Frozen water is 9% lighter than regular water. That is the reason ice floats.
Educational resources are a powerful tool. Boston Water and Sewer Commission (BWSC) has designed this section for young people, parents and teachers. It contains lists of resources that can be downloaded. It also provides information on National Drinking Water Week which is celebrated every year during the first full week of May.
BWSC maintains a small library which contains a suggested reading list for both students and adults.
Available to Boston school teachers, BWSC has a number of activity books on a variety of different water and wastewater issues for all ages/grades. Teachers can request a free sample.
Celebrated the first full week in May, this is an exciting event that is held throughout the United States. Water distribution utilities, such as BWSC, and environmental groups across the country use the National Drinking Water Week to reach out to young people to create awareness of and involvement in water issues. The major activity for children is the Annual Poster Contest.
In preparation for National Drinking Water Week, the BWSC in conjunction with the Massachusetts Water Resources Authority (MWRA) encourages all Boston students (K through 8) to enter the Annual Poster Contest. The topic is different every year, however, most often the topic focuses on the connection between the natural environment and water resources.
