<p>This resource can be used to develop recall and application of the electricity equations in GCSE Physics:</p> <p>V = IR<br /> P = VI<br /> Q = It<br /> E = Pt<br /> E = QV</p> <p>The formula triangles are shown on the worksheet but can easily be removed if appropriate. The task involves students calculating all of V, I, R, E, P, t from a given set of values. It requires students to think about how they can work out a missing variable based upon what they’ve been given. The values used in the worksheet tend to be small whole numbers so this worksheet can be completed without a calculator for extra challenge.</p>

<p>This resource includes two worksheets covering the calculations topic of GCSE Chemistry</p> <p>Students are presented with a series of increasingly challenging calculation questions. After answering each question, students can check that their answer appears in a jumbled up list of answers. If their answer appears, students know that they’ve got the answer correct and can move to the next question with confidence. This independent approach frees up the teacher help the students who need it most, whilst also ensuring that the other students aren’t simply looking up answers in a mark scheme!</p>

<p>This independent revision activity carefully guides students to:</p> <ol> <li>Identify the ions present in a given mixture: water, acids, alkalis, molten salts, aqueous salts</li> <li>Predict the ions discharged at each electrode during electrolysis and the products formed</li> <li>Predict what remains after electrolysis (e.g., NaOH from NaCl electrolysis)</li> </ol> <p>Students use the “rules” to answer the questions above for 36 different electrolysis mixtures, giving extensive practice of each type of problem.</p>

<p>A spreadsheet with 40 examples (initial and final velocities, masses) of elastic and inelastic collisions. Changes in Kinetic Energy are also calculated.</p> <p>An example of how this could be used as a worksheet is also provided.</p>

<p>A series of linked questions for students to recap on key topics on GCSE Chemistry Paper 1. This task will be relevant for students of both foundation and higher tier. It will be useful for last minute revision and encourage students to recall and make links across the GCSE Chemistry topics.</p>

<p>This resource includes two worksheets covering the following topics:</p> <p>Worksheet 1 - Energy, Electricity<br /> Worksheet 2 - Forces, Waves, Magnetism</p> <p>Students are presented with a series of increasingly challenging calculation questions. After answering each question, students can check that their answer appears in a jumbled up list of answers. If their answer appears, students know that they’ve got the answer correct and can move to the next question with confidence. This independent approach frees up the teacher tohelp the students who need it most, whilst also ensuring that the other students aren’t simply looking up answers in a mark scheme!</p>

<p>This independent revision activity carefully guides students to write word equations for a range of different reactions involving metals and their compounds (oxides, hydroxides, carbonates).</p> <p>Students use examplars to complete 50 different word equations, giving extensive practice of each type of problem.</p>
