<p>Pupils need to use the equation for image size, magnification and actual size to answer this worksheet. It also consolidates standard form and adapations of specialised cells.</p>

<p>This is suitable for GCSE Biology or Combined Science Trilogy. There are 4 genetic crosses for pupils to complete at GCSE grades 4/5 or 6/7 with the mark schemes. You could print or project these for pupils to do.</p>

<p>A PowerPoint which can be used to deliver a lesson investigating how the size of a beaker placed over a tea-light affects the time the tea-light stays lit.</p> <p>Could be KS3 or KS4 with a focus on repeats and discounting anomalies</p>

<p>Suitable for GCSE Biology or Combined Science Trilogy. A 30 minute mini test and mark scheme for ‘Cell Biology’. Get the pupils to complete this for 30 minutes and then ask pupils to use the mark scheme and assess themselves.</p>

<p>The worksheet is aimed at lower to middle ability groups - measuring how much of the metre ruler passes through the hand. The PowerPoint is aimed at higher ability students - converting the distance of the metre ruler into a reaction time. The slides with results table and questions can be printed as a worksheet for students.</p>

<p>The first page is what you need to print and give to the pupils as the ‘plant’. I print them in green and get them laminated so they last longer. The second page contains the light, temperature and carbon dioxide cards. You print these and cut them out before putting the pieces into envelopes. Make sure that each set of cards is missing something (one set has very few L cards, one has very little T cards etc . . . ). Pupils pull the cards out of the envelopes at random one at a time and ‘build’ their plant. Pupils cannot grow their plant to the next level until they have completed the previous level. If a pupil pulls a card out that they already have for that level they put it back in the envelope. Ask the class: Does anyone have any problems growing the plant? Explain that they are all missing something and that the things they are lacking is the limiting factor!</p>

<p>These are BINGO games for AQA Combined Science Trilogy Revision. Print the BINGO cards for pupils (they are all the same) and pupils cross out what they think the answers are to the questions without collaboration to measure their understanding. Then go through it with them to see if or where they went wrong!</p>

<p>I use this with my form class to find out more about the pupils - invaluable to build relationships and find a ‘way in’ with more challenging individuals.</p> <p>Spelling bee useful form time activity</p>

<p>Here we have two dominoes games.</p> <p>One for KS3 Energy costs and one for AQA Combined Science Trilogy ‘Electricity’.</p> <p>Simply print the PowerPoints as handouts (two slides per page) and jumble the pieces up. Pupils then play dominoes by arranging the pieces from start to end, matching the questions and answers.</p>

<p>10 revision acrostics - Photosynthesis, Cells, Digestion, Breathing, Respiration, Acids and Alkalis, Reproduction, Organs Systems, Microbes and disease and Homeostasis. Ideal for test revision, lessons starters or literacy links.</p>
