Personal science is a way for people to do experiments and investigations about things that interest them. It involves collecting data, asking questions and researching things to find out the answers. For example, if you wanted to find out what kind of animals live near your house, you could go outside and look and count the different kinds of animals you see. Or if you wanted to learn more about a certain plant, you could water it, track how much it grows, and look up information about it online. Personal science is a fun way to learn more about the world around you.
