Entire Science Unit - Energy and the Environment - Powerpoint found at www.sciencepowerpoint.com

This is a video sample of a powerpoint presentation that can be found at www.sciencepowerpoint.com which is one part of a teaching unit for students in grades 5-10. Each second represents one slide on the actual Powerpoint Presentation. This is sample video is for the first 1/3 of the TINSTAAFL Unit (There Is No Such Thing As A Free Lunch), 788 more slide available on the full version. THE TINSTAAFLOFE Unit covers science topics associated with Matter, Phase Change, Gas Laws, Energy, Magnetism, EM Spectrum, Electricity, Thermodynamics, and Environmental Issues. (See list below for more topics covered). This unit includes an interactive and engaging Powerpoint Presentation of 1125 slides with built in class notes (Red Slides), lab activities, project ideas, discussion questions, assessments (Quiz Wiz), and challenge questions with answers. Text is in large print (32 font) and is placed at the top of each slide so it can seen and read from all angles of a classroom. Also included is a 12 page assessment (THE TINSTAAFLOFE) that chronologically goes with the slideshow for nightly homework and the end of the unit assessment, as well as a 8 page modified assessment. 20 pages of class notes with images are also included for students who require modifications, as well as answer keys to both THE TINSTAAFLOFE for support professionals, teachers, and homeschool parents. 30 video shorts (FLV files) are provided and a slide within the slideshow cues teacher / parent when the videos ...

Observing the Genesisof a Hurricane/Vortex NASA Satellite

Concentrated spheres, such as Earth, are surrounded by layers of light of equal pressures. Clouds float around the Earth in them. The reason they float in curves parallel to the Earth is because of these spherical equipotential planes of pressures which curve as the Earth curves. Curved pressures of light act as lenses to multiply and divide light radially. (Spiraling) Light rays which pass through curved planes concentrate to a point when projected through light lenses of space in the convex direction and decentrate when they pass through the concave direction --------------------------------------------------------------------- Vector Fields and Hydrodynamics Force fields have definite properties of their own suitable for scientific study.

It emits enormous amounts of radiation, which Tesla called "primary solar rays" (and lead to modern concept of cosmic rays). These rays in turn, hit various particles in space which give rise to much weaker secondary radiations. The primary ...

Curved mirrors - physics experiment

www.fizik.si A curved mirror is a mirror with a curved reflective surface, which may be either convex (bulging outward) or concave (bulging inward). Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices. The most common non-spherical type are parabolic reflectors, found in optical devices such as reflecting telescopes that need to image distant objects, since spherical mirror systems suffer from spherical aberration.

Wargame on half domescreen Test 1

We test the wargame in half domescreen of rear projection type. You feel a little 3D sensation when the screen is not plane. We will also try the 3D projector & stereoscopiska glasses with 3D games on this screen, and larger flat screens up to 108 ". We hope to appear on this new type of game screen resolution in 2010 at various arcades. The screen imaging is superb in reality. The monitor also works great running car racing and all types of games. Half dome screen with a projector that is 3D ready, and with ultra-short lens will not cost a fortune with us. This dome screen is a prototype. Those who want to test drive is welcome at our showroom in Örebro.

Essential Parts of a Microscope

The basic design of the microscope has not changed that much over time. They have evolved, but the basic concept is still the same. There are several key parts that many types of microscopes have in common. All of the parts of a microscope must function properly for the microscope to work well. If one part is substandard, it can render the microscope useless. The major parts of a microscope are the lenses, the arm, the tube, the illuminator, the stage, and the adjustment knobs.

There are two kinds of lenses on a microscope. The eyepiece lens, also known as the ocular lens is at the top of the microscope. This is the part that people look through. The ocular lens is not adjustable on most models. The objective lens provides much of the microscope's magnification. A microscope usually has a few different objective lenses that vary in strength. The objective lenses are contained on a circular part placed between the eyepiece and the stage. Different objective lenses are chosen based on their strength. When someone wants to use a different strength of objective lens, they turn the circular disk to put another lens over the stage.

Other than the lenses, the other parts of a microscope are the tube, the arm, the stage, the illuminator and the adjustment knobs. The tube connects the ocular lens and the objective lens. People look through the ocular lens and tube and see out of the objective lens at the bottom. The arm connects the lenses and the stage. It protrudes to the side and provides a handle to carry the microscope as well. The stage is where the object is placed for examination. Stage clamps secure the microscope slides to the stage. The microscope slides contain specimens such as blood or other liquids. The illuminator is below the stage. This part provides light to make the specimen easier to see. The illuminator is either an actual light or a mirror.

Most microscopes feature two adjustment knobs to help focus the lenses. The coarse adjustment knob is the larger of the two and brings the lens and the stage closer together. The fine adjustment knob is smaller and is used after the coarse adjustment knob to provide any small adjustments to bring the item into sharp focus.

These parts of a microscope are common to nearly all models. Some microscopes use slightly different parts. For example, electron microscopes use electron beams instead of illuminators.
