Earthquakes happen all over the world. Where you live might determine how severe the damage might be. Watch this short video to see how different the results of an earthquake can be and why these outcomes varied.
Earthquakes can be scary and dangerous — with collapsing buildings posing one of the largest risks. Why do buildings collapse in an earthquake? How can it be prevented? Learn the physics of why it is not the sturdiest buildings, but the smartest, that will remain standing.
Learn the functions performed by the parts of a direct current (DC) electric motor by manipulating and assembling the component parts (commutator, armature, power source, and magnet). Investigate the most effective arrangement of component parts by manipulating the magnetic field strength along with...
Manipulate a simple direct current (DC) circuit to explore the relationships between current, voltage, and resistance. Your collected evidence can be saved and graphed to illustrate these relationships. A glossary is also included in the resource. (site)
Explore changes in voltage and current when modifying the main components (electrodes, electrolytes) and the conditions (concentration and temperature of electrolyte solution) in an electrochemical cell.
Learn how electrons are transferred from object to object and how the electrical charge of the object changes. Static charges are investigated with an animation of common materials and are tested with an electroscope (an instrument used for detecting the presence of static electric charge).
Explore the function and components (chemicals, electrolytes, electrodes, and terminals) of electrochemical wet cells and dry cells. Then construct a wet cell in a virtual lab. The resource also explains how cells create a potential difference and an electric current at the molecular level.
This interactive gives you a chance to explore metal at its atomic level. The tightly packed atoms give metal its special characteristics and determine how metal reacts against the stress of heat and outside forces.
Experience the engineering design process as an aerospace engineer assigned to design and test an airplane. Determine which wing and engine configuration is best suited to each mission. Find airworthy, low-cost, and fuel-efficient designs.
Help Twitch collect the parts to repair a robot by using 4 different types of simple machines: an inclined plane, lever, wheel and axle, and pulley. Select the equipment that will require the least amount of force.
