Resource
Mixing drinks

The activity uses two methods to develop metacognition. First, students are asked to solve a problem and then reflect on the thinking styles that they used. In the other method students discuss four modelled thinking styles of fictional students.
Resource
Formal charge

This activity introduces formal charge – a useful tool which otherwise might not be taught. The formal charge model treats bonds as pure covalent, in contrast to the oxidation state model which treats bonds as ionic.
Resource
Entropy and equilibrium

This activity shows the students the fundamental link between entropy and equilibrium and increases students’ understanding of scientific models. It highlights the importance of mathematical descriptions in physical chemistry.
Resource
Curly arrows and stereoselectivity

This activity develops the use of curly arrows. If you have some very able students in a group, then there is an opportunity for differentiation by giving them a chance to draw curly arrow mechanisms for whatever reactions they meet.
Resource
Covalent bonding

This activity seeks to develop an understanding of covalent bonding in terms of energetic stability rather than full shells.
Resource
A new kind of alchemy

This presents some cutting edge research for post-16 students in a context that they can appreciate. It shows the students there are still big ideas to be explored in chemistry and should promote research as a career choice.
Resource
Polymer puzzles

This activity is designed to develop the students’ higher order thinking – particularly critical thinking skills – in the context of problem solving. It should help students to recall the facts about some common polymers.
Resource
Trends in reactivity in the periodic table

This could be used to follow up some work on the periodic table where the trends in reactivity in groups 1 and 7 have been identified. It can be used as a differentiated activity for the more able students within a group.
Resource
Elemental Su Doku

This activity helps students gain a familiarity with the periodic table by getting them to continually refer to it in a problem solving activity.
Resource
Noble gases

The activity sets some critical thinking and pattern spotting tasks in the context of the noble gases. This can be used to develop skills in determining mathematical relationships between variables from graphs.
Resource
Ionic bonding

An explanation often given for ionic bonding is that atoms lose or gain electrons to achieve noble gas configurations. This activity evaluates that as a complete explanation.
Resource
Bonding models

This activity gets the students to think of the model they have been taught as a model rather than the truth.
Resource
Astounding numbers

This activity is designed to be fun and generate a wow factor for the students. It tries to convey how amazing the scale is that we use in chemistry. In question 8 the students are asked to use creative thinking and come up with some questions of their own.
Resource
Rusting: a lateral thinking problem | 11–14 years

Learners apply their knowledge of rusting in the context of shipwrecks. A lateral thinking exercise and planning an investigation will help them develop higher-order skills.
Resource
Odd one out

This activity is fairly synoptic in nature and should encourage a rapid consideration of the range of concepts met in chemistry taught to ages 11–13.
Resource
Universal indicators

This activity develops understanding of universal indicators and single indicators. The students build up their understanding by mixing two indicators. They also develop an awareness that the observed colour may be due to a mixture of colours.
Resource
Chromatography worksheet

This activity extends the students’ understanding of chromatography. It links chromatography with particle theory and develops the tools of analogy and modelling.
Resource
Boiling point

This activity is designed to help students develop their critical thinking (evaluative) skills. They are presented with a surprising measurement for the boiling point of water and several suggestions as to why it might be. The main task is to evaluate the different suggestions.
Resource
Atoms, elements, molecules, compounds and mixtures

This activity is designed to help students clarify the relationship between atoms, elements, molecules, compounds and mixtures. It also develops the skill of using Venn diagrams in organising their understanding.

Candle burning investigation: planning an experiment

Concept cartoon and example investigation to practise developing a hypothesis, planning an investigation and evaluation skills
