Interactive Demo
Big Idea 2: Coulombic Playground
Big Idea 2: Coulombic Playground is a free, interactive learning demo from the AP Chemistry course on Lykke. It helps you build intuition for Big Idea 1: Scale, Proportion, and Quantity, Big Idea 2: Structure and Properties, Big Idea 3: Transformations, Big Idea 4: Energy. Play with it directly in your browser — it features 3 buttons, direct drag interaction and a live visual canvas. This demo lives in the “Course Framework and Big Ideas” section of the course.

How to use this demo
- Click and drag directly on the canvas to manipulate the scene.
- Use the “NaCl (+1/-1)”, “MgO (+2/-2)”, “AlN (+3/-3)” buttons to trigger actions or reset the demo.
- Experiment freely — there's nothing to break, and every change is reversible.

Frequently asked questions
What does the Big Idea 2: Coulombic Playground demo do?
This section introduces the foundational framework of AP Chemistry, focusing on the four Big Ideas and six Science Practices that guide the curriculum. It outlines how the course balances theoretical knowledge with labo… Big Idea 2: Coulombic Playground turns that idea into something you can manipulate directly and watch respond.
What AP Chemistry concept does Big Idea 2: Coulombic Playground teach?
This section introduces the foundational framework of AP Chemistry, focusing on the four Big Ideas and six Science Practices that guide the curriculum. It outlines how the course balances theoretical knowledge with labo… It focuses on Big Idea 1: Scale, Proportion, and Quantity, Big Idea 2: Structure and Properties, Big Idea 3: Transformations, Big Idea 4: Energy, Science Practices: Models and Representations, Science Practices: Mathematical Routines from the “Course Framework and Big Ideas” section.
What can I control in Big Idea 2: Coulombic Playground?
You can drag elements directly on the canvas; the “NaCl (+1/-1)”, “MgO (+2/-2)”, “AlN (+3/-3)” buttons run actions or reset the demo. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.
How does Big Idea 2: Coulombic Playground fit into the AP Chemistry course?
AP Chemistry is a college-level course designed to provide students with a foundation in chemical principles through inquiry-based investigations and nine core units of study. The curriculum emphasizes four 'Big Ideas'… This demo is the interactive piece for the “Course Framework and Big Ideas” section.

What will I understand better after using Big Idea 2: Coulombic Playground?
You'll build intuition for Big Idea 1: Scale, Proportion, and Quantity, Big Idea 2: Structure and Properties, Big Idea 3: Transformations, Big Idea 4: Energy, Science Practices: Models and Representations, Science Practices: Mathematical Routines — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on AP Chemistry alone.
