As of March 2015, two reliable places to find safe and educational science experiments for kids are the websites for the American Chemical Society and Scientific American. Education-focused publications, including Mentalfloss and PBS Parents, also publish science experiments online.
The American Chemical Society website features several experiments that are designed to teach chemistry principles and keep kids entertained. Experiments use supplies that appeal to kids' sense of humor or curiosity, such as slime, diapers and food coloring. The site provide videos and printed instructions, as well as an explanation of the science involved.
In the Bring Science Home section of the Scientific American website, parents can browse experiments from all branches of science, including nanotechnology, environmental engineering and ocean science. The site publishes a new activity every week, each designed for kids aged 6 to 12. Each experiment includes detailed supply lists, directions and background explanations.
Mentalfloss, an education-focused magazine, gathers a variety of fun science experiments from around the Internet. Each one is designed for parents and children to do together. PBS Parents presents science experiments in age-appropriate divisions, from preschoolers to older elementary-school children. Parents can also choose activities based on locations such as the kitchen, the park and the grocery store.
