Supply and demand
Shift demand and predict the new price.
Balance the beam
Slide the weight until both sides match.
Try it
Takes about 1 minute.
The problem
Students can apply the formula for moments but can't picture what it means.
Who it's for
First-year engineering and physics
Before and after
See how we make a difference
Before
As it usually is
- A formula and a labeled diagram.
- Practice questions with numbers only.
After
Redesigned
- Change 1: Students slide a weight along the beam.
- Change 2: The sums for each side update as they move.
- Change 3: The beam tips until it balances.
- Reason for change 1: The formula sits next to the beam, so the math and the physical result are linked.
- Reason for change 2: Overshooting shows what happens, not just what's wrong.
- Reason for change 3: Students reach the answer by testing, then see why it works.
How we'd build this for you
The formula next to the thing it describes
This activity is one example of a pattern that works in almost any subject. Here's how the same idea could look in yours.
- ChemistryBalance an equation and watch the atoms on each side match.
- AccountingPost journal entries and watch the balance sheet balance.
- PhysicsChange a circuit's resistance and watch the current update.
- ArchitectureMove columns and see where a floor starts to sag.
- NutritionSwap foods and watch a day's nutrients add up.
We build it with your subject experts and your own examples, in your learning platform. Every piece works on phones, by keyboard and with screen readers.
