In this activity, students are asked to decide which would melt faster: a large block of ice or the same block cut into three cubes. The activity is one of 80 mathematical challenges featured on the FigureThis! web site. The animated introduction to this activity notes that surface area and volume are important to the work of architects, interior designers, and chemists. Students are encouraged to compare the surface area of the ice cubes to the larger block. The complete solution demonstrates how to calculate the surface area of the cubes as well as the large block of ice. Related questions ask students to determine surface area and volume for irregular shapes and to ascertain the relationship between surface area and volume in different situations. Answers to all questions and suggestions for other resources are included. Copyright 2005 Eisenhower National Clearinghouse

Title	Middle School Portal: Math and Science Pathways (MSP2)
Link	http://msteacher2.org/
Description	The Middle School Portal 2: Math and Science Pathways (MSP2) supports middle grades educators with high-quality, standards-based resources and promotes collaboration and knowledge-sharing among its users. Educators use MSP2 to increase content knowledge in science, mathematics, and appropriate pedagogy for youth ages 10 to 15. MSP2 employs social networking and digital tools to foster dynamic experiences that promote creation, modification, and sharing of resources, facilitate professional development, and support the integration of technology into practice. MSP2 is a project of the Ohio State University College of Education and Human Ecology, National Middle School Association, and Education Development Center, Inc., and is funded by the National Science Foundation. The partners integrate resources, tools, and services across projects, and support multiple methods of resource discovery to meet the needs of this audience.
