They are also used for processes that are too vast, too complex, or too dangerous to study. Please refer to the style manuals in the area for clarifications. More advanced students can compare the potential energy graphs for neon, argon, oxygen, and water which all have different interaction potential. Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining that they must have a small core. Condensation and Evaporation Does not show the equilibrium event between the two phases.
Boiling Representation of what occurs inside the bubbles formed in water as it boils. Adjust the voltage and resistance, and see the current change according to Ohm's law. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it! Build circuits with batteries, resistors, light bulbs, and switches. Explore the charges in the sweater, balloons, and the wall as you investigate! View the light as a solid beam, or see the individual photons. Use the pendulum to find the value of g on Planet X.
The total thermal energy sometimes called the total internal energy of a system depends jointly on the temperature, the total number of atoms in the system, and the state of the material. Together, the simulations promote understanding of gas laws, states of matter, phase change, and kinetic theory. Thermal energy in a system is associated with the disordered motions of its atoms or molecules. Hang masses from springs and adjust the spring stiffness and damping. Then play a game to test your ideas! More advanced students can compare the potential energy graphs for neon, argon, oxygen, and water -- which all have different interaction potential. Observe the energy in the system in real-time, and vary the amount of friction.
See how pressure changes as you change fluids, gravity, container shapes, and volume. Transport the lab to different planets. Relate the interaction potential to the forces between molecules. Note that the interactive elements in this sim have simple description that can be accessed using a screen reader. My lower level students have also been able to complete, but required 2 full periods 110 minutes total.
Add or remove heat and watch the motion of the molecules as they change phase. More advanced students can compare the potential energy graphs for neon, argon, oxygen, and water -- which all have different interaction potential. Adjust properties of the objects to see how changing the properties affects the gravitational attraction. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Create an applied force and see how it makes objects move. View the electric field, and measure the voltage.
Plot equipotential lines and discover their relationship to the electric field. Push the pump and change the volume of matter in the closed container and watch the pressure gauge respond. . Gravitational energy is associated with the separation of mutually attracting masses. Add or remove heat and watch the motion of the molecules as they change phase. See how changing from air to water to glass changes the bending angle. Measure the period using the stopwatch or period timer.
No matter how substances within a closed system interact with one another, or how they combine or break apart, the total mass of the system remains the same. Wiggle the end of the string and make waves, or adjust the frequency and amplitude of an oscillator. Explore vector representations, and add air resistance to investigate the factors that influence drag. Equal volumes of different materials usually have different masses. This animation does not show what occurs at the surface of liquid water as it boils, the interface between the liquid phase and the gas phase.
Simulations are often useful in modeling events and processes. Topic: Particles and Interactions and the Standard Model Unit Title: Matter and Interactions This simulation can help students visualize how molecules behave in solids, liquids, and gases. Push the pump and change the volume of matter in the closed container and watch the pressure gauge respond. Play with prisms of different shapes and make rainbows. Even observe a string vibrate in slow motion. Gravitational energy is associated with the height of an object above a reference point.
The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. We cannot offer interpretations about citations as this is an automated procedure. Heat, cool and compress atoms and molecules and watch as they change between solid, liquid and gas phases. View the circuit as a schematic diagram, or switch to a lifelike view. Customize the attraction to see how changing the atomic diameter and interaction strength affects the interaction. Light energy is associated with the frequency of electromagnetic waves. Add or remove heat and watch the phase change.
Change the voltage and see charges build up on the plates. Note that the interactive elements in this sim have simple description that can be accessed using a screen reader. In solids, the atoms or molecules are closely locked in position and can only vibrate. Thermal energy is associated with the temperature of an object. Electrical potential energy is associated with the separation of mutually attracting or repelling charges. Learn about projectile motion by firing various objects.
