In this interactive lesson, students learn about categories of plants, plant parts, life cycle, what plants need to grow, and edible plant parts.

A very simple introduction to the various types of growth and reproductive styles of common plants.

A collection of lesson plans for specific age levels to help students gain a better understanding of animals, plants, and people, and how they affect each other in ecosystems. Many of the activities provide discussion questions and charts to supplement these lessons.

Inspector LePlant and his friends look at the world of plants in this site for younger students. Features include the parts of plants and the seven basic requirements that plants need to survive as well as a short quiz.

Become a detective and solve the soil mystery! To solve the case you must discover what soil is, why it's important, and in what kind of soil do plants grow. You will find out the four components of soil along with the different soil types. Have fun detecting!

Activity where the correct labels must be matched to the different parts of a flowering plant.

This site from the University of Illinois explains basic principles of weather radar, its development, and application to weather forcasting. Includes section on how wind patterns are shown using doppler radar.

A "research and service" organization, the ISGS's "programs encompass geologic mapping, water and mineral resources, environmental and engineering geology, geochemistry, and education." Read articles, view maps, study old aerial photographs or learn about how to hunt for fossils. There is a great deal to explore here.

Site contains information on the statistical term standard deviation. It gives a definition and shows how to calculate it. It has a link to information on the absolute value of a deviation and how the topics are related.

Page describes Photosynthesis in great detail. Provides an extensive amount of links on all different aspects of photosynthesis. Very thourough.

This resource is the beginning of a series of pages that demonstrates the diffference between the mean and median of a group of numbers. Uses bar graphs to display the data.

Animation and text explain the water--or hydrologic--cycle, which is the process that water undergoes in nature.

What causes wind? How does wind affect our weather? This website is neatly organized into topics about pressure, gradient force, Coriolis force, geostrophic wind, gradient wind, friction, boundary layer wind, and sea and land breezes. Text is supported with pictures, videos, and graphs.

Rainbows and sunsets are called "atmospheric optics". They can be caused by light being absorbed, reflected, scattered, refracted, or diffracted by particles in the atmosphere. Learn all about different atmospheric optics along with beautiful photographs in this website.

This site contains a couple different ways that one can forecast the weather. Methods include the Climatology Method, the Analog Method, and Numerical Weather Prediction.

Water is the source of life on earth. It exists in many forms and is constantly changing. The circulation and conservation of earth's water is called the hydrologic (or water) cycle. Find out how water evaporates, condensates, precipitates, transpires, and is transported around the earth.

A scholarly examination of the physics of dance, this reads like the notes of a lecture, so requires some intense reading. It presents a glossary of physics vocabulary, particularly as terms (e.g., torque, static balance) relate to dance movements. Goes on to explain the physics of turning and jumping, and how body size affects the physics.

Excellent and comprehensive site created by the University of Illinois at Urbana-Champaign, Beckman Institute for Advanced Science and Technology. The site has resources about and links to information on a large number of topics in biophysics.
