How do you prepare amylase solution for the GCSE enzyme activity required practical?
To prepare amylase solution for a GCSE enzyme practical, first check the approved method for the school’s exam board and the current CLEAPSS enzyme guidance. Use those instructions to confirm the amylase source, preparation and amount needed, then label and store the solution according to the department’s procedure. Check that it is suitable for the planned pH investigation and temperature control.
How do you set up the Hooke's Law required practical for GCSE physics?
A GCSE force–extension station typically needs a secure stand and clamp, suitable spring, mass hanger and slotted masses, length scale, pointer or reference marker and a stable working area. The awarding-organisation method determines the load sequence and measurements. Technicians must check apparatus condition and stability, while avoiding invented mass limits, extensions or loading instructions.
What power supply does a secondary school need for GCSE physics practicals?
A GCSE physics power supply should provide the controlled low-voltage output required by the school’s approved circuit methods, with suitable current capability, clear controls, compatible protected terminals and appropriate fault protection. No single model suits every department. Map AQA, OCR or Pearson Edexcel practicals, existing components and class demand before using CLEAPSS GL124 to compare equipment.
What food tests do secondary school students carry out and what reagents are needed?
GCSE students commonly carry out qualitative tests for reducing sugars, starch, protein and lipids. AQA specifically includes Benedict’s test, iodine test and Biuret reagent in its required practical; lipid testing depends on the qualification and approved method. Reagent identity, concentration, heating, quantities, controls and disposal must be verified against the current specification and relevant CLEAPSS Hazcards.
What microscope slides and equipment does a secondary school biology lab need?
A secondary biology laboratory needs clean blank slides, suitable cover slips, light microscopes, approved specimen tools, stains where required, dropping pipettes, lens tissue and secure slide storage. Prepared slides can extend observation but do not replace student preparation skills. Quantities, materials and stain provision should follow the curriculum, simultaneous groups, microscope compatibility and current CLEAPSS guidance.
What gloves does a secondary school science laboratory need?
A secondary school science laboratory needs gloves selected for the practicals its risk assessments identify, rather than one type for every lesson. Gloves are not routinely required for all school science work. Where they are needed, choose the material and size for the specific hazard, checking the manufacturer’s chemical compatibility and breakthrough information, fit, dexterity and any latex allergy.
What concentration of sodium thiosulphate is needed for the GCSE rates of reaction required practical?
The sodium thiosulphate concentration required for a GCSE rates of reaction practical depends on the awarding organisation’s approved method and the variable being investigated. Technicians should follow the current specification or practical handbook rather than use a general concentration, then check preparation, handling, ventilation and disposal requirements against CLEAPSS Hazcard HC097b and the school’s risk assessment.
What is the Unilab range and what Philip Harris own-brand equipment does it include?
Unilab is Philip Harris’s own-brand range of equipment for school science practicals. It focuses on physics apparatus, including products used to teach electrical circuits, forces and waves, alongside general laboratory equipment. For a school technician, the useful distinction is the equipment’s teaching purpose: check each product’s current specification, connections and replacement parts before adding it to an existing setup.
How do you maintain and operate an autoclave in a school biology laboratory?
A school autoclave is pressure equipment and must be operated only by trained, authorised people under manufacturer instructions, the employer’s arrangements and current CLEAPSS GL168 guidance. Before use, confirm whether a written scheme of examination is required, that examinations and maintenance are current, protective devices function, records are complete and the intended load and cycle are specifically approved.
What safety precautions are required when using sodium thiosulphate in a school laboratory?
The main safety precautions when using sodium thiosulphate in a school laboratory are appropriate ventilation, careful preparation, clear labelling, safe storage and suitable protective equipment. When sodium thiosulphate reacts with acid, it can release sulfur dioxide gas. Teachers and technicians must therefore follow the school’s risk assessment and confirm the correct handling, emergency and disposal procedures before use.
What is a pipette filler and why is it required for school science?
A pipette filler is a mechanical device used to draw and release liquid through a pipette without mouth pipetting. It supports controlled transfer and protects users from direct oral contact with laboratory liquids. Schools should select a filler that is compatible with the pipette type and volume, train users and follow the approved method, risk assessment and manufacturer instructions.
How do you use a Geiger–Müller tube for the radioactivity required practical?
A Geiger–Müller tube is used with a compatible counter or ratemeter to detect ionising radiation and record count data. In schools, every source-based activity must follow the local rules, employer arrangements, Radiation Protection Adviser advice and current CLEAPSS L093. Source type, activity, distance, exposure time, detector voltage, handling and storage must never be inferred from generic instructions.
