Pack contains questions to assess students understanding of the Arrhenius equation. There are a set of numerical calculations, together with questions requiring graphical analysis and interpretation. Given the limited resources available for this topic, there is an Excel sheet provided which can be used to generate bespoke questions by the teacher. These are correctly formulated to generate full questions and answers that can be directly given to learners. Instructions for use included within the Excel sheet.
Revision mind maps to support learners during their preparation for the year 10 externally marked May 2017 examination in Edexcel GCSE sciences.<br />
<br />
PLEASE NOTE - Topics are limited to those covered exclusively within the May 2017 assessment, across all three sciences.
Experiment to determine the sodium bicarbonate content of bottled water.<br />
<br />
This practical is a requirement within the new Pearson BTEC Level 3 specification (Unit 19 - Assignment A).<br />
<br />
This investigation consists of three parts: an initial titration to standardise hydrochloric acid; a dilution; and a final titration to determine the concentration of sodium bicarbonate in bottled water. This is an excellent investigation to assess volumetric technique over a number of experiments, giving students a real sense of ownership and application.<br />
<br />
Technician sheets are provided, alongside student worksheets with structured support for analytical calculations.
Worksheets and resources to deliver a boat design activity. Students are set the challenge to design a boat which floats and carries passengers. They must fully budget for materials. Each boat can be tested in turn and points awarded to identify a winner. This can be delivered as a standalone activity, or linked with the theory of density.
A booklet of experiments that students can complete under supervision at home. Booklet is designed to engage learners outside of the classroom. Contains six experiments across all three sciences, including the extraction of DNA, measuring the speed of light, and creating a bubble bomb. All experiments involve household items and chemicals.
Worksheets and resources to deliver a bridge design activity. Students are set the challenge to design a bridge which crosses a 30 cm gap and supports a car. They must fully budget for materials. Each bridge can be tested in turn and points awarded to identify a winner. This can be delivered as a standalone activity, or linked with construction and engineering.
Table filling activity requiring students to determine the mass number, atomic number, and the number of protons, neutrons and electrons in different atoms/ions.
Dice game designed to support students whilst learning the solubility rules. Ideal for GCSE science/chemistry classes and chemistry A-level students looking to recap. Dice are used to select different, soluble ionic compounds. The learner should then determine the products and decide whether they are soluble or insoluble, based on the solubility rules. The activity is differentiated for more able learners, asking them to generate balanced chemical equations.
Simple worksheet allowing students to guide themselves through the steps of extracting DNA from kiwi fruit. This is an excellent activity with both younger and older learners. NOTE: It is now a required practical of the GCSE Edexcel science qualification. The worksheet can be printed in A3 and used as a table mat, making cleaning up much easier.
Acid-Base titration experiment to determine the unknown concentration of an acid. Basic titration suitable for KS4/KS5. Results table included. Two analysis sheets allowing for appropriate differentiation: one with limited guidance, the other with more structured support. Technician sheet included.
A collection of practical experiments, ideally suited for primary school students. These can be carried out with both small or large groups. The experiments are excellent either as stand along activities or to link with relevant curriculum areas. They are also well suited for rewards events and other engagement opportunities.<br />

Exciting experiment which can be used across all key stages. Students prepare a chocolate mixture using laboratory equipment, and food grade chemicals which are all edible and easy to source. They then perfect their pipetting technique to create chocolate spheres.<br />
<br />
This experiment can be differentiated by using Gilson pipettes and is an excellent way to train students in their correct use. The experiment can be further expanded to incorporate research tasks for the various reagents and what their role is in the spherification process.
Quick starter activity where students match reactants (acid and alkali) with their products (salt and water). Useful to review knowledge from previous lesson.
Group activity to support students in identifying common chemical hazard symbols. Each learner has a particular symbol/definition and must "think/pair/share" with other students to complete their table. Activity could also be delivered as a research task. Old and new symbols included.
