Hi there! Secondary research is like looking for toys to play with, but instead of looking for them in your toy box, you look for them in a big library filled with books and computers.
Sometimes when you want to know something, like what the weather will be like tomorrow or what a lion looks like, you can ask someone who knows or look it up in a book or the internet. That's called primary research.
But sometimes, the information you need has already been researched and published by other people, and that's called secondary research. It's like someone looked for the toys before you, found them, and put them in a special place for you to use.
For example, if you are learning about whales, you can find books or articles about whales that other people have already researched and written. You can also use data and reports that scientists have gathered about the habitats, diet, and behavior of whales.
Secondary research is useful because it saves time and money, and you can benefit from the work of others who have already done the job of collecting and analyzing information. But you need to make sure that the information you use is reliable and accurate, and that you give credit to the people who did the research.
