Scientist creates lifelike cells out of metal
Scientists trying to create artificial life generally work under the assumption that life must be carbon-based, but what if a living thing could be made from another element? One British researcher may have proven that theory, potentially rewriting the book of life. Lee Cronin of the University of Glasgow has created lifelike cells from metal — a feat few believed feasible. The discovery opens the door to the possibility that there may be life forms in the universe not based on carbon, reports New Scientist. Even more remarkable, Cronin has hinted that the metal-based cells may be replicating themselves and evolving. "I am 100 percent positive that we can get evolution to work outside organic biology," he said. The high-functioning "cells" that Cronin has built are constructed from large polyoxometalates derived from a range of metal atoms, like tungsten. The metallic bubbles are certainly cell-like, but are they actually alive? The early results have been encouraging.
"Excell At Cells"
As of July 1, 2013 ThinkQuest has been discontinued. We would like to thank everyone for being a part of the ThinkQuest global community: Students - For your limitless creativity and innovation, which inspires us all. Teachers - For your passion in guiding students on their quest. Partners - For your unwavering support and evangelism. Parents - For supporting the use of technology not only as an instrument of learning, but as a means of creating knowledge. We encourage everyone to continue to “Think, Create and Collaborate,” unleashing the power of technology to teach, share, and inspire. Best wishes, The Oracle Education Foundation
Cells - The Building Blocks of Life
By Shyamala IyerIllustrated by Dr. Biology All living beings are made up of cells. Some of them are made up of only one cell and others have many cells. The adult human body is made up of about 37 trillion cells. WOW, that's a lot of cells. Cells got their name from an Englishman named Robert Hooke in the year 1665. If we are made up of cells what are cells made from? Look around at your house and houses around you. What are the building blocks of a cell like? If you take a look at your home you will notice it is enclosed by outer walls. Sometimes people think of cells as a balloon filled with fluid. The plasma membrane in cells have special structures that allow water and other food materials to pass in and out of the cell. Cells are amazing.

Human Body Board Game
Subjects Science --Life Sciences ----Biology Grade 3-5 [facebookbadge] Brief Description Students research a system of the body, write questions and answers on game cards in Word, and then play the using a game board template from Word. Objectives Students will: gain understanding of the basic facts about systems of the human body. select the most important facts about a specific body system. Keywords human body, anatomy Materials Needed[shopmaterials] Student access to computers equipped with Microsoft Word. Lesson Plan Before beginning this lesson with students, you'll need to create a template for the game cards. This lesson works best at the end of a unit on the human body, when students have acquired some basic knowledge about the various body systems (circulatory, digestive, etc.). Arrange students into groups of 2-3. Whether you decide to have students play the game in groups or as an entire class will determine the number of game boards you need.

What are Proteins
By Meredith Turnbough and Marcella MartosIllustrated by Sabine Deviche and Dr. Biology Legos are a familiar building block that have been used to create an almost unlimited number of shapes. If you have ever had to get inside a locked car or home you know that shape matters. If you don’t have the right key, you cannot open the door. The shape of the key is important. When you are building with Legos, you have to use the right shape bricks in the right combination to create your totally sweet fort, space shuttle, T-Rex, or whatever else you can imagine building. In living things, shapes also matter. Little Pieces A molecule of caffeine, the chemical in soda and coffee that makes you feel more awake. You are going to see the word "molecule” used in Venom! So a molecule is something that has mass but is very small. Kinds of proteins Proteins can be put into groups based on what kind of shape they have, whether or not they dissolve in water, by what they do, or in lots of other ways.
Easy Science Experiments
Hands-on science experiments at home or in the classroom are a fun way to engage kids and get them excited about science. Today’s sites house hundreds of easy experiments that can be done with supplies that you probably have around the house, or can get at the grocery store. Exploratorium: Science Explorer5 stars"Get messy, get airborne, get loud, get shocked!" San Francisco's Exploratorium hands-on science museum offers a sampler of thirty simple experiments excerpted from two "Science Explorer" books. Elsewhere they provide a hundred more experiments called "snacks" because they are both fun and easy.
