Chunking is learning information in categories, rather than trying to memorize a myriad of small details. The human brain has about 7 slots for information in the short-term memory, so you want to put more than a single fact in each slot. Try some different organizational schemes for chunking to see what works best for you. Here's an example:
Category: Photosynthesis
- Purpose of the process
- Organism or cells involved in the process
- Molecules involved in the process
- Steps of photosynthesis
- How photosynthesis can be inhibited or accelerated
- Tools/methods used to measure/test photosynthesis
- Similarities/differences from other mechanisms you've already learned
George A. Miller first discussed the concept of chunking in his 1956 article, "The Magical Number Seven, Plus or Minus Two."
