Start with Science Book 5
Book 5 is the best fit for students in Grades 5 and up who read confidently, understand atoms, and are ready for more complex science. This level increases rigor while keeping everything coherent and explainable.
Middle grades ready
More complexity
Stronger science reasoning
Clear, coherent model

FAQ
What if my child is older but missing foundations?
If “atom” is still unclear, start with Book 1 even if the student is older.
Book 5 works best when the atomic model is already in place.
Do I need the Teacher Dashboard?
Not required, but it makes teaching dramatically easier: lesson plans, answers, labs, quizzes, rubrics, and printables in one place.
Can I switch formats later?
Yes. Many families start with the student option first, then add digital access or the teacher dashboard as needed.
