Pollination and Fertilization
Insects usually assist in the fertilization of flowering plants. Fertilization occurs when one sperm nucleus fuses with the egg nucleus. Other sperms form the endosperm by fusing with egg cells. Short video clip discusses pollinators and parts of the flower like the male stigma, female stamen, ovary and embryo. Run time 01:50
Flowers: The Seed Producers

Methods of Pollination
This video covers the various ways that a plant can be pollinated, including specific plants for each type of pollination. Â Insect pollination, wind pollination, cross pollination, and self-pollination.Run time 03:57.
Floral Arrangements
It's a problem faced by all seed-producing plants: how to get their pollen into the flower of another plant of the same species. This video segment from Sexual Encounters of a Floral Kind explores some of the strategies plants have evolved to solve the problem. Closed captioning included. Run time 03:08.
Energy Flow
Through the process of photosynthesis, plants harness the sun's energy and in so doing make many forms of life -- including human life -- possible. What path does this energy follow, and how is it transferred from one type of organism to another? In this feature, adapted from Interactive NOVA: "Earth," learn why 400 pounds of corn can't be converted into a 400-pound cow.
Food Chains
Learn about food chains and how they combine to form complex food pyramids. This short, computer-animated video will briefly cover the following key concepts: food chains, producers/consumers, the relationships between plants and animals in a food chain, the role of sunlight in a food chain, the role of plants in a food chain, the role of consumers in a food chain, food webs, food pyramids, and balancing a food pyramid. The video ends with a 10-question, fill-in-the-blank quiz. (The video do
Declaration of Independence
On June 7, 1776, Virginia delegate Richard Henry Lee introduced to the Continental Congress a resolution: "That these United Colonies are, and of right ought to be, free and independent States." He further called "for forming foreign Alliances and preparing a plan of confederation." Lee's resolution announced America's break from England, but members of Congress believed a more formal explanation was needed to unify the colonies, secure foreign assistance, and justify their actions to the world.
The Declaration of Independence: Ideas for a New Age
This 17 minute examines the basic principles and concepts set forth in the Declaration of Independence, as well as the American leaders, their ideas and the historical events that resulted in the document. Good details. Best used with a timeline and a word list. Many items need a great deal more explanation, but the video is a good start.
Has video quiz, too.
The Stamp Act
Video accompanied with text dealing with the Stamp Act. "The peace treaty that ended the French and Indian War in 1763 eliminated New France as a military threat to the British colonists, and marked the start of the march toward American independence. The war effort, and British Prime Minister William Pitt’s decision to retain large numbers of troops in the American colonies after the conflict, doubled Great Britain’s national debt.
In an effort to raise revenues, Parliament enforced
Learn French-Repeat After Me, # 1
The speaker says 5 phrases twice:
Bonjour, Bonsoir, Bonne Nuit, Au Revoir, Salut.
The English translations are the bottom of the video. The video is a good way to start learning French.
Radish seeds sprouting: time lapse
A great example of germination. This time lapse video shows how radish plants go from seeds, to seedlings, to plants in just nine days. Amazing how fast the radishes grew. Time lapse sequence set to take a frame each 14 minutes 24 seconds. The time lapse spans 9 days. Two 90 watt compact floresecent lights where used for both the camera shooting light and the grow lights. The lights were set on a timer for 18 hours on and 6 off (for the health of the plants). The jump in the video is the 6 hou
Differentiation in Plants - Elementary Science
This is a short, animated narrated video (01:40) gives a very brief overview of the differentiation in plants. Some of the narration is accompanied by English captions.
Plant Physiology: Phototropic Response
Growth in plants reflects the way in which the interact with the environment. Using time lapsed photography, his professional video shows how a plant responds to light and gravity. Includes narration. Run time 02:36.
Hydroponics
Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil. Visit the VanScoy farm to see how its hydroponic operation is progressing.
Biome in a Bag
The distribution of plants and animals around the world corresponds closely to global patterns of temperature and rainfall. This is why two forests half a world away from each other will often have very similar organisms living in them. In this ZOOMSci video segment, a cast member of ZOOM creates a self-contained biome and explores evaporation, condensation and precipitation. The video also addressed what a plant needs in order to grow. Closed captioning included. Run time 03:24.
Plants-in-Motion
This interactive activity adapted from Indiana University features time-lapse videos that reveal the movement and growth of plants in their pursuit of light. Although plants have no choice about where they are rooted, they do respond to environmental cues in ways that enable them to survive. This interactive site includes five videos using time lapsed photography (no audio) with written explanations. The videos include: seed germination and gravity, light and dark responses, twining vines, pl
Sock Seeds
The experiment demonstrated in this ZOOMSci video segment--wearing an old sock through a grassy or weedy field, planting the sock, and watching what grows--will not only give young scientists a better idea of the kinds of plants growing in their area, but will also help them begin to think about the evolutionary strategies of plants. Closed captioning included. Run time 03:00.
How to Learn Algebra
When learning algebra, it helps to avoid becoming intimidated and
to start off by learning simple problems to build confidence. A standarized test prep teacher show how to isolate variables to solve algebra problems. with examples on a whiteboard. Narrator speech is shown as text on bottom of screen.
Subordinate Conjunctions Rap Song
A subordinate conjunction rap. The lyrics start with dependents won't last unless they are attached and then rap music is added to the lyrics. This non professional production rap lesson takes place in a bedroom.
Roosevelt Fights in Spanish American War
In this The Presidents video, learn that at a time when the great nations of the world were expanding their empires, many feared that if America did not start taking colonies, it would risk being overpowered.This video does a good job of explaining why America acted as it did and Roosevelt's work in that regard. Gives good detail.
