The primary objective of this U.S. Geological Survey Open-file Report is to improve seismic-hazard assessments in regions of Wyoming with low to moderate levels of historic seismicity. A map and pamphlet are available for download in PDF format. The map shows faults and folds with evidence of Quaternary movement including data on timing of the most recent movement, sense of movement, slip rate, and continuity of surface expression.

A survey course of discrete mathematics for non-physical science majors. Topics include systems of inequalities, linear programming, probability and probability distributions, and an introduction to descriptive statistics. The course emphasizes problem solving through the use of computer spreadsheets.

This towing lab students use a active learning activity to develop planning, problem solving and conceptual skills to clarify understanding of applied and net force. The assessment is the correct composition of a vector diagram.

This hands-on OLogy experiment uses Jell-O, fruit, nuts, and candy to demonstrate how space bends around anything that has mass. The activity begins with kid-friendly introductions to the concept of mass and Einstein's theory of bending space. The illustrated, step-by-step directions include notes about how the fruit, nuts, and candy represent stars, planets, and other objects in space. At the end, kids are encouraged to celebrate their new-found knowledge by digging into their edible space.

This activity is a 2 part lab activity where students record properties of various bars of soap, and make models of molecules as they are cooled or heated. Students develop a new experiment changing one variable.

This activity is an inquiry investigation where students manipulate a variety of objects in a variety of situations to develop an understanding of inertia.

Figuring out the acceleration of ice down a plane made of ice. Created by Sal Khan.

Identifying forces or force components acting as the centripetal force for a ball on a string moving in a horizontal circle.

A worked example finding all force vectors acting on a pendulum moving in a horizontal circle.

David explains the link between work and kinetic energy. Created by David SantoPietro.

David explains how to use a force vs. time graph to find the change in momentum and solves an example problem to find the final velocity of a spaceship. Created by David SantoPietro.

David explains the equation that represents the motion of a simple harmonic oscillator and solves an example problem. Created by David SantoPietro.

Find out why you can make music by blowing into empty bottles. Created by David SantoPietro.

This course is an overview of engineering approaches to protecting water quality with an emphasis on fundamental principals. Theory and conceptual design of systems for treating municipal wastewater and drinking water are discussed, as well as reactor theory, process kinetics, and models. Physical, chemical, and biological processes are presented, including sedimentation, filtration, biological treatment, disinfection, and sludge processing. Finally, there is discussion of engineered and natural processes for wastewater treatment.

In this activity, students use mathematics to understand tides and gravitation and how gravity works across astronomical distances, using an apparatus made from a slinky, meter stick, and a hook. A description of the mathematical relationships seen in the demonstration is included. The resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

This video introduces the concept of daylighting - the use of windows or skylights for natural lighting and temperature regulation - and how it is a building strategy that can save operating costs for homeowners and businesses.

In this activity about electricity, learners produce a spark that they can feel, see, and hear. Learners rub a Styrofoam plate with wool to give it an electric charge. Then, they use the charged Styrofoam to charge an aluminum pie pan. Essentially, learners build an electrophorus (Greek for "charge carrier"). This resource also contains instructions on how to build a large charge carrier called a "Leyden Jar" using a plastic film can.

This activity is an outdoor lab investigating Newton's Third Law with film canister cannons.

In this simple exploration, a coiled phone cord slows the motion of a wave so you can see how a single pulse travels and what happens when two traveling wave pulses meet in the middle.
