This was our first year using Apologia High School Sciences. Our daughter used this text for 8th grade and LOVED it!!! The made the concepts easy to understand and there were lots of hands-on experiments which gave her more insight into how the processes worked.
Different style learners benefit from different approaches. For my auditory learners, we also use the audio cd-rom after they've read the textbook. *Sonlight Curriculum has a wonderful lesson plan for each of the Jr/Sr High sciences with Apologia, to make your planning easier. Another tip: Quizlet & StudyStack websites help you make or play flash card games & practice quizzes throughout the week or two before a Module Exam.
As homeschoolers we had heard of Apologia for years but this is our first year using it. I work professionally as a microbiolgist and my wife has worked as a chemist and we are both impressed at how well the material is presented.
