Building on the foundations of Science 1 and 2, Science 3 lessons acquaint students with a wider variety of minerals, animals, birds, and plants, as well as weights and measures, stars, and planets. A special section entitled "Reduce, Reuse, Recycle" introduces the concept of stewardship and how a student's actions affect the world around him.
This is the updated second edition, which means that although the material presented is nearly identical, the look has been enhanced to be more appealing for the "modern" child.
Subjects include the following:
- Sound: sound waves; travel through gas, liquid and solid; parts of the ear; pitch; quality
- Cells, Tissues, and Organs: cell structure; living things; microscopes
- Minerals, Rocks, Soil: crystals; uses; precious metals; igneous, sedimentary, and metamorphic formation
- Animals: with and without backbones; warm and cold blooded; plant and animal eaters
- Birds: characteristics; observation; identification
- Work: forces; power; people; horses; engines; air and water power
- Skin: layers; glands; fingerprints; care; hair; nails
- Plants: food and storage; helpful plants
- The Solar System: inner and outer planets; asteroids; comets; meteors
