Today, several children gathered around one child who found and put a millipede into a bug container.  They seem to have had a meaningful discussion while they watched a millipede crawl around. When is the last time that you just sat and observed an insect, a worm, or even a spider?  Children can spend countless minutes watching bugs move.   A preschooler’s introduction to bug science should include simple facts that help him distinguish bugs and insects from other creatures, such as lizards or worms. You also can teach students that while all bugs are insects, not all insects are bugs. We expose preschoolers to the science of bugs through fun activities using real bugs, books, videos and art supplies. But the most meaningful learning takes place naturally and through hands-on experiences.
