See the Wizdom site for more information on the research collaboration cloud environment. Since access to school laboratories worldwide has been severely restricted or has been completely unavailable for long periods during the past year this has all changed. What I realised after I had written it up for publication in Foundations of Chemistry was that effectively I had completed an individual scientific investigation using secondary data. You could then work out the percentage yield of the experiment by comparing your experimental yield to the theoretical yield. What I then did was to spend about an hour rewriting my article to addressspecifically all the IB assessment criteria without adding or changing any of the actual chemistry. All this secondary data is easily accessible to students on the Internet and the investigation could have been undertaken by a student for their IA. With the cancellation of the May 2020 exams instead of the IA component counting for only 20% of the final mark it effectively became the main basis upon which grades were awarded. Search for content by subject in the Search field. You could even look at both the bond enthalpy and length to see how they change with each other.
