During a study of plants, we made some predictions about how we think plants grow.
We graphed our predictions on chart paper. Later on, we discovered more about these plants through books we read or through observation whenever possible. I didn’t point out the facts to the children, but allowed them to discover it on their own. It is inevitable that the children will pick up on the facts by noticing pictures in a book, or watching something grow, or noticing the plant sitting in a field as they drive by.
It’s also very important to make sure children understand that no prediction is wrong. A prediction is simply a guess when you don’t know for sure.
