Harcourt Science for Second/Third Grade

We finished the first Harcourt Science book in first grade and now we're advancing to the second book in their series.  Kolbe Academy splits the book between third and fourth grades.  Therefore, we will be doing half of the book this year for second grade.  This is because I have my second grader taking on new subjects for Latin and Spelling.  We are also participating in a co-op once a week.  We will not have the time to finish the entire book in one year with these other subjects and activities.  There are 18 chapters in the book and we will be doing 10 of them.  Each chapter comes with a manageable experiment.  Our science will consist as follows:
