Children explore the buoyancy of common objects and make boats from a variety of materials, gaining a sense of the relative contribution of the material and its shape in determining whether it will sink or float. They repeat their experiments with salt water and other solutions to see how the type of liquid makes a difference in how things float. Instructional material.
Explore It! is a series of exploratory science experiences for out-of-school programs and elementary school students (ages 8-12), funded by the National Science Foundation and developed by Education Development Center, Inc. Explore It! includes a guide for each project and a special guide for implementing the program. These extended explorations provide an experiential foundation for science concepts associated with basic phenomena and helps develops essential skills for inquiry in the formal context.
Instructional materials only.
