Chemistry & MaterialsPolymers, slime, viscoelasticity, stress relaxation and creep

Why can slime stretch slowly but snap when pulled fast?

Make the same small move at different speeds, park a material-testing carriage, and watch its force change. Explore polymer networks, relaxation, creep and real research images without inventing a breaking rule.

Chemistry & MaterialsAcids, bases and the pH scale

Why is one step on the pH scale a big change?

Compare a hundredfold difference, transfer a tiny aliquot, turn a virtual burette and uncover why a weak acid and a strong acid reach different pH values at equivalence.

Chemistry & MaterialsSolids, liquids, gases and phase changes

Where does energy go while ice melts?

Give water an energy budget. Watch its temperature and phase masses, catch a melting plateau, compare two starting states and inspect an open ice structure.

Chemistry & MaterialsAtoms and chemical elements

What makes carbon different from oxygen?

Change particle counts, pin the differences, and discover what names an element. Then prepare one-electron hydrogen states, collect possible position outcomes and match energy gaps to light.
