With the help of over 7,000 of the world’s best wildlife filmmakers and photographers, conservationists and scientists, Arkive.org featured multi-media fact-files for more than 16,000 endangered species. Freely accessible to everyone, over half a million people every month, from over 200 countries, used Arkive to learn and discover the wonders of the natural world. Since 2013 Wildscreen was unable to raise sufficient funds from trusts, foundations, corporates and individual donors to support the year-round costs of keeping Arkive online. As a small conservation charity, Wildscreen eventually reached the point where it could no longer financially sustain the ongoing costs of keeping Arkive free and online or invest in its much needed development. Therefore, a very hard decision was made to take the www.arkive.org website offline in February 2019.

Blood - we can't live without it! blood; plasma; blood cells; blood types; blood transfusion; platelets; immune system; anaemia; clotting; bleeding; serum; antibodies; A; B; AB; O; antigens; rhesus; rh+; rh-; iron; periods ; Contents Blood is the fluid that keeps our bodies going. It is a transport system that carries oxygen and the essential chemicals to where they are needed in the body. At the same time it picks up the waste that the different parts of the body no longer need and delivers that waste to whichever part of the body is responsible for getting rid of it. It helps us fight infections and keep our body healthy. It carries heat around our bodies, to keep our fingers warm and stop our brains from overheating.More than half of blood is plasma. Sometimes people need extra blood because they have lost more than the body can make in a short time or they are not making enough red blood cells (this is called anaemia (say an-ee-me-a)). Type A blood can go to anyone who has type A or AB. Blood is amazing.
Stellarium Science Experiments for Kids" Science experiments for kids explain everyday mysteries like what causes rain, answer questions about form and function, and simplify concepts like symmetry and capillary action. They're fun, they're fascinating, and they're a great way to spend time indoors on a cold or rainy day. Forget beakers and Bunsen burners, exploding chemicals and complex instructions. These science experiments are safe and simple, relying on materials that you have at home. Follow the links below to learn how to conduct simple science experiments: Capturing Leaf Vapor Measure water vapor from a leaf to see if leaves breathe. Look-Alike Tests for Salt and Sugar Try some tests to see how these two compounds act differently. Reverse Garden Plant garbage instead of seeds, and find out what biodegradable means. Make Crystal Creations Add a sparkling crystal coat to decorations and paper sculptures. Liquid Density Test Try this test to see if all objects of the same size have the same density.

Welcome to ZipcodeZoo CK-12 People's Physics Concepts 1. Units and Problem Solving Units identify what a specific number refers to. 2. One dimensional motion describes objects moving in straight lines. 3. This chapter discusses parabolic and projectile motion, acceleration, and velocity. 4. In this chapter, we explore forces and Newton's laws. 5. Forces which cause objects to turn around continuously in a circle are known as centripetal forces. 6. Isaac Newton in a triumph of brilliance declared that there is one law of physics that governs motion and he unified “earthly” bodies and “heavenly” bodies with the The Universal Law of Gravitation. 7. The total amount of motion in the universe is constant. 8. When any two bodies in the universe interact, they can exchange energy, momentum, or both. 9. The third conservation law is conservation of angular momentum. 10. The development of devices to measure time, like the pendulum, led to the analysis of periodic motion. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20.
Bones: They’re alive! Without bones, your body would be a slippery bag of organs. But the stiff models of a skeleton that you’ve seen in science class (or as Halloween decorations) tell only half the story. That’s because “the skeleton does more than just hold you up,” explains Laura Tosi Bones are made of living, breathing cells. And they play all sorts of important roles, says Tosi, who directs the Bone Health Program at Children’s National Medical Center in Washington, D.C. Tiny ear bones conduct sounds that help us hear. Bone marrow — a soft, jellylike substance that fills the hollow interior of the body’s long bones — produces blood cells, both red and white. And that’s just for starters. Cells called osteoblasts (gray blobs forming an oval) create new bone tissue. Robert M. The skeleton crew The framework that gives your body shape is surprisingly busy. The body’s skeleton changes constantly. Cells called osteoclasts break down old bone through a process called resorption. Wikimedia Commons Asja/Flickr
BioEd Online: Biology Teacher Resources, Lesson Plans is pleased to offer a new online series of podcasts and supplementary standards-based educational activities, research information, and links. National Space Biomedical Research Institute (NSBRI) researcher, Dr. Babs Soller of the University of Massachusetts Medical School, has been working to develop techniques for non-invasive measurement of blood and tissue chemistry. Her work can be used to help monitor the health of astronauts in space. National Space Biomedical Research Institute (NSBRI) scientist Scott Dulchavsky has developed a technique to train space flight crews to conduct medical-quality ultrasound imaging in space. David Dinges, a professor at the University of Pennsylvania School of Medicine, is working with the National Space Biomedical Research Institute (NSBRI) to develop a test that helps astronauts to gauge fatigue and stress during long missions in space.
Make Crystal Creations" You can make crystal creations as an easy science experiment for kids. Dip decorations and paper sculptures in a crystal solution, and watch them crystallize overnight! What You'll Need: Waterproof table coveringwaterSaucepanSugarPlastic cupsChenille stems (pipe cleaners)StringScissorsPencilsFood coloringIndex cardsEpsom saltsAlumPermanent markersPie pan Step 1: Cover your work surface. Step 2: Heat a cup of water until it begins to steam. Step 3: Remove the cup from heat, and stir in 2 cups of sugar. Step 4: Mold chenille stems into decorative shapes (star, heart, cat, initials). Step 5: Tie one end of a piece of string to a chenille stem shape and the other end around a pencil. Step 6: Leave the shape overnight, and then remove it from the solution and let dry on a paper towel. Step 7: When dry, the decorations will be covered with shiny crystals. For larger crystals, allow the chenille stem to soak longer in the solution. To make a crystal sculpture, fold an index card in half.
Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things.
