When you’re running short on microscope slides or potassium iodide, don’t forget to take this site into account. Devoted to the pursuit of science, it’s thoroughly stocked with chemicals, lab supplies, telescopes, microscopes, and water-quality instruments and meteorological equipment, so you can explore the physical world from the inside out, or vice versa. Plenty of beginner’s science kits will also help kids get on the road to genius, but please keep in mind that many of the materials found here involve some pretty heavy science, so be sure to offer parental direction, unless of course, your child is already smarter than you.
