What is a Meteor? Video answers the question: What is a Meteor? A meteorite is a natural object originating in outer space that survives an impact with the Earth's surface. While in space it is called a meteoroid. When it enters the atmosphere, impact pressure causes the body to heat up and emit light, thus forming a fireball, also known as a meteor or shooting star. Very bright meteorites are called fireballs. On very rare occasions meteorites hit t
Planet Earth is a Tiny, Tiny Object in Space
Do you know how tiny Earth is compared to other planets and stars?
Earth is compared to Venus, Mars, Mercury and Pluto.
Then to Jupiter, Saturn, Uranus and Neptune,then to the Sun.
Then to Arcturus - the brightest star in the northen hemisphere, and other smaller stars - Pollux and Sirius. There is no narration, just English captions to accompany the images.
Our Sun is a tiny dot in the Milky Way! Earth is even smaller!
Information About Betelgeuse
There are fascinating images (some are computer-generated) in this video of the red supergiant star Betelgeuse. Features a surface video and a picture of the spectacular supernova explosion. When it explodes, it may become a Pulsar surrounded by a big nebula.
Computer simulations by Bernd Freytag. Suitable for older elementary, middle school, snd high school students.
The Sun
It's a pretty ordinary star, but everyone's heard of it! Explains symbols and details of the sun. This video explains the symbol of the sun, which is a circle with a dot in it. It also explains the different masses of star, remember the sun is a star! In this video various scientists discuss the Sun. Video is of good quality and is appropriate for students in middle school and high school. Run time 05:42
Animal Adaptations
This is a video clip from "Adaptations", a 14-minute award-winning elementary life science video produced by the Visual Learning Company. Â This brief clip gives an overall view of what animal adaptations are, and how they are different for different species of animals. Examples include herbivores with flat teeth, carnivores with sharp teeth and claws, and plants with broad leaves to capture sunlight. Run time 01:43.
Exchanges in the New World
Columbus’s famed voyage in 1492 joined two very different worlds. For thousands of years, Europeans and Native Americans lived completely separate lives, unaware of the others’ existence. When Columbus stepped onto the rocky soil of San Salvador, he started a historic chain of events that affected the lives of millions of people on both sides of the Atlantic.
Columbus and later explorers discovered a land unlike anything they had experienced. They encountered neatly patterned park-like
Garden safety for children
It can be fun to let young children play in a garden but experts warn of some of the dangers to look out for. Tools, chemicals and water are the biggest hazards; and certain plants and flowers also must be avoided. Â This video shares this important information.
School Uniforms
The benefits of implementing a school uniform policy including improving student achievement, decrease in peer pressure, save families money and gang issues.
Magic School Bus "Gets Eaten"
Join Ms. Frizzle and the class as they search for a connection between pond scum and tuna fish. Scum is a kind of algae and algae and tuna are part of the same food chain! This Magic School Bus episode will cover the following two concepts: (1) Living things are linked by what they eat and what eats them. and (2) Almost all food chains begin with plants. Run time 22 minutes.
Learn Why Animals Eat Other Animals
Crazy Chris shows you a real life food chain you can do right at home with your exotic pet. Chris uses lettuce, a cricket, and a tarantula to demonstrate a food chain. He then explains why some animals eat plants (herbivores) while others eat meat (carnivores.) Run time 03:00.

Role of the Sarcoplasmic Reticulum in Muscle Cells
The instructor in this video, Sal Khan, discusses the role of the sarcoplasmic reticulum in controlling calcium ion concentrations within the muscle cell. Mr. Khan uses the Paint Program (with different colors)Â to illustrate his points. Sal Khan is the recipient of the 2009Â Microsoft Tech Award in Education.
Color Quest
Children's Choice afterschool enrichment program: Life's a Lab - Science Club. In this lesson we explore the science of the colors of both white light and black ink, chromatography, super absorbent polymers, and the water and soil nutrient uptake function of root systems of plants.
Busy, Busy, Bees! Honey Bees and Drones
We all know of honey bees! These insects are famous for two things:
when they are angry, they sting, and it hurts! And they convert nectar
which they collect from different plants into a sweet, thick, golden
liquid we know as honey!
Bees live in hives composed of hexagonal spaces and their colonies
have clear hierarchies. The most important member of the hive is the
queen bee. The other kinds of bees are female worker bees which nurse
the eggs and
Parasitic Wasps & Aphids
Black wasps have their own tactics and methods when it comes to pest control. In this vdeo, the plants send out a chemical message to wasps when attacked by aphids. The wasps lay eggs in the aphids, and the larvae kill the aphids. Grades 5-12. 2 min.
How to Make a Paper Shuriken
An art teachers explains how to make a paper shuriken, or a paper ninja star. This requires using two pieces of paper of differing colors, and each piece is folded identically before linking them together.
Baroque Music - Corelli, Concerti Grossi, Opus 6/9 in F
Baroque music is characterized by its non-stop pace. Seventeenth-century composer Arcangelo Corelli, who achieved the type of status a rock-star has today, wrote a much-loved example. It is called Concerti Grossi, Opus 6, No. 9.
Bean Sprouts
Pairs of second-graders explore subtraction, based on the number of
plants sprouting from the bean-seeds they have planted. The importance of context for student understanding, and various approaches to problem-solving, are exemplified. NCTM Standards: concepts of whole number operations, reasoning, problem solving, communication.
Planning and Professional Development Workshop 8
In order to grow in their careers, teachers need a great deal of
sustenance. In this program, the teachers talk about the ways in which they fulfill this need as they develop individually and as members of a professional community. The group invites us into their classrooms to look at the way they have grown professionally, stimulated by their peers, their membership in professional organizations, and their willingness to seek out new thinking on literature and teaching literature. Dr. La
Field Bology
"Lessons from the Field" highlights the project-based, real-world approach to teaching science. The video segment follows a high school student who becomes motivated to learn when challenged to design his own experiment, work with professional mentors, and analyze and present his findings. This case study is excerpted from Learning That Works, a three-part teacher video series that explores the educational possibilities and benefits of firsthand applied science. Run time 06:12.
