Kelp Forests  
This page, part of the Biomes of the World web site, has information on kelp forests and several useful links including frequently asked questions about oceans Voyage to the Deep This site examines hydrothermal vents.  Students learn what deep ocean vents are and about how they form.  There is a link, Creature Features,  where students can view Quicktime movies and pictures of a deep ocean vent and animals that inhabit the  ecosystem.  Another link, High-Tech Tools, explains the technology and tools scientists
use for deep- sea exploration.  
Earth's Surface

Earthquakes for Kids 
This page designed for kids by the U.S. Department of Interior is very informative and includes maps of recent earthquakes in the USA, Science Fair Project Ideas, puzzles and games, as well as online activities.     

Fossil Formation Animation 
This animation shows students the formation of a cast and mold, one way that fossils can form.  Casts are copies of fossilized plants or animals. Molds are hollow impressions of the fossil. This process takes thousands or millions of years.  

Patterns on Earth and in Space

Weather Conditions

Weather Wiz Kids 
This page explains which weather instrument measures what, and how the instrument works. This site also includes information on all aspects of weather including hurricanes, tornadoes, winter storms, and much more.

Weather Watch  
This interactive site from Scholastic allows students to 'test drive' the tools meteorologists use every day.  Students click on each tool for more information along with instructions on building it and using it in an experiment.

Chapter 2- The Oceans
Observe a Wave in Motion    
This page allows students to view an animation of ocean wave motion.  

What Does the Ocean Floor Look Like? 
This site contains graphics, maps, and interactive animations that helps students visualize what the ocean floor looks like.  Lesson 3 Chapter 3- Planets and Other Objects in Space

The Moon's Orbit and Rotation  
This page explains how Earth's moon is kept in its orbit.  It helps students understand lunar phases and tidal forces too.  
The Motions of the Earth and Moon  
This page answers questions about Earth's motions with text and graphics. Why is there day and night?  Why are there seasons?  Students also learn about the Moon's motions.  

Jupiter's Moons and Rings  
Students can view this site at three different reading levels, Beginner, Intermediate, or Advanced.  They learn about Jupiter's sixty moons and about who discovered Jupiter's rings, how many there are, how they were formed and their composition.  
Saturn's Moons and Rings 
Students can view this site at three different reading levels, Beginner, Intermediate, or Advanced.  They learn about all of Saturn's moons and rings. 

Galaxies Galore and More 
These web pages contain several online explorations and fun activities for students to complete.  They can build our Milky Way, Explore Galaxies, and play Galaxy Games. 
Space Missions 
NASA missions are varied.  This site allows students or teachers to click on a mission to learn more about its features and progress.  Students can explore related multimedia links also. 

Matter and It's Changes

States of Matter
This site allows students an opportunity to view an animation that represents a microscopic view of each state of matter.  Students can also view a table that summarizes the properties of gases, liquids, and solids.  The table identifies the microscopic behavior responsible for each property.  
Measuring Mass   
The activities on this site are targeted to middle school students but can be used by more advanced elementary students.  Students can learn how to use a triple beam balance and practice 3 interactive problems to solve the mass of the object.  
Floating and Sinking 
At this site students learn about one form of floating transportation, the hot air balloon.  They learn and how and why hot air balloons float.  Students can click on Virtual Flight to experience a 4 minute balloon flight over the Black Rock Desert.
