The Basic Laboratory Equipment Kit includes the essential specialty labware you need to perform a wide variety of experiments in chemistry and the other sciences. It's an excellent choice for home schoolers on a tight budget or DIY science enthusiasts who are just getting started putting together a home lab.
|
This kit provides the equipment and reagents you need to perform reliable multi-step laboratory tests for detecting lead content in paints. The sulfide test, a sensitive preliminary screening test, quickly identifies paint samples that may contain lead.

The MAKE Junior Microscope Set is the perfect gift for kids age 7 through 14 who want to learn more about science and the world around them. Don't mistake this set for one of those cheap toy microscope sets you find at the mall. Kids can do real science with this set, everything from their first close-up examinations of leaf structures, insects, pond life, fibers, and other tiny items to preparing whole mount slides, section slides, and smear slides, to growing and observing their own microorganism cultures, to putting together killer science fair projects. And, although this set is best suited for elementary and junior high/middle school students, in a pinch it can serve all the way through high school.

We put this set together especially for kids in middle school through high school (age 11 - 18) who want to learn more about science and explore the microscopic world around them. This set is an excellent choice for home school students and public school students who need more “microscope time” than they get on shared equipment during school hours. It's also an excellent choice for parents who want to buy one microscope that can be used from elementary school all the way through introductory high school biology courses. (For students who will take advanced high school biology courses that require a 1000X microscope, we recommend our Advanced Microscope Set.) Yeah, this set gives your kids a big advantage against the other kids in their science classes. But they're your kids.
