DNA & Genetic Engineering

Robert Snedden's introduction to DNA and genetic engineering is clear, age-appropriate, and well-supported by photographs and diagrams that help upper-elementary students visualize concepts that can otherwise feel abstract. As part of the Cells and Life series, it sits within a cohesive curriculum context, making it especially useful for homeschool science programs. Snedden explains what DNA is and how cells read it before moving into applied biotechnology including gene therapy and cloning — a logical progression that works well for the target age. The honest caveat is significant: genetic science has moved rapidly since the early 2000s, and some specifics are dated. Ethical and philosophical dimensions of biotechnology topics are touched lightly rather than explored. As a foundational introduction it still functions well, but supplementation with current sources is advisable. Worth it.
