Classification Why do we classify things? * Classification provides scientists and students a way to sort and group organisms for easier study. * There are millions of organisms on the earth! (approximately 1.5 million have been already named) Organisms are classified by their: * physical structure (how they look) * evolutionary relationships * embryonic similarities (embryos) * genetic similarities (DNA) * biochemical similarities Build-A-Body Overview Learn about the body's systems with this drag and drop game. Choose organs from the organ tray, and place them in their correct position within the body to create organ systems. Animal Adaptations Being able to adapt is a matter of life or death. Animals who can't adapt - die! For animals, adaptation is the idea that animals have developed features that help them to survive and thrive where they live. Some adaptations are purely physical. Fish have fins to help them swim and gills that let them breathe underwater.
Human Body Systems Global rating average: 0.0 out of 50.00.00.00.00.0 Learn about the different human body systems and how they function in these sites that are written for elementary students. Includes illustrations, animated movies, and online quizzes. Animal Adaptations (4/12) Wow! Every year my third graders do amazing work on their animal adaptation projects. Here are the animal adaptation power points that were just completed by my third graders this year. Our goal was to combine what we have learned about habitats, landforms, nonfiction reading and research to put these projects together.

Dental activities for students: Quizzes & lesson graphics - Tooth identification Animated-Teeth.com offers a number of quizzes (with pre-test study pages) that teachers and instructors can use as part of a classroom activity or online lesson aimed at educating students about dental health topics. Subjects include tooth identification and dental, oral and facial anatomy. The skill level required for each activity varies widely. Some of our most basic quizzes are designed for young children who are first learning about teeth, dentistry and the dentist's office (don't forget that February is Children's Dental Health Month).
Myrmedrome - A real ant colony simulator MYRMEDROME is an ant colony simulator which tries to imitate the ants’ life as well as possible without introducing artificial effects. The simulation is based on the fundamental principle that each ant is not enough intelligent to understand it lives in a complex community, nor it is able to organize tasks in its colony. Therefore, each ant lives and works following some simple rules interacting (unaware of it) with the others by chemical signals. These thousands of connections rise a self-organization of the whole colony, which leads an observer to believe that someone imposed some kind of strategy. Mother nature network These bizarre locations may seem like a series of elaborate movie sets, but they are real destinations that you might want to see for yourself.

Deep Time : A History of the Earth - Interactive Infographic Life on the planet started astonishingly early. The first living organisms, in the current model of evolution, are thought to be Prokaryotes1. The oldest known fossilised prokaryotes have been dated to approximately 3.5 billion years ago, only 1 billion years after the formation of the Earth's crust. Eukaryotes2 are more advanced organisms with complex cell structures, each of which contains a nucleus. Although incredibly hard to determine their origin, they are thought to have developed 1.6–2.1 billion years ago, although some research2 suggests eukaryotes being present even earlier than this. Around 1.1 billion years ago multicellular3 organisms are thought to have started to develop, most likely similar in form to plants such as green algae. 200 million years later true multicellularity had also evolved in animals similar in nature to today's sponges, which are organisms which can reassemble themselves.
