Have you ever forgotten where you kept your pencil or what you studied yesterday? This topic is popular because children often ask why the brain remembers some things but forgets others. Scientists say forgetting is actually a normal and useful part of how memory works.
Memory is the brain’s ability to store, keep and recall information. It helps us learn, recognise people and remember experiences.
What is memory?
Memory is how the brain:
-
Takes in information
-
Stores it safely
-
Brings it back when needed
Everything you learn — from riding a bicycle to spelling a word — uses memory.
How memory works
Memory works in three main steps:
-
Encoding – the brain receives information
-
Storage – the brain saves the information
-
Recall – the brain brings it back later
If any step is weak, remembering becomes harder.
Why we forget things
Forgetting can happen because:
-
The brain is overloaded with information
-
We don’t pay full attention
-
We don’t revise or practise
-
We are tired or stressed
Sometimes, the brain forgets unimportant details to make space for new learning.
Is forgetting a bad thing?
Forgetting is not always bad. It helps:
-
Clear old or unused information
-
Focus on important memories
-
Reduce confusion
Scientists say forgetting helps the brain work more efficiently.
How to improve memory
Children can strengthen memory by:
-
Getting enough sleep
-
Eating healthy food
-
Revising lessons regularly
-
Learning with pictures and stories
-
Teaching others what they learn
Games, puzzles and reading also help keep the brain active.
Memory and emotions
The brain remembers emotional events better.
That’s why happy moments, surprises or scary events are remembered more clearly.
Why kids should care
-
Good memory helps in school
-
Understanding memory reduces stress
-
Smart habits make learning easier
Teachers say learning how memory works helps children become confident and organised learners.
Fun fact
Your brain can store more information than the largest computer ever built!
In short: Memory helps us learn and grow, and forgetting is a natural part of how the brain works.
Learning takeaway: Taking care of your brain helps your memory stay strong — learning becomes easier when the mind is healthy and calm. 🧠✨
