The late Michael J. Spear, M.S., earned a Bachelor’s degree in Forest Biology at the College of Environmental Sciences and Forestry in Syracuse, New York. A concurrent degree in Biology was awarded by Syracuse University. His Master’s degree was earned through private and public colleges in the Hudson River valley. The father of seven children, Mr. Spear taught every level of science for grades 7 through 12. He was active in the pro-life movement and was the founder of a private Catholic high school.

“Our microscope salt crystals experiment. We had fun doing this project!” –Linda, CO

Recently I purchased Life Science and there is no comparison with the secular science textbook I had planned to use. It is, without question, a fantastic book. It is thorough and well written. I HIGHLY recommend this text and workbook.

The boys are looking at paramecium, pond water and mushroom spores under the microscope. The images are projected on the computer screen. These are some of the experiments in Life Science, which my son is really enjoying!

My son in 7th grade doing the big germ experiment in petri dishes in Life Science. He was so interested in what he saw growing later! This was a very neat experiment that he very much enjoyed!
