Full-color materials help busy teachers present fun-to-do activities. Each standards-based lesson has one or more clearly stated objectives. Topics covered include: the five senses; plants; animals; life cycles; the human body; the water cycle; seasons; fossils; dinosaurs; natural resources; solids, liquids & gases; magnets; the concepts of sink and float.

The emergence of CRISPR/Cas9 technology has revolutionized gene editing. The Nobel prize for chemistry was awarded to Emmanuelle Charpentier and Jennifer Doudna, the scientists responsible for its discovery, in 2020 and it is considered the frontier of sophisticated medical science. This technology contains the promise that both gene therapy and eugenic control of human evolution is possible, even plausible, in our near future. This book looks at these developements in the context of the history of previous social and scientific attempts at genetic editing, and explores the policy and ethical challenges they raise. It presents the case for altering the human germ-line (which contains and controls hereditary genetic information) to eliminate a large number of genetic diseases controlled by a single or few genes, while pointing out that gene therapy is likely to be ineffective for diseases with more complex causes. In parallel it explores the possibility of genetic enhancement in a set of case studies. But it also argues that, in general, genetic enhancement is ethically problematic and should be approached with caution. Given the success of CRISPR/Cas9 gene editing, and the explosion of related techniques, in practice it would be virtually impossible to ban germ-line editing in our future. A more useful goal is to put regulation in place, with oversight that represents the interests of society. That, in turn, requires an informed public discussion of these issues, which is the intention of this book.

Melvin learns how to deal with disappointment.

Inquiry-based and easy-to-follow activities help students develop positive attitudes toward science. The experiments are aligned with national standards and cover the areas of physical, earth, and life science as well as health.

The next wave of science writing is here. Editor Max Brockman has talent-spotted 19 young scientists, working on leading-edge research across a wide range of fields. Nearly half of them are women, and all of them are great communicators: their passion and excitement makes this collection a wonderfully invigorating read. We hear from an astrobiologist at the Jet Propulsion Laboratory in Pasadena about the possibilities for life elsewhere in the solar system (and the universe); from the director of Yale's Comparative Cognition Laboratory about why we keep making the same mistakes; from a Cambridge lab about DNA synthesis; from the Tanzanian savannah about what lies behind attractiveness; we hear about how to breed plants to withstand disease, about ways to extract significance from the Interne's enormous datasets, about oceanography, neuroscience, microbiology, and evolutionary psychology.

Over 100 sight words featured, including 50 reproducible sight word activity pages, simple lesson format to maximize learning of early literacy skills, and bonus activity pages for extended practice.

In this long-awaited book, Timothy J. Lensmire examines the problems and promise of progressive literacy education. He does this by developing a series of striking metaphors in which, for example, he imagines the writing workshop as a carnival or popular festival and the teacher as a novelist who writes her student-characters into more and less desirable classroom stories. Grounded in Lensmire's own and others' work in schools, Powerful Writing, Responsible Teaching makes powerful use of Bakhtin's theories of language and writing and Dewey's vision of schooling and democracy. Lensmire's book is, at once, a defense, a criticism, and a reconstruction of progressive and critical literacy approaches.

A collection of activities designed to teach such critical science skills as observing, predicting, ordering, exploring, sorting, and creative thinking.
