Resistance in a wire - Simulation

By Sandile MHlophe -
  Topics Resistivity Resistance Circuits Description Observe changes to the equation and wire as you play with the resistivity, length, and area sliders. Sample Learning Goals Predict how changing each variable will affect the resistance. Explain the difference between resistance and resistivity.

Vector addition - Simulation

By Sandile MHlophe -
  Topics Vectors Vector Components Vector Addition Equations Description Explore vectors in 1D or 2D, and discover how vectors add together. Specify vectors in Cartesian or polar coordinates, and see the magnitude, angle, and components of each vector. Experiment with vector equations and compare vector sums and differences. Sample Learning Goals Describe a vector in your own words Explain a method to add vectors Compare and contrast the component styles Decompose a vector into components Describe what happens to a vector when it is multiplied by a scalar Arrange vectors graphically to represent vector addition or subtraction

Tutor at the door This is how I will be teaching from now on, I how the quality will be great and sound audible. What is UniTut? UniTut is a mobile application where tutors can help high school students with school work. It's making it easier for students to access private tutors and local tutors can make revenue by creating educational videos. Thanks for watching. links: blog - https://ift.tt/qWUCh5V facebook - https://ift.tt/3hjJGMy mobile app - https://ift.tt/khcXBF0 website - https://ift.tt/mOeZ8gV

Molecular and light - Simulation

By Sandile MHlophe -
  Topics Molecules Photons Absorption Light Description Turn light source on to explore. Observe what happens in the observation window as you set up different combinations of light source and molecule. Note this simulation is the first to support our pan and zoom feature, so zoom in for a closer look, if you need to. Sample Learning Goals Explore how light interacts with molecules in our atmosphere Identify that absorption of light depends on the molecule and the type of light Relate the energy of the light to the resulting motion Identify that energy increases from microwave to ultraviolet Predict the motion of a molecule based on the type of light it absorbs Identify how the structure of a molecule affects how it interacts with light

Friction - Simulation

By Sandile MHlophe -
  Topics Friction Thermodynamics Heat Description Move the Chemistry book and observe what happens. Sample Learning Goals Describe a model for friction a molecular level. Describe matter in terms of molecular motion. The description should include: diagrams to support the description, how the temperature affects the image, what are the differences and similarities between solid, liquid and gas particle motion; how the size and speed of gas molecules relate to everyday objects.

Pendulum - Simulation

By Sandile MHlophe -
  Topics Periodic Motion Simple Harmonic Motion Conservation of Energy Period Pendulum Description Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, the strength of gravity, and the amplitude of the swing. Observe the energy in the system in real-time, and vary the amount of friction. Measure the period using the stopwatch or period timer. Use the pendulum to find the value of g on Planet X. Notice the anharmonic behavior at large amplitude. Sample Learning Goals Design experiments to determine which variables affect the period of a pendulum Quantitatively describe how the period of a pendulum depends on these variables Explain the small-angle approximation, and define what constitutes a “small” angle Determine the gravitational acceleration of Planet X Explain the conservation of mechanical energy, using kinetic energy and gravitational potential energy Describe the Energy Graph from t...

Faradays Law - Simulation

By Sandile MHlophe -
  Topics Faraday's Law Magnetic Field Magnets Description Investigate Faraday's law and how a changing magnetic flux can produce a flow of electricity! Sample Learning Goals Explain what happens when the magnet moves through the coil at different speeds and how this affects the brightness of the bulb and the magnitude & sign of the voltage. Explain the difference between moving the magnet through the coil from the right side versus the left side. Explain the difference between moving magnet through the big coil versus the smaller coil.
