This simulation allows students to:

• Demonstrate an understanding of acid and base strength, given acids or bases at the same concentration, by:

1. Relating the strength of an acid or base to the extent to which it dissociates in water
2. Identifying all...

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to develop ideas relating to the characteristic reactions of acids.

With this simulation students can explore the conservation of mass and balance chemical equations. Sample learning objectives include: *Balance a chemical equation. *Recognize that the number of atoms of each element is conserved in a chemical reaction. Describe the difference between coefficients and subscripts in...

This simulation explores the Beer's Lambert Law. It allows you to make colourful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer.

Curriculum links include:

• Beer's law
• Solutions
• Concentration
• Molarity...

This simulation allows you to build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Students can then play a game to test their ideas.

Curriculum links include:

• Atoms
• Atomic Structure
• Isotope Symbols
• Atomic Nuclei...

These downloadable videos are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to introduce ideas of the energy changes which accompany changes of state.

Let battle commence! An interactive activity from the Association for Science Education (ASE), where students use video clips of displacement reactions together with animations to investigate the Reactivity Series for metals.
