Scientific investigations: Reporting

Students will use a checklist to critically assess a report of a scientific investigation, and then summarise their findings. The checklist itemises all the important information that should be included in a scientific report and the scientific processes that should have been employed in the investigation.

Scientific investigations: Getting started

This resource supports students in carrying out independent investigations.  It helps them to choose, plan, carry out and write up an in-depth scientific investigation.

Metals

This resource consists of a self-study sheet and suggested practical activity.  Students will:

  • Use fully annotated diagrams to describe the structures of more than two metals and relate their structures to physical properties 
  • Carry out tests on samples of metals they have work-hardened,...

Extracting and purifying metals OCR Unit 12

This worksheet looks at electrolysis, its use in the extraction of sodium and aluminum and in the purification of copper. Having completed it, students are then asked to set up a simple electrolytic cell to obtain pure copper and calculate and measure the amount of product deposited at an electrode during...

Dyes: Industrial scale up

This is a worksheet which looks at various factors which effect the scaling up of laboratory processes to industrial scale in the commercial manufacture of dyes.  Students look at

  • costs of the raw materials for each dye 
  • the percentage yield 
  • size of reaction vessels  
  • energy...

Waste disposal, recycling and land reclamation

 Students are asked to research some of the activities of the local authorities in Somerset and relate them to national issues associated with waste disposal, environmental damage, recycling and conservation.   The activity is intended to be undertaken in small groups which then report back to each other for a...

Estimating environmental damage in freshwater

Students compare the water quality at different points in a stream or river using the standard procedure for finding the Trent Biotic Index score for samples of freshwater invertebrates.  The test was developed by the Trent River authority to detect water pollution. It allows comparisons of water quality to be made...

Distribution and abundance of species

This is a modelling activity where students use sampling techniques to determine the distribution and abundance of organisms in a simulated habitat. Students will simulate the mark–release–recapture technique (Lincoln Index) for estimating population sizes of mobile species. 

Curriculum links include: ...

Using blood pressure monitors

These activities provide the standard procedures for methods which may be employed to measure blood pressure at the beginning and end of a fitness programme. Methods are provided for automatic digital devices, for using a manually inflated cuff and stethoscope and for ambulatory blood pressure monitoring. 

Researching and planning chemical assays

This A2 level Applied Science resource guides students to research, select and use quantitative chemical analysis techniques to assay the active ingredient of common medicines. There are suggested methods to select from, questions and guided steps for calculations involved. The resource also contains student sheets...
