Virtual Ambients
	The Field The Field is a configurable virtual space containing a variety of flowers and other plants spread over a terrain consisting of rocky, sandy, and grassy regions. The Field has been used by students in second, fourth, and sixth grades to study such topics as similarity and difference, conditional co-occurrence, linear extrapolation, distribution difference metrics, and positional distributions. About the application 6th grade: conditional co-occurrence (2/2000) 2nd grade: similarity and difference (6/2000) 4th grade: linear extrapolation (11/2000) 6th grade: sampling & populations (3/2001) 6th grade: position-dependent sampling and mapping (5/2001)
	The Bee Dance The Bee Dance is an animated, explorable enactment of the dance which honeybees use to communicate the location of food sources. The Bee Dance has been used by students in third, fourth, and sixth grades to study gesture languages.
	The Ocean The Ocean is an animated, explorable environment consisting of both shallow (coral reef) and deep ocean regions, including flora and fauna. The Ocean will be used in December, 2001, by sixth grade students to study the relationship between depth and pressure, ambient light, salinity, and temperature.
QuickWorlds
	QuickWorlds QuickWorlds are 3-D animated models developed in response to teacher requests, and used by teachers in small-group and whole-class settings. The Heart, one of the first QuickWorlds, was used by fifth-grade students to supplement an activity used by a physical education teacher.
Conceptual Change
	Round Earth The Round Earth project is a multi-year project designed to investigate a strategy for employing 3-D virtual environments to help effect change in young children's conception of the shape of the Earth and the implications surrounding that shape (e.g., the relativity of up and down, circumnavigability, etc.)
