Many homeschoolers and quite a few elementary school teachers feel unprepared to teach science. I believe that this is in large part because they have no idea where to obtain the materials necessary to teach labs. I have dealt with two very large companies, who although their primary purpose is to supply schools, will sell to individuals. However, neither one will sell either chemicals or live bacteria and viruses. These two are: Ward Science Supplies and Carolina Biological. Don't be fooled by the name. Both sell materials to teach: biology, geology, meteorology, astronomy, chemistry, and physics from kindergarten through graduate school. A third company, Home Science Tools, sells primarily to homeschoolers. They will provide chemicals in the very small quantities that a homeschooler would wish.
Every child must have a notebook size copy of the periodic table.
Super Science Concoctions: 50 Mysterious Mixtures for Fabulous Fun by Jill Frankel Hauser
KITS/EXPERIMENTS AVAILABLE FROM HOME SCIENCE TOOLS:
Perfume Science Kit - Scientists claim that particular aromas can trigger very strong memories. With this kit you can investigate the chemistry of perfumes and our sense of smell. By the way, did you know that an area of Bulgaria known as the Rose Valley grows roses to export rose essence to France for the perfume industry?
Fizzy Foam Science - With things that fizz, foam, and bubble, investigate acids and bases, mixtures, reactions, and other chemistry concepts.
Bubbleology - Investigate surface tension, buoyancy, why bubbles are round, and other properties of water and bubbles.
Cool Blue Light Experiment Kit - Study chemiluminescence and the electron quantum leap as you create cool blue light in the dark.
Chroma-Tricks Experiment Kit - Investigate the chemistry of color as you study chromatography, acid-base reactions, oxidation reactions, and dyes.
Goofy Glowing Gel Kit - Create a "silly putty" like gel, slimy ooze, and Eco-foam fizzle while learning about polymers, phosphorescence, and cross-linking gels.
Patriotic Colors Chemistry Kit - Study acid-base reactions, precipitates, and pH with a series of color changing experiments.
Rubber Flubber Experiment Kit - Investigate the properties of latex rubber and study the chemistry behind this amazing natural substance. Make rubber balls, foam rubber, waterproof cloth, erasers, and more.
