A range of concrete activites for students to explore the relationship between the size of particles or parts and the total surface area. Concept is important in explaining the function of alveoli in the lungs, villi in the intestine, particle size in reaction rate and catalysis. The concept can be explored at differentiated levels from the basic idea to deriving a quantitative relationship, depending on age, ability and context. Additional activities are included to demonstrate the functionality of moisture and thinness of the walls in the alveoli.

Summary worksheets on the keywords describing change of state and the properties of and particle descriptions of solids, liquids and gases. The States of Matter worksheets are for different abilities and the keyword fill may be used as a preparatory sheet for students to find the keywords, or simply as an annotation sheet used in conjunction with the presentation. The wordbank cards have the meanings as well as the words and these or the flashcards may be used in conjunction with the keyword fill sheet for students to place the words before writing them down. The flashcards can be used in class for peer learning and checked with a quick quiz. Although intended for lower ability students, the longer "States of Matter cut and stick" worksheet can be useful in general on a Friday afternoon. "States of Matter - match" is intended for middle ability students and "States of matter" for higher ability.

A differentiated, challenging game to help A level students get to grips with the rules of naming organic compounds.

Video tutorial showing how to tackle calculations on equilibria in A level Chemistry. The common mistake of students not using equilibrium concentrations is pointed out and a strategy to help with that problem. Make available to students to help with homework and revision.

Differentiated, multiple choice lesson to introduce the effect of temperature on the rate of reaction. Alternative activities can be used in subsequent lessons. Allows the focus to be on Reaction Rates or How Science Works, with options to tie activites to the AQA ISA framework for GCSE Chemistry.

Introductory less on to crude oil. Differentiated starter to introduce the connection between the size of a hydrocarbon and its boiling point and Fractional Distillation of crude oil

Game to reinforce the -ide/-ate endings in naming ionic compounds. to differentiate between compounds containing oxygen and those not containing oxygen from the name of the compounds.

Game to become familiar with and to differentiate between metal and nonmetal elements. Can help reinforce the -ium ending to identify metals.

Plenary, starter or revision game to differentiate between ionic and covalent substances from their names. Makes the connection beween the presence or absence of metals and the type of bonding.

A plenary, starter or revision game to reinforce the difference between categoric and continuous variables, with examples of both types.

Worksheet with diagrams for students to describe and explain the brown gas diffusion experiment. Its worth printing this one out in colour - that usually goes down well.

The worksheets are to summarise the main properties and trends in properties of the elements in groups 1, 7 & 8. The text boxes activity sheets that go with them can be used for lower ability students as a cut and stick exercise, or a tick list to complete the worksheet.

Cut and stick activity. Match two labels to each chemical formula to name the compound represented by the formula. Students may experience a little conflict with some of the names but should be able to figure out the -ate and -ide rule from the examples given.

The worksheets are to summarise the main properties and trends in properties of the elements in groups 1, 7 & 8. The text boxes activity sheets that go with them can be used for lower ability students as a cut and stick exercise, or a tick list to complete the worksheet.

Starter slide. Sodium, sodium chloride and carbon dioxide. which is the odd one out? Several answers possible for different reasions. Students should explain why they have chosen a particular answer.

The text is used with both levels of the worksheet. Both worksheets are gradated, but aimed at different abilty levels, the LAPS sheet for lower ability students.

The power point image sheet and the pollution boxes go together. This is a cut and stick activity to distinguish between acid rain and the greenhouse effect. The pollution 1 powerpoint is to show where the text boxes should go on the diagram , before they are stuck down.

Spagetti junction matching activity. Indicate which acid and other reactant need to be put together to make the salt named in the middle. Quick starter for KS4 or quick plenary/extension for KS3 students.

The powerpoint and the tutorial together move students from simple energy level diagrams through to quantitative calculations of enthalpy of a reaction using bond energies. Molymods are needed to follow throught the activity on the slides and a bunsen burner burning is intended to be the reaction they see and write the equation for at the beginning of the starter.
