GoReact can be used to explore the periodic table of elements and associate elements with practical, relatable objects they are used to make. Just click on any element.
Then, there is a Featured Reactions tab- this gives directions to assemble elements in different categories, e.g. health and beauty aids. It's a great interactive website to build categories, comprehension of direction, narrative about experience of products, and describing by function.
This website is a good pairing with the fun book 11 Experiments that Failed and maybe some simple experiments using household items.
