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.
A Bamboo Garden
Almost 30 years ago, Jerry Burton got rid of some mute swans from his pond and in return received a few bamboo plants. It was the start of a lifelong love of bamboo, which is now a full-time business. Run time 05:16.
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) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.
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.
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.
Biology: Why Are Some Ideas So Difficult?
Focuses on the need for conceptual understanding and examines the scope of student ideas by exploring the central idea of photosynthesis, that the substance of plants comes mostly from the air. This innovative workshop for teachers explores the reasons why teaching science is so difficult and offers practical advice to help you teach more effectively.
Introduction to Journey North
This program introduces the three sets of investigations that are featured in the Journey North program: Seasonal Migrations, Plants and the Seasons and Sunlight and the Seasons.
Workshop 5: Sunlight to Starch
n this program participants will explore how plants get their food. Starting with seeds, which have their own source of food, the program traces the growth of a plant, the development of chlorophyll in its leaves, and the production of sugar (and starch) in a process known as photosynthesis.
Workshop 6: Energy and Ecosystems
In this program, participants are shown that light energy that has been absorbed by plants during photosynthesis and transformed into chemical energy can now be transferred to other organisms. Energy is contained within food molecules such as sugar and starch made by plants, therefore when animals eat plants, or eat other animals, the energy is passed to them. However, the transfer of energy between plants and animals is inefficient and there are energy losses.
Math in the Real World
This is a photo slide show presentation designed to engage students to think about "How might math have been used to ...". showing several examples: a building, a space shuttle, a cell phone, etc. No narration. Thought provoking. Hosted by Slideshare. Viewer sets the pace by clicking through the 8 slides.
A Human Story of Computer Animation
It took 20 years of dreaming, planning and ingenuity to create Toy Story, the world s first computer animated full-length feature film, in 1995. It represented a significant departure from the long-established methods of animation, where artists would hand draw characters frame by frame, and painstakingly incorporate movement and color to complete a feature film. Today, thanks to advances in computing power and ingenious software, there is little separation between the refining of an idea and it

1)Mixed Cell References, Assumption Table Orientation, Range Functions and Inserting columns
2)Mixed Cell References in Formulas and the orientation of the Input Values
3)Formula Input Value setup is critical for efficient formula creation
4)The beauty of Excel is illustrated in this video: Amazing Efficiency example. (10:26)

Plants that Make Spores
There are ten basic divisions in the Plantae kingdom, and only 5 that are spore bearing. Spores are special cells used in asexual reproduction. Learn about the plants that make cells in this short clip. Examples and photos are provide for the mosses, liverworts, horsetails and ferns. (2:34)
Plant Examples of Asexual Reproduction
This short video is about plants that have not grown from seeds but are reproduced asexually. Some examples from the video include bulbs, liverworts, plants with cuttings, and strawberry plants with runners. Run time 02:56.
Liverworts, Mosses, and Ferns
This video gives a quick overview of some different types of spore-bearing plants. Dr. Matt von Konrat explains the reproduction of liverworts, mosses, and ferns to a high school group of students. Audio is poor but information is good. Run time 07:50
Peachtree Rock Heritage Preserve: The Longleaf Pine Ecosystem
Conservationists know that the Longleaf Pine Forests of the Southern U.S. consist of much more than just its trees. They are complete ecosystems of plants, animals and natural processes including fire, rain and soil mineralization. Estimates show that over the last century, longleaf pine ecosystems have dwindled to less than 3 percent. Once thought to be inexhaustible, these forests were exploited for their lumber and turpentine products. Today, restoring these habitats to pre-settlement conditi
