Density v.1.05
Unveil the mister of density with this tool. Density help you find the answers to some density related quetions like: Why do objects like wood float in water? Does it depend on size? You can easily create a custom object to explore the effects of
Curve Fitting v.2.01
Create polynomial curves with the help of this tool. Curve Fitting enables you to drag data points and their error bars with your mouse and watch the best-fit polynomial curve update instantly. You choose the type of fit: linear, quadratic, cubic,
Color Vision v.1.03
Color Vision is a color simulation program to help you with your work. Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam,
Collision Lab v.0.01
Investigate collisions on an air hockey table. Collision Lab can help you to set up your own experiments: vary the number of discs, masses and initial conditions. Is momentum conserved? Is kinetic energy conserved?
Circuit Construction Kit (DC Only) v.3.19
Circuit Construction Kit (DC Only) create electronic circuits. An electronics kit in your computer! Build circuits with resistors, light bulbs, batteries, and switches. Take measurements with the realistic ammeter and voltmeter.
Charges and Fields v.2.04
Charges and Fields analyze electric fields. Move point charges around on the playing field and then view the electric field, voltages, equipotential lines, and more. It's colorful, it's dynamic, it's free.Charges and Fields is an easy-to-use,
Calculus Grapher v.2.03
Create function graphs with the help of this tool. Calculus Grapher draw a graph of any function and see graphs of its derivative and integral. Don't forget to use the magnify/demagnify controls on the y-axis to adjust the scale.Non-obvious controls:
Buoyancy v.1.05
Demonstrate which objects float and which objects sink. When will objects float and when will they sink? Learn how buoyancy works with blocks. Arrows show the applied forces, and you can modify the properties of the blocks and the fluid.
Build An Atom v.1.00
Build atoms with this application. Build an atom out of protons, neutrons, and electrons, and learn about its mass, charge, structure, and nomenclature.Sample Learning Goals 1. Describe the structure of an atom 2. Connect protons to element identity
