Hello, science teachers and students!
Here are a selection of apps I've designed for my teaching. Some of them based on simulations that I used to love but went offline years ago. Many of them I designed specifically for the way I teach topics based on the Ontario science curriculum. You can use them as demonstrations with a projector and/or interactive whiteboard. Many of them work well for inquiry activities so students can use them on their own laptops or in the school computer labs.
They are downloadable .jar files and you will need to install the Java Development Kit before you can run them. Instructions to do that, and to run them on your computer, are HERE.
If you are a student or teacher and have found them useful, please email me on the contact page, introduce yourself, and let me know which simulations you found most useful or how you used them. I would love to hear from you.
Check the sims (9/10 science) link at the top of the page for more.
Create square, triangle, circular or custom drawn waves to interfere with each other and reflect off of fixed or free ends. This simulation also shows the interference of sinusoid waves, transmission/reflection into denser or less dense media, and standing waves.
Simulates gravitational fields in many different situations, including: binary star systems, the Earth/Moon/ISS/Geosynchronous satellite, comets and Kepler’s second law of motion, the Solar System (including geocentric models and epicycles), a galaxy system of 500 stars, and a cloud of gas condensing under its own gravity to form a star and orbiting bodies.
An introductory visual representation of transverse and longitudinal waves, with adjustable amplitude, wavelength and frequency.
Simulates the expected and actual results from the Michelson-Morley experiment as the user rotates the table with respect to the aether wind.
Simulates the results of the quantum double slit experiment when the slits are observed or unobserved. Users can fire individual electrons or streams.
Users can perform any force lab involving friction, an inclined plane and a pulley. Weights can be added to the cart or pulley. This simulation also generates a table of values, a position-time graph and a velocity-time graph. A line-of-best-fit can be drawn on the velocity-time graph to calculate the acceleration.
Users can perform a lab to calculate the spring constant for a random spring, by graphing points and drawing a line of best fit. This simulation also shows harmonic motion with different levels of damping, as well as the energy transformations that take place for a vertically hanging mass on a spring.
Simulates and draws vector-diagrams for a boat crossing a river with a current. The boat can be pointed directly across and pushed downstream, or aimed into the current to end up directly across.
Explore magnetic fields caused by bar magnets, straight wires and solenoids. This simulation also shows the motor effect, the generator effect (induction), as well as the magnetization of ferromagnetic materials by aligning the domains.
Simulates thin film interference for adjustable wavelengths/colours of light and adjustable indeces of refraction of the media. This simulation also shows the interference pattern caused by soap rings and Newton’s rings with monochromatic or white light.
What happens when you jump or throw a ball in a rotating space station? This simulation shows you that, while simulating scale radii and rotation speeds of space stations to give different sensations of gravity.
This simulation allows users to perform different conservation of momentum labs with elastic or inelastic collisions. It also has a ballistics mode, an explosion mode, and a built-in billiards game simulator.
Simulates a DC motor and AC generator. Users can adjust the voltage / rotation speed.
A simple visual of the Cavendish experiment with values that can be used to calculate G
This simulation shows the first six harmonics of standing waves in strings and open/closed air columns. Harmonics can also be added together.
This app shows the circular paths formed by charges moving in magnetic fields. The user can fire spheres of different masses and charges with different speeds into a magnetic field and a capacitor (or both) and measure the radii. This app also simulates the separation of C12 and C14 isotopes, as well as velocity selectors.
