This simulation explores the factors which determine the concentration of a solution. It illustrates the relationships between moles, litres and molarity by adjusting the amount of solute and solution volume.

The moles of solute and the volume of solution (water) can be changed using sliders to make...

Molecules and Light

This simulation can be used to explore how light interacts with molecules in our atmosphere.

Sample learning objectives include:

*Explore how light interacts with molecules in our atmosphere

*Identify that absorption of light depends on the molecule and the type of light

*Relate the...

Molecule Shapes Basics

This simulation allows students to explore molecule shapes by building molecules in 3D and seeing how the molecule's shape changes as atoms are added.

It can be used to demonstrate that:

*The molecule shape is due to repulsions between atoms.

*The bonds are not fixed in place, but can rotate...
