude.
