You are trying to train your brain to be able to remember this content, so you need to practice remembering. For example, copy and complete the Feynmann Technique template below. You could cover you choice from
Energy flow through an ecosystem
Carbon cycle
Nitrogen cycle
Do not refer to your notes except just before the green section.
You often need to take notes for ESS. There are two main situations for this:
For the weekly homework
For revision for exams
In both cases, I encourage you to read first and write second. When I make notes, I usually read the section under a sub-heading and then make notes on it from memory, before checking back if I missed something.
Read 2.3 from the revision guide below. Carefully complete the Cornell notes as you do so. Focus on ensuring you write something in all of the Cornell notes boxes.
Sometimes you aren't sure what exactly you need to know. Two sources help you identify the key learning points.
1. Mr G website has very simplified explanations.
2. Science Sauce website has guided notes PDFs.
Use the Mr G website (link below) to complete the Science Sauce PDF below (up to the end of page 4)
There is a Quizlet set available for every section of the syllabus on the Mr G website (at the bottom of each page).
The applications section of the syllabus gives you great examples of possible exam question.
Analyse quantitative models of flows of energy and matter.
Construct a quantitative model of the flows of energy or matter for given data.
Analyse the efficiency of energy transfers through a system.
Calculate the values of both GPP and NPP from given data.
Calculate the values of both GSP and NSP from given data.
Discuss human impacts on energy flows, and on the carbon and nitrogen cycles.
Here's another question that you should do and review:
