Presentation with activities on all matters that relate to accuracy of measurements. Explanations of errors, tolerance, calibration & drift, uncertainty, accuracy & precision. Included is a practical whereby students determine volume from mass and density data. Density data table included from literature. Also, for consolidation, is a crossword I’ve made on this topic. Essential learning for new sixth formers embarking on science subjects and practical work, also for higher level Year 11 science pupils.

Two presentations with interactive activities: one introduces titrations placing focus on best practice, preparation of standard solutions, calculations; a second covering examples of titrations in industry with focus on the students exploring this further. A worksheet to practice titration and dilution calculations, with solutions. Pitched to Level 3 AS / L3 BTEC Applied Science students, also Higher GCSE chemistry pupils.

A detailed presentation on forensic toxicology using well known examples from the news/media. Focus is on the value of samples and analytical chemical techniques involved such as immunoassay and GCMS. Includes calculations that the toxicologist would perform, so a clear link between STEM & forensics. Would be useful for AS/A2 chemistry students so that they might gain awareness of analytical applications to the ‘real world’. Will be useful to a teacher delivering forensic material to L3 and higher.

Presentation with consolidation questions focusing on the types and methods of chemical forensic evidence collection rather than its analysis. Useful to students studying forensic science, particularly Unit 4 within the Level 3 Forensic & Criminal Investigation BTEC.

Worksheet to practise writing 1s2 2s2 2p6 etc notation using both the periodic table and box notation.

An explanation of the process from the perspective of the forensic investigator. From fire scene to lab an overview of investigative processes and analytical sampling. Useful for science / forensic careers. Forensic science subjects, BTEC Level 3 in Applied Science, Forensic & Criminal Investigation.
