Science Buddies: Elementary STEM Activities
Science Buddies has an elementary-school collection of hands-on building and experimenting projects.
Among them are a paper roller coaster, a paper rocket and ice cream made in a bag, each with a materials list and steps. Elsewhere on the site, guides to the scientific method and engineering design show how to turn a project into a testable question by changing one feature and recording the result. The elementary filter narrows a site that also covers science fairs and careers.

Who it suits
This collection is filtered for elementary school. Projects run from simple paper builds to chemistry demonstrations, so some will sit more easily with a younger child than others.
Notes for parents
Choosing a project around materials already in the house keeps setup short.
