When you carry a backpack, it can feel heavy because it has a lot of things inside. This heaviness is called a load. Just like a backpack, a truck can carry a load of boxes, and your toy train can have a load of tiny blocks.
Imagine your mind is like a big sponge. When you learn new things, you are loading your brain with information, just like how the sponge soaks up water. But if you try to load too much, the sponge can’t hold it all, and your brain might get tired!
Think of a load as the number of toys you can carry in your arms. If you carry too many, they might fall! So, a load is about how much you can hold or manage at once, whether it’s toys, thoughts, or something else.
