life sciences

"Explore this fascinating timeline history of life science! What are cells, heredity, evolution, ecosystems, and photosynthesis? Who first studied these concepts? And who later built on and expanded the work of those early thinkers?"--.

Looks as signigicant scientific breakthroughs, including cell biology, using energy, cloning, photosynthesis, and more.

A teacher's guide to using fiction and nonfiction picture books to teach life sciences.

Introduces migration and hibernation of animals.

Contains over twenty segments that introduce or highlight topics related to animals, cells and genetics, human biology, ecosystems and biomes, and bacteria, plants, and other organisms, and looks at the questions of what science investigations are, and how they work.

Explains and illustrates the interdependent relationships between plants and animals that enable their survival. Discusses out how plants and animals interact, cooperate and compete and shows the constant exchange of nutrients and gases that assures their interdependency. Explores why animals are vital to the reproductive process of many plants and how animals rely on plants for food and shelter. Concludes with an experiment that explores how plants depend on animals for pollination and whether or not a flower's color is responsible for reproductive success.

Explores plant diversity, explaining how plant species have evolved in every habitat on the planet. Looks at the differences between nonvascular and vascular plants and the development of seeds. Also identifies the differences between cone-bearing gymnosperms and flowering angiosperms. Examine the structures different plants have developed to adapt in their environment and explore the effects of climate on plant biodiversity using a hands-on experiment.
