Has public speaking become a dinosaur? In the age of blogs, texting, Twitter and Facebook, has the traditional art of communication via spoken words, eye contact, vocal inflections and nonverbal gestures become less popular? Are gifted speakers those rare creatures born with charisma and unique style? The answer is definitely no. Accomplished speakers all have skills that can be learned, practiced and mastered by anyone with the desire to motivate and move others. Simply Speaking is a tool for teachers, students, and adult learners who wish to become proficient in their communication skills. The ability to express ones thoughts verbally to produce a clear message in spoken language is a vital skill. From highstakes situations, such as interviews or presentations, to social interactions, the ability to interact and communicate through speech and language is necessary for success in life. This DVD and guide set present examples of individuals who demonstrate the road to successful public speaking. They show how motivation and dedicated practice can help someone advance and become a polished presenter.
This program explores how arthropod biodiversity helps humans. Insects as diverse as cockroaches and honey bees, as well as other arthropods such as millipedes and centipedes, are shown to be both decomposers and producers. The functions that these "bugs" perform are therefore essential to the health of our planet and us.
While most volcanoes occur at plate boundaries, not all do, as is evident in this map.
Children often resemble their parents, but the mechanics of heredity were not well understood until the 1860s when statistician/scientist Gregor Mendel identified all the basic laws of inheritance, including the revolutionary notion that there is a double set of genetic instructions.
This episode focuses on the adaptations of arachnids and insects. The search starts in the backyard at night time, exploring for spiders who are nighttime builders. These backyard predators are described as astonishing architects that design and build intricate silk webs with safety lines, places where they anchor themselves to wait for unsuspecting insects. Their amazing adaptations: speed, size, silk webs, and venom, make them efficient predators. In the morning the exploration continues with a look at several insects living above and below the water's surface (mosquitoes, whirligig beetles, caddis flies, and dragonflies). More amazing adaptations are introduced including incomplete metamorphosis, eye development, and remarkable breathing apparatus.
This activity was developed for6th grade classrooms studying the Solar System, though can probably be used in a variety of settings. Students will be able to: • Draw motion of planets, Moons and satellites. • Draw diagrams to show how gravity is the force that controls the motion of our solar system. • Identify the variables that affect the strength of the gravity. • Predict how motion would change if gravity was stronger or weaker. The Student Activity includes pre- and post-labs, but these can be excluded. Standard 6.1.2 Develop and use a model to describe the role of gravity and inertia in orbital motions of objects in our solar system.

Visible light passing through a glass prism separates into different component colors.
Elliot lives in America and Kailash lives in India. They are pen pals. By exchanging letters and pictures, they learn they both love to climb trees, have pets, and go to school. Their worlds might look different, but they are actually similar. Same, same - but different!

This live-action video program is about weather. The program is designed to reinforce and support a student's comprehension and retention of the word through use of video footage, photographs, diagrams and colorful, animated graphics and labels. Viewers will see and hear the word used in a variety of contexts providing students with a model for how to appropriately use the word. Related words are also used and reinforced with visuals and text.
Guess who's selected to give an exhibition of a slam-dunk during half time of the big basketball game? Phoebe! The problem is Phoebe can't jump high enough. "If only gravity didn't pull on me!" she moans. Never one to be tied down, Ms. Frizzle sends the class into space and turns the Bus into a planet - with adjustable gravity! Basketball's a snap with low gravity and a riot with no gravity at all, but when there's way too much gravity, things get really heavy! With Paul Winfield as school principal, Mr. Ruhle.
Fertilization is the combining of male and female sex cells. When a pollen grain touches the top of the pistil, called the stigma, it forms a tube through which male sex cells travel downward into the ovary. An egg is fertilized inside the ovary.
In "Systems of Linear Equations I" students will learn to: solve a system of two linear equations by graphing, solve a system of two linear equations by substitution, determine how many solutions a system or linear equations has and explain how the number of solutions to a system can be determined from a graph and solve word problems using systems of two linear equations.
Program six looks at how science, engineering and biotechnology have led the way in providing a safe and healthy food supply as well as extending the shelf life of food products. This includes the scientific advances in food processing, spoilage prevention, and retaining nutrition. The preservation and packaging of food is fully explored.æ
On "Lifelines," a son writes an emotional letter to his estranged father; "Dictionary Cinema" explains how foreign words are listed in the dictionary; "Milestones" profiles a San Francisco/Bay Area adult learner, Enrique Ramirez, who shares his continuing education with his employer; "Street Beat" gives tips on highlighting text; and on "Sports Smarts", NBA Atlanta Hawks players LaPhonso Ellis and Alan Henderson demonstrate how to figure out time and distance on a map when planning a trip. Plus, a pop quiz about word origins, and "Buzzword" explains the word "reconcile."
When the principal, Mr. Ruhle (Paul Winfield), has to go away for a few days, he leaves his beloved chicken, Giblets, in Dorothy Ann's care. Unfortunately, the minute Mr. Ruhle is out the door, Giblets flies away. How will DA ever find another prized Rhode Island Red to replace Giblets? Where do you get chickens anyway? And which comes first, the chicken or the egg? The next thing DA knows, Ms. Frizzle and the class are on a field trip to see how eggs are made "from the inside out"! But will this egg have everything it needs to become "Giblets the Second"?
