IB Environmental systems and societies (ESS) SL Internal Assessment Example

You clearly connect your investigation to a real environmental issue in Bangladesh, which gives the work strong purpose.

Your research question is focused, measurable, and clearly states the organism, variable, outcome, and time frame.

You could briefly justify why dry biomass after 7 days is the best indicator for answering your question.

Your inquiry would be even stronger if you explained more explicitly how the laboratory setup relates to, and differs from, field conditions in Bangladesh.

You identify a relevant existing strategy for salinity management and keep it connected to the problem in your research question.

You support the strategy with evidence and show awareness that it affects different stakeholders differently.

Your discussion of tension would be stronger if it were more clearly situated in Bangladesh rather than relying heavily on broader global examples.

You could explain more specifically how proposed supports such as subsidies or training would reduce the equity problems you identify.
