Ronald D. Vale Science and Technology 2012-10-11T22:56:39 Course Related Materials http://www.oercommons.org/courses/nutrition-2-good-food-good-health In this activity from Science NetLinks, students use Internet resources to explore ways in which food provides energy and materials for their bodies. In the elementary grades, particularly the lower-elementary level, children know that there are different foods--some 'good' and some 'bad.' They also seem to understand that a person's height and size can depend on what he/she eats. In this investigation, students will use online resources to help them explore how food can affect their overall health.

In this lesson, student interactives are used to help students focus on the kinds of physical changes that children of their age range begin to undergo during puberty. Science and Technology Social Sciences 2012-09-25T18:59:05 Course Related Materials http://www.oercommons.org/courses/growth-stages-1-infancy-and-early-childhood This Science NetLinks lesson is the first of a two-part series aimed at introducing students to the different stages of physical growth and development in human beings from birth to 18 years of age. Through the use of student interactives, this lesson helps students become better aware of all the natural physical stages of growth children experience in the first five years of life. Science and Technology Social Sciences 2012-09-25T18:59:05 Course Related Materials http://www.oercommons.org/courses/what-happens-in-the-first-9-months The following statement, written by Samuel T. Coleridge, ties in well with the study of human development to which students are introduced during these grades: "The history of man for the nine months preceding his birth would probably be far more interesting, and contain events of greater moment, than all the three score and ten years that follow it." This lesson will enhance students' studies by providing them with the chance to explore human development using Internet resources that contain text, drawings, photos, and video about human development.

Students discuss research methods and examine factors that may affect aging. In this lesson, students also review a website to learn about cross-sectional and longitudinal studies of aging. Science and Technology 2012-09-25T18:59:03 Course Related Materials http://www.oercommons.org/courses/taking-care-of-a-baby In this Science NetLinks lesson, students are introduced to the basics of how a baby grows inside its mother until its birth. They then consider and discuss the birthing process. Then students are led into the third part of the lesson, which focuses on the early years of infancy. They are prompted to think about the kinds of basic needs infants have and the critical role adults play in ensuring a baby's healthy physical, emotional, and cognitive development. Science and Technology 2012-09-25T18:58:58 Course Related Materials http://www.oercommons.org/courses/hatching-chickens This lesson, from Science NetLinks, is intended to help students realize that they can learn a lot about chickens -and animals in general - through close observation. Students begin the lesson by expressing what they know about chickens in general and then are encouraged to think and talk about how eggs hatch into chicks and the kinds of special things that are needed to care for eggs/chicks. Science and Technology 2012-09-25T18:58:57 Course Related Materials http://www.oercommons.org/courses/adolescent-slowdown This Science Update, from Science NetLinks, focuses on one reason why puberty is such a notoriously difficult time for kids. It's a time when the world feels like it's speeding up. According to new research, part of that feeling may come from the fact that adolescents' brains are actually slowing down. Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLink lessons and other related resources.

But what happens when her baby grows up? In this Science Update, you'll hear about a recent study that suggests that malnutrition in the womb can come back to haunt you well into adulthood. Science and Technology Social Sciences 2012-09-25T18:58:54 Course Related Materials http://www.oercommons.org/courses/crystal-meth A single hit of the drug crystal meth may be enough to cause permanent birth defects. That's according to University of Toronto pharmacologist Peter Wells, who led a study using pregnant mice. Just one dose of the drug led to poor motor coordination and other neurological problems in the mice's offspring.Why is meth so harmful? This Science Update answers this question and has a detailed text description of the research as well as links to resources for further inquiry. Science and Technology Social Sciences 2012-09-25T18:58:53 Course Related Materials http://www.oercommons.org/courses/dolphin-brains Dolphins and other marine mammals have pretty big brains compared to the size of their bodies. That's one indication of high intelligence, and anyone who has seen them perform at an aquarium or zoo can attest to that fact. Science reporter Bob Hirshon introduces us to one scientist who's trying to find out how dolphins got so brainy. Science and Technology Social Sciences 2012-09-25T18:58:53 Course Related Materials
