In this activity students will determine the speed of a moving vehicle using a stopwatch and meter stick. Then convert units of meters/sec to miles/hr.

Try the new "Ladybug Motion 2D" simulation for the latest updated version. Learn about position, velocity, and acceleration vectors. Move the ball with the mouse or let the simulation move the ball in four types of motion (2 types of linear, simple harmonic, circle).

This activity is a lab where students make measurements of a mass on a spring and work through appropriate calculations dealing with simple harmonic motion.

Learn about position, velocity, and acceleration graphs. Move the little man back and forth with the mouse and plot his motion. Set the position, velocity, or acceleration and let the simulation move the man for you.

Build your own system of heavenly bodies and watch the gravitational ballet. With this orbit simulator, you can set initial positions, velocities, and masses of 2, 3, or 4 bodies, and then see them orbit each other.

This is a guided inquiry investigation for students to determine the state of matter of a mystery material and to make potential real world applications/products for the mystery material.

This course focuses on the latest scientific developments and discoveries in the field of nanomechanics, the study of forces and motion on extremely tiny (10-9 m) areas of synthetic and biological materials and structures. At this level, mechanical properties are intimately related to chemistry, physics, and quantum mechanics. Most lectures will consist of a theoretical component that will then be compared to recent experimental data (case studies) in the literature. The course begins with a series of introductory lectures that describes the normal and lateral forces acting at the atomic scale. The following discussions include experimental techniques in high resolution force spectroscopy, atomistic aspects of adhesion, nanoindentation, molecular details of fracture, chemical force microscopy, elasticity of single macromolecular chains, intermolecular interactions in polymers, dynamic force spectroscopy, biomolecular bond strength measurements, and molecular motors.

Students learn about frequency and period, particularly natural frequency using springs. They learn that the natural frequency of a system depends on two things: the stiffness and mass of the system. Students see how the natural frequency of a structure plays a big role in the building surviving an earthquake or high winds.

This video is one of a series produced by the Switch Energy project. It reviews the pros and cons of natural gas as a source of energy.

This homework problem introduces students to Marcellus shale natural gas and how an unconventional reservoir rock can become an attractive hydrocarbon target. It is designed to expand students' understanding of hydrocarbon resources by introducing an unconventional natural gas play. Students explore the technological factors that make conventional source rocks attractive reservoir rocks and how this advance impacts both U.S. energy supply and the environment.

This activity is a classroom lesson on how a slinky relates to sound waves and how sound waves relate to the human ear.

Produce light by bombarding atoms with electrons. See how the characteristic spectra of different elements are produced, and configure your own element's energy states to produce light of different colors.

In this hands-on activity, students examine how the orientation of a photovoltaic (PV) panel -- relative to the position of the sun -- affects the energy-efficiency of the panel.

This video describes how Colorado has planned for and uses clean energy resources to reduce its carbon footprint.

In this lab activity, students independently test Newton's ideas on the nature of motion. Students focus on how they would design a procedure to test Newton's hypothesis and then communicate that idea to others.

Students use miniature explosives to analyze actions and reactions. An Alka-seltzer tablet is sealed in a small film canister with water which sets up a pressure explosion pushing the canister one direction and an adjacent film canister in the opposite direction. Students repeat this set up but vary the mass of the second canister by adding sand. The distances that each canister travels is measured, recorded and later analyzed and discussed.

This activity is a classroom investigation where students gather information from observing Newton's first law, develop a definition of Newton's first law and force, and apply to real life situations.

This activity is a physics lab in which students generate distance vs. time graphs for skateboarders of different masses being pulled with various values of constant force. Students develop procedures, record and graph data, and analyze the data in light of Newton's 2nd law.
