Interactive Concepts

Math

These visualizers cover the graphs students meet from algebra through precalculus. Instead of memorizing that "b moves the line up", learners drag the parameter itself and watch the graph respond — the fastest way to connect an equation to its shape. Each one displays exact intercepts, vertices, and solution points as the parameters move.

Unit CircleDrag the angle to read sine, cosine, and tangent, with a full common-angle chart.

Slope-Intercept FormDrag m and b to reshape the line y = mx + b and read its intercepts.

Quadratic FunctionDrag a, b, and c to reshape a parabola and mark its vertex, roots, and discriminant.

Exponential FunctionDrag a and the base b to switch between exponential growth and decay.

Systems of EquationsDrag two lines to find where they intersect — one, none, or infinitely many solutions.

Physics

Motion is hard to reason about from a frozen textbook figure. These simulations run the actual physics: set the launch angle or spring stiffness, press play, and read the resulting trajectory, period, or velocity curves in real time. Pause anywhere to take a reading, then export the frame for a worksheet problem.

Projectile MotionDrag the launch angle and speed to reshape the trajectory, range, and maximum height.

Simple Harmonic MotionDrag the amplitude and period to reshape the sine wave and read the frequency.

Chemistry

Reactions happen at a scale nobody can see, which is why particle-level animations beat static equations for first-time learners. These visualizers show molecules breaking and forming bonds as the equation balances, with atom counts tracked live on both sides — useful for everything from GCSE combustion to A-level elimination mechanisms.

Electrolysis of WaterWatch an electric current split water into hydrogen and oxygen gas in 3D.

Dehydration of Alcohols

Dehydration of AlcoholsWatch ethanol dehydrate into ethene and water through an acid-catalyzed elimination.

Combustion ReactionWatch methane burn — CH₄ + 2O₂ → CO₂ + 2H₂O — as bonds break and re-form.

Balancing Chemical EquationsAdjust coefficients and watch the atom counts on each side balance out.

Each visualizer is built for three moments in a lesson. Project it during direct instruction and drag the parameters live while the class predicts what happens next. Hand students the link for guided exploration — every control is labeled, so a short worksheet ("set a = -2, what happened to the roots?") is enough structure. Then export stills or short animations for your own slides, quizzes, and revision handouts.

Exports come out as PNG images, looping GIFs, or MP4 clips sized for slides. The free export carries a small watermark; a watermark-free export costs one credit. Nothing here requires an account to explore.

Need a labeled static figure instead — a cell diagram, a food web, a flowchart? That is what the AI diagram generators are for: describe the figure in a sentence and get a labeled diagram you can edit and export. Concepts teach behavior; generators produce figures.
