Build an Atom
Put your knowledge of atomic structure to the test with this challenging atom building simulation from the good guys at PhET. Atomic Structure Gridlocks
Combine atomic structure study and a love of sudoku in this tricky gridlock challenge. Ionic Bonding Interactive
This neat interactive will help you construct ionic compounds using ionic charges. Balancing Equations
Now you've seen the demo - do it yourself! Work your way up the different difficulty levels in this game to create balanced chemical equations. |
RATES OF REACTION
You will need to know:
You will need to know:
- collision theory
- effect of concentration, surface area, temperature, catalysts
- calculating the rate of a reaction
Rate of Reaction Simulation
Here's the PhET simulation to run LOTS of rate of reaction experiments in record time.

ACIDS AND BASES AND REACTIONS
You will need to know:
Acids, Bases and Metals
Have a look at this great interactive by BBC Bitesize - Acids, Bases and Metals.
You will need to know:
- pH scale
- litmus and universal indicator
- identifying oxygen, hydrogen and carbon dioxide gases
- acid + metal oxide reactions
- acid + metal hydroxide reactions
- acid + metal carbonate reactions
- uses for neutralisation, carbon dioxide formation and salt production

PhET Simulations
You guessed it. PhET's got you covered for the pH scale as well. First try diluting different substances to see what effect it has on pH. Then switch it to the micro version to see how you're actually changing the amounts of H3O+ and OH- ions.
