      OB3Qualitative food tests for starch, reducing sugar, protein and fat.OB5Investigate the conversion of chemical energy in food to heat energy.OB8Investigate the action of amylase on starch; identify the substrate, product and enzyme.OB11Carry out qualitative tests to compare the carbon dioxide levels of inhaled and exhaled air.OB39Investigate the variety of living things by direct observation of animals and plants in their environment;classify living organisms as plants or animals, and animals as vertebrates or invertebrates.OB44Prepare a slide from plant tissue and sketch the cells under magnification.OB49Show that starch is produced by a photo-synthesising plant.OB58Investigate the conditions necessary for germinationOB59Study a local habitat, using appropriate instruments and simple keys to show the variety and distributionof named organisms.OB65Investigate the presence of micro-organisms in air and soil.

      Chemistry: Pages 5 - 8

      OC2Separate mixtures using a variety of techniques: filtration, evaporation, distillation and paper chromatography.OC17Grow crystals using alum or copper sulphate.OC19Investigate the pH of a variety of materials using the pH scaleOC22Show that approximately one fifth of the air is oxygen;Show that there is CO


      and water vapour in air.OC24Prepare a sample of oxygen by decomposing H




      using MnO


      as a catalyst.OC27Prepare carbon dioxide and show that it does not support combustion.OC30Conduct a qualitative experiment to detect the presence of dissolved solids in water samples, and testwater for hardness (soap test).OC38Titrate HCl against NaOH, and prepare a sample of NaCl.OC46Carry out an experiment to demonstrate that oxygen and water are necessary for rusting.OC51Investigate the reaction between zinc and HCl, and test for hydrogen.

      Physics: 9 - 13

      OP2Measure the mass and volume of a variety of solids and liquids and hence determine their densities.OP6Investigate the relationship between the extension of a spring and the applied force.OP20Identify different forms of energy and carry out simple experiments to show the following energyconversions:(a) chemical to electrical to heat energy (b) electrical to magnetic to kinetic energy(c) light to electric to kinetic energy.OP23Investigate and describe the expansion of solids, liquids and gases when heated, and contraction whencooled.OP31Carry out simple experiments to show the transfer of heat energy by conduction, convection andradiation; investigate conduction and convection in water.OP34Show that light travels in straight lines.OP38Investigate the reflection of light by plane mirrors, and illustrate this using ray diagrams;demonstrate and explain the operation of a simple periscope.OP46Plot the magnetic field of a bar magnet.OP49Test electrical conduction in a variety of materials, and classify each material as a conductor or insulator.OP50Set up a simple electric circuit; use appropriate instruments to measure current, potential difference(voltage) and resistance, and establish the relationship between them.

      Any experiment could come up; there's no way of predicting because there's so many. Make sure you are able to (a) Explain the experiment (b) Draw a diagram of the equipment or set up of the experiment and (c) Answer questions based on the experiment
