The Atomic Archive indexes a variety of downloadable and viewable videos which are present at the site. Some videos are have virtual reality feature, allowing the visitor to rotated and explore features an object (e.g., a bomb).
Site provides the ABC's of nuclear science including radioactivity and gamma decay to fission and comic rays.
Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.
By the end of this section, you will be able to do the following:
Describe advantages and disadvantages of asexual and sexual reproduction
Discuss asexual reproduction methods
Discuss sexual reproduction methods
In the following video Paul Andersen explains how the nucleon number and charge is conserved in all nuclear reactions and radioactive decay. Fission, fusion, alpha decay, beta decay, and gamma decay all conserve the number of neutrons and protons, as well as charge. [8:27]
Paul Andersen explains how nuclear energy is released during fission of radioactive uranium. Light water reactors, nuclear waste, and nuclear accidents are also discussed along with the future of nuclear energy. [9:06]
Learn how scientists regulate a nuclear reactor in this animation-enhanced essay from the FRONTLINE Web site.
This animation from NOVA: "Battle in the War on Cancer: Breast Cancer" describes how oncogenes cause cancer and how cancerous cells can spread throughout the body.
This site from The Nobel Foundation includes the speech that was given by Irene Curie in accepting the Nobel prize.
This site has lesson plans and activities related to radiation. Activities include measuring radiation with a Geiger counter and observing radiation 'footprints' in a cloud chamber.
This video segment adapted from FRONTLINE looks at nuclear fission as an energy source that can be used to generate electricity. [2:49]
This video segment adapted from FRONTLINE looks at nuclear fission as an energy source that can be used to generate electricity.
Analyze nuclear fission chain reactions and how to prevent them as well as explore ways to control nuclear reactions through these simulations.
What happens during nuclear fission and what a nuclear chain reaction is. How nuclear fission can be used to produce energy and the pros and cons of using that energy.
