Mnemonics use patterns, rhymes, and associations to make information stick. They move information from working memory to long-term memory faster.
Types of Mnemonics
Acronyms
Use the first letter of each item to make a word:
- PEMDAS = Parentheses, Exponents, Multiplication/Division, Addition/Subtraction (order of operations)
- HOMES = Huron, Ontario, Michigan, Erie, Superior (Great Lakes)
- FANBOYS = For, And, Nor, But, Or, Yet, So (coordinating conjunctions)
Acrostics
Create a sentence where each word starts with the target letter:
- "My Very Educated Mother Just Served Us Noodles" = Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune (planets)
- "Please Excuse My Dear Aunt Sally" = PEMDAS (order of operations)
- "King Philip Came Over For Good Soup" = Kingdom, Phylum, Class, Order, Family, Genus, Species (taxonomy)
Rhymes and Rhythms
Patterns stick in memory:
- "In 1492, Columbus sailed the ocean blue"
- "I before E except after C"
- "Thirty days has September, April, June, and November..."
Associations and Images
Link new information to something you already know or create a mental image:
- To remember that mitochondria is the "powerhouse of the cell," imagine a tiny power plant inside the cell
- To remember photosynthesis = photo (light) + synthesis (making), visualize the plant absorbing sunlight
- To remember osmosis, think of "ooze"—water oozing through a membrane
The Method of Loci (Memory Palace)
Mentally place items you want to remember in familiar locations:
- Think of a place you know well (your house, a route to school)
- Mentally place each item to remember in a different location
- Walk through the space mentally to recall the items in order
Example: To remember five steps of the scientific method, place each step in a different room of your house: hypothesis on the porch, experiment in the kitchen, observation in the bedroom, analysis in the bathroom, conclusion in the living room. Walk through mentally to recall them in order.

When Mnemonics Work Best
- Lists or sequences that need to be in order
- Vocabulary with tricky spellings
- Information that doesn't have a natural logical structure
- Facts you need to know for tests
Tip: The more personal or silly your mnemonic, the better it sticks. If you create it yourself, you'll remember it longer than if someone gives it to you.
