Introduction to Nuclear Chemistry | Chemistry for Majors Outline of Nuclear Chemistry Nuclear Structure and StabilityNuclear EquationsRadioactive DecayTransmutation and Nuclear EnergyUses of RadioisotopesBiological Effects of Radiation The chemical reactions that we have considered in previous chapters involve changes in the electronic structure of the species involved, that is, the arrangement of the electrons around atoms, ions, or molecules. Nuclear structure, the numbers of protons and neutrons within the nuclei of the atoms involved, remains unchanged during chemical reactions. This chapter will introduce the topic of nuclear chemistry, which began with the discovery of radioactivity in 1896 by French physicist Antoine Becquerel and has become increasingly important during the twentieth and twenty-first centuries, providing the basis for various technologies related to energy, medicine, geology, and many other areas.

Bioman Biology: The Fun Place to Learn Biology! Atoms: Electrons Electrons are the negatively charged particles of atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus. Electrons are extremely small compared to all of the other parts of the atom. The mass of an electron is almost 1,000 times smaller than the mass of a proton. Electrons are found in clouds that surround the nucleus of an atom. Electrons play a major role in all chemical bonds. The Radiation Belt Storm Probes (Science@NASA Video)

Bad Science RADIOACTIVITY The atoms of some chemical elements are unstable. They try to rearrange themselves to make more stable atoms. In the process, they give off radiation particles or tiny bursts of radiation. This process is called radioactivity. Although radioactivity can be harmful to people, it can also be important to us in everyday life. It is used to make nuclear energy and preserve food, and it also plays a vital role in the treatment of cancer. Some types of radioactivity are harmful, because they damage or destroy the tissues of the human body. The three types of radiation are alpha and beta particles, and gamma radiation, named after the Greek letters above. An alpha particle is made when the nucleus (central part) of a large, unstable atom rearranges itself, or decays, to make a smaller, more stable atom. Beta decay is quite different from alpha decay. Radioactivity can cause cancer if it harms healthy cells in the human body.

Radioactivity for Kids - Science Games and Videos Radioactivity for Kids Radioactivity, also known as radioactive decay, is a process by which a radioactive isotope loses subatomic particles (helium nuclei or electrons) from its nucleus along with usual emission of gamma radiation, and becomes a different element. In a large collection of atoms, there is a definite time, called the half-life of the isotope, after which one-half of the total number of nuclei would have decayed.

The Photosynthesis Cycle" The Earth's atmosphere is mostly composed of nitrogen. Oxygen makes up just 21 percent of the air we breathe. Carbon dioxide, argon, ozone, water vapor and other gasses make up a tiny portion of it, as little as 1 percent. But some scientists believe that the Earth's atmosphere would never have contained the oxygen we need without plants. Photosynthesis is a complex reaction. 6CO2 + 12H2O + Light -> C6H12O6 + 6O2+ 6H2O In other words, while we inhale oxygen and exhale carbon dioxide, plants inhale carbon dioxide and exhale oxygen. Without the sun to feed plants (and the plants to release oxygen), we might not have breathable air. Obviously, plants are important, but not just because they give us food to eat and oxygen to breathe.
MPI - Fisheries | Student & Teacher Resources (Starfish) | Staff Room Starfish As an island nation, many New Zealanders have strong connections with the sea. Whether swimming, surfing, lying on the beach, exploring the rocky shore or fishing, the ocean plays a huge role in our national identity. Commercially, our fisheries earn the country more than $1.3 billion annually – fishing is one of our key primary industries. Making sure that our oceans and fisheries are healthy and sustainable into the future is of vital importance to all New Zealanders. This resource has been designed for teachers of students in years 7 to 10. Fish for Tomorrow This educational programme draws attention to high, medium and low risk areas in terms of New Zealand's marine species and looks comprehensively at customary rights and regulations. This resource has been developed as a learning tool for Years 4, 5 and 6 from the New Zealand Curriculum and it takes the form of a DVD and resource kit containing DVD-based activities.
How Are We Preparing Students to Be Tomorrow's Innovators? | Suzie Boss Follow the discussion on Empowering Education Leaders to Innovate on Wednesday Jan. 30 at 3pm PST. According to the just-released Gallup-HOPE index for 2012, developing a world-changing invention is an aspiration shared by 42 percent of youth in grades 5-12. That's good news. Given the scale of challenges facing us--in our own backyards and around the globe--it's easy to see that we're going to need every good idea the next generation has to offer. What are schools doing to prepare today's students to be tomorrow's innovators? Given the right conditions, students eagerly step up to the challenge of becoming not only better thinkers, but also makers, doers, and problem solvers. What can school leaders do to encourage more of these kinds of experiences? Are you willing to take risks? Do you know how to network? Do you help good ideas grow?
