Reactants, Products and Leftovers
"Overview: Create your own sandwich and then see how many sandwiches you can make with different amounts of ingredients. Do the same with chemical reactions. See how many products you can make with different amounts of r...
Vector Addition
"Overview: Learn how to add vectors. Drag vectors onto a graph, change their length and angle, and sum them together. The magnitude, angle, and components of each vector can be displayed in several formats. Subject: Mat...
Models of the Hydrogen Atom
"Overview: How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting light at the atom. Check how the prediction of the model matches the experimental results. Su...
Energy Skate Park
"Overview: Learn about conservation of energy with a skater dude! Build tracks, ramps and jumps for the skater and view the kinetic energy, potential energy and friction as he moves. You can also take the skater to diffe...
Curve Fitting (AR)
"Overview: With your mouse, drag data points and their error bars, and watch the best-fit polynomial curve update instantly. You choose the type of fit: linear, quadratic, cubic, or quartic. The reduced chi-square statis...
Reactions & Rates (AR)
"Overview: Explore what makes a reaction happen by colliding atoms and molecules. Design experiments with different reactions, concentrations, and temperatures. When are reactions reversible? What affects the rate of a r...
Plinko Probability
"Overview: The students will play a classic game from a popular show. Through this they will see the probabilty that the ball will land each of the numbers with more accurate results coming from repeated testing. Subjec...
Build an Atom
"Overview: Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas! Subject: Chemistry Level: High School Material Type: Simulation Au...
Forces in 1 Dimension
"Overview: Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity,...
Molecules and Light
"Overview: Do you ever wonder how a greenhouse gas affects the climate, or why the ozone layer is important? Use the sim to explore how light interacts with molecules in our atmosphere. Subject: Physics Level: High Scho...
Double Wells and Covalent Bonds
"Overview: Explore tunneling splitting in double well potentials. This classic problem describes many physical systems, including covalent bonds, Josephson junctions, and two-state systems such as spin 1/2 particles and...
Concentration
"Overview: Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to co...
Moving Man
"Overview: Learn about position, velocity, and acceleration graphs. Move the little man back and forth with the mouse and plot his motion. Set the position, velocity, or acceleration and let the simulation move the man f...
Lasers
"Overview: Create a laser by pumping the chamber with a photon beam. Manage the energy states of the laser's atoms to control its output. Subject: Physics Level: High School Material Type: Simulation Author: Carl Wieman...
Area Builder 1.1.22
"Overview: This simulation gives students the opportunity to explore both area and perimeter of 2-dimensional shapes. Students can explore by creating shapes and having the sim calculate the area and perimeter. They can...
Ramp: Forces and Motion
"Overview: Explore forces and motion as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces. Graphs show forces, energy and work. Subje...
Quantum Wave Interference
"Overview: When do photons, electrons, and atoms behave like particles and when do they behave like waves? Watch waves spread out and interfere as they pass through a double slit, then get detected on a screen as tiny do...
Alpha Decay (AR)
"Overview: Watch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. See how random decay times relate to the half life. Subject: Physical Science Level: Middle School, High School, Communit...
