  • Meiosis is important in assuring genetic diversity in sexual reproduction. Use this interactive animation to follow Meiosis I (reduction division) and Meiosis II in a continuous sequence or stop at any stage and review critical events.
  • This animation demonstrates the stages of mitosis in an animal cell. Use the control buttons in the upper left to run the complete animation. Click on any intermediate stage (for example, Anaphase), and see a representative still frame.
  • Do you know how to make your home a safe space during an earthquake? The more you do before an earthquake shakes your space, the less damage you will have--and the more points you will earn in this game. Compete against your friends and family to see who can earn the most points!
  • Welcome to the CELLS alive BioCams. In these BioCams, you will get to learn about cancer and bacteria cells. However, these are a bit different from "livecams" you might find elsewhere on the web - these repeat at daily or shorter intervals in order to convey information on biological rhythms.
  • This Environmental Protection Agency (EPA) climate change kids page is all about global warming. Exploring the movie on this site will help you to learn about: greenhouse gases, solar rays, infrared rays, deforestation, and emissions. The site also allows you to test your knowledge by taking a global-warming quiz.
  • The Environmental Protection Agency (EPA) climate change kids’ page will help you to understand how global-warming can change the way the water cycle works. The water cycle movie on the site has six scenes which discuss the cycle, water storage, water movement, extreme cycle, wet cycle, and the dry cycle. This resource also includes a water cycle quiz to test your knowledge after the movie.
  • This great interactive resource allows you multiple opportunities to explore weather related concepts. After clicking start, you will learn how to report and predict the weather at the underground W.H.E.D weather caves! Each activity has three different levels, and each level is harder than the one before it. This resource also includes a teacher's guide (with pre- and post- tests) and links to additional weather related resources. These include a weather glossary, a Fahrenheit to Celsius & Celsius to Fahrenheit converter, and a link that provides information about interesting people in the weather field.
  • This animation explores the forces and processes that deform rocks by creating folds, faults, and mountain ranges. You will learn how landmasses move, see the resulting deformation, and learn how this deformation relates to plate tectonics.
  • This animation traces the formation of sedimentary rock. It starts at a beach environment where sea water minerals cement sand grains together. The animation concludes with a real microscopic image of sandstone showing both mineral grains and cement. The animation can be paused and rewound to stress important points.
  • This is a great site to help you learn about glaciers! On this webpage, you will learn what glaciers are, how they are formed, the different types of glaciers, their anatomy, how they move, and about glacial erosion. This site also has a model that helps you to understand glacial growth and retreat.
