I love when a small fact becomes an interest. "Mel, did you know that hummingbirds are teeny tiny and have a super long beak?" that was the launching point for us watching hummingbird videos on YouTube and discovering that there's many different kinds of hummingbirds.
Children learn the most when the subject interests them. If you have a kiddo, try this. Find something they like, then "research" together and incorporate it into their play like we did here.
