This site from the Missouri Botanical Gardens provided a wealth of information about 12 of the biomes. There were many layers for the study of each of the particular biomes. In addition, there were links to further information about the study of plants.

This site has the most information of any of the sites I found. In addition to text and photographs, there are also videos, lesson plans, and information about the scientists who study the biomes.

This nonprofit site not only provides information on international heroes for students, but it also requests student reporters. Reports can be written or videos can be created. Pictures can also be uploaded.

This is the best online library I've come across. There are complete books online from 25 countries, in addition to the United States. Many of the books are in the original language, which would help tremendously if you had students who didn't speak English.

If you wanted to use a specific book in your classroom, but didn't have enough copies, this site could really help. It contains many complete children's books--both text and illustrations for younger children, older children, and young adults. In addition, there are activities in which students could engage.

This site, created by Scholastic, is jammed with activities for students and teachers. I personally like the authors and illustrators page, on which students can view videos about authors, and participate in writing workshops where authors give students tips on how to improve their writing in a specific genre.

This site is for K-8 students. Students can create their own book lists from among 7,000 titles. They can also take quizzes on the books once they've read them. The site was created by Sylvan Learning. There is information and resources for students, parents, and teachers.

If you are looking for reading strategies for elementary students, this site is wonderful. There are strategies for each of the components of reading (phonemic awareness, phonics, fluency, vocabulary, and comprehension) as well as writing. For each strategy, there is also a chart that recommends whether to implement the strategy before, during, and/or after reading.

This is an awesome site for elementary reading teachers and students. There are online activities for phonics, phonemes, vocabulary, site words, comprehension, book talks, and author sites to name a few. There are also games students can play while learning basic reading skills.

While some are concerned that technology will do more harm than good, this site contains articles about using technology to solve complex problems. Without technology, these kinds of activities would be impossible for students to perform.

Besides a rationale for the use of technology in the classroom, this site has lesson plans, printables, rubrics, articles, worksheets, and much more.

This NCREL site contains research results, factors to consider, and implications of using technology to improve student achievement.

This site has the NETS for teachers, students, and administrators. It also has resources, professional development, and research

This site provides a rationale for integrating ThinkQuests into the classroom: students learn important communication skills, teamwork, and technology skills. In addition, there is a library of over 7,000 websites created by students who have participated in a ThinkQuest competition.
