How Changes in Earth's Magnetic Field and Ionosphere Affect Us - Part 4
Part 4 in a discussion on How do changes in Earth's magnetic field and ionosphere affect us? Anya Strømme – EISCAT/SRI International. She’s working with very high power radar to study the aurora borealis which are better observed at higher latitudes. She’s studying particles coming into the atmosphere, heating it, generating currents—this is where our satellites fly…this impacts tv reception, GPS, cell phones in a much more dramatic way than we can imagine.

The Power House of the Cell
Mitochondria play host to one of the most important processes in your
body: cellular respiration. Taking in glucose and oxygen, mitochondria
produce energy, which they capture and package as energy-rich molecules of ATP. This video describes the structure and functions that give mitochondria their nickname: the powerhouses of the cell. Closed captioning included. Run time 05:47.
How does HIV spread from an infected cell to a healthy one? A team from the University of California, Davis, and Mount Sinai School of Medicine in New York captured the process on video for the first time. By dying viral particles with a fluorescent green dye, they were able to see the infection in action.
This is a video clip from "Adaptations", a 14-minute award-winning elementary life science video produced by the Visual Learning Company. 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. This video shares this important information.
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.
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.
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
"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.
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.
