High School Science Vocabulary (Free)
Many high school students struggle with the depth and breadth of high school science courses. One way to relieve these stresses and learn to understand even the most intricate science concepts is by mastering the science vocabulary that expresses them. A basic understanding of each word’s definition will give students confidence to use these words and inquire about their linkages and applications.

Supercharged Science (Free-$$)
The science curriculum you’ll find here is self-guiding and very hands-on, so you’re kids won’t be reading boring lessons from a book – they’ll be doing real science, like real scientists do in the lab. They will learn more science AND enjoy it more in 2 months that they will from a typical year of “traditional” science education. The author and teacher has a Bachelor’s and Master’s Degree in Mechanical Engineering with a minor in Mathematics and a specialized study in High Temperature Gas Dynamics during PhD work at Stanford. She started teaching Mechanical Engineering at Cal Poly State University at 21, volunteer teaching in local high and jr high schools, worked for NASA at 17, in addition to being a pilot. She teaches in a unique and totally fun way by having students focus on wonder, discovery, and exploration.  Classes exceed state and national standards, STEM requirements, and are engaging, fun, and totally hands-on.
