Boil, Boil, Toil and Trouble: The International Boiling Point Project 
Grades: 3-12
Ongoing? Yes
Students around the world report the boiling point of water in their locale. By analyzing data across sites, visitors can see relationships among boiling point, elevation, and a number of other factors. This is a solid example of multi-disciplinary (as well as multi-participant!) learning.

Bucket Buddies
Grades: 1-5
Ongoing? Yes
Bucket Buddies is a collaborative environmental study that poses the question “Are the organisms found in pond water the same all over the world?” Students collect water from a nearby pond and identify the macro invertebrates present. The findings from all participants are shared in the Discussion Area of the Web site, giving all groups of students the opportunity to compare their data with other students’ data from around the world. Corresponding lesson plans are provided in the Teacher Area. Important information about joining the project and various deadlines can be found in the Project Information section of the Web site.

Come Grow with Us
Grades: K-3
Ongoing? Yes
Come Grow with Us focuses on the life cycle of plants and compares growth data in various environments. Students germinate seeds, record the plant growth over eight weeks, and graph the data. Students are also asked to keep a journal and photographs of their plant growing process. Students then share their data, observations, and pictures at the project’s Web site. The site also provides a list of activities and extension activities, as well as a Teacher’s Page with procedures for preparing the seeds for germination, worksheets, and templates for data recording. A links to additional resources and to the relationship of the project to science and technology standards are provided.

Down the Drain
Grades: 4-8 (but can be modified for high school students)
Ongoing? Yes
Water, water, everywhere! Down the Drain asks students compare their own water usage to that of people in other parts of the world. They spend a week collecting information from household members and classmates to determine the average amount of water used by one person – after completing data collection, students predict what they will find and then test these hypotheses by analyzing the data. Students submit data online for analysis and can periodically download the results as spreadsheets. Classes have the option of posting student work online. Rich resources for teachers include lesson plans (the charts are really handy!), links with water-related information and online conversion calculators, and the online help page which contains links to several “ask an expert” sites dealing with science, environment, and water.

Fit For Life Nutritional Survey Project
Grades: 2-8?
Ongoing? Yes
Are your students eating the recommended number of servings of fruits and vegetables? Do they even have an idea of what they ARE eating? This project will help them figure that out for themselves. Using an online survey form, students track and calculate their average intake for each of the five food groups for five days. Then they calculate their class average, post it to the Web site and view their results as compared to past averages over the last several years. The goal of the project is to increase student awareness of the kinds of foods they eat.

Global Grocery List Project 
Grades: K-12
Ongoing? Yes
As the title implies, this project invites youngsters from all over to report prices on various grocery store items. Students can then compare their data with that of people in other areas, and even in other years. (The project is in its 16th year!) This is a well-conceived project that helps students better see their role in the real world.

The Global Water Sampling Project
Grades:  9-12
Ongoing?  Yes
In these days of abounding pollution, water quality has become a serious concern.  The Global Water Sampling Project, created by the Center for Improved Engineering and Science Education (CIESE), gives high school students the opportunity to sample water in their area, analyze its quality based on physical characteristics and chemical substances, and then share and compare this data with other students’ data from around the world.  It is also gives them an opportunity to hypothesize about any trends in water quality.  The project runs every fall and spring with specific guidelines available on the Web site.  Additional classroom activities are available as is a list of national science standards met by the project.  There is also an Online Experts section that allows students to gain further knowledge through contact with an expert in the field.

Seasonal Changes Through Our Eyes and Yours
Grades: K-5
Ongoing? Yes
In this project students observe the changes in a specific tree, clothing worn, temperature, and the sunrise and sunset during the fall, winter, and spring seasons. There are specific lesson plans to follow for each of the observations at each of the different observation times. The students then record their observations on the data gathering form provided at the Web site. Using the Web site, students share their data with other participating schools. Using the data posted, students are able to analyze, compare, and draw conclusions about their environment in relation to environments around the country. Extension activities and standards alignment are provided as well.

Tooth Tally Project
Grades: 1
Ongoing? Yes
This project has more loose teeth than a heavyweight championship! As students in participating first grade classes lose their baby teeth, they pin paper teeth to their class tooth tally board. At the end of each month, the teacher sends the total to the project's Web site. where it is posted online for comparison with other classes in their group. Highlights include children's descriptions of the tooth fairy, links to several classes' tooth tally websites, and suggestions provided by ! teachers on ways to incorporate this project into existing curriculum.
