Gravitas Publications, Inc. is dedicated to bringing you the best science curriculum for students of all ages. Currently we offer chemistry, biology, and physics textbooks and workbooks for elementary and mid-school students. In the future we will have a complete K-12 science curricula.Our textbooks are easy to read and fun to use. Students explore real science using hands-on activities designed not only to teach the scientific method but also to help develop critical thinking tools necessary for success in every area of study.RS4K is unique in its "teacher-friendliness." All three levels of the curriculum cover the same topics in the same order, making it easy to teach students with various learning abilities---perfect for the home schooling family. For example, a kindergartner, a 5th-grader and a 9th-grader would all be studying atoms in Chapter 1 in their Chemistry class; the content is progressively more in depth, but the labs are similar. Using Real Science-4-Kids your student will not only learn the elements of science, but will also discover just how fun science can be!
