Activities in which students build their own simulations of fossils, using seashells, chicken bones, toy dinosaurs, or leaves as models and plaster of paris, sand, mud, clay, or a mixture of gravel and clay as a matrix are presented. Curriculum extensions are included. (KR)

The use of simulation is discussed, including its effectiveness in generating environmental awareness and an environmental ethic in the student. Two simulation activities are described. (RE)

Presents a Project WET water education activity. Students simulate the movement of water within the water cycle by role-playing a water molecule's movements. Students learn the states of water as it moves through the water cycle. (LZ)

Describes an activity for use with a chapter on dinosaurs, prehistoric life, or digestion in which children make simulated dinosaur stomachs to gain hands-on experience about the theory of gastroliths, or stomach stones. Presents teacher information about the digestive processes in birds and dinosaurs. Discusses materials needed, objectives,…

Program listing for a computer game on kinematics is provided. Documentation for the listing (in Microsoft BASIC) and rationale for using computer games in the classroom are also provided. (JN)

Described is an environmental awareness simulation game involving the life function of food getting. Instructions, charts, task sheets and questions are included for each segment of the game. (DS)

Explains the arrangement of materials in a classroom to simulate land or weather conditions. On each desk in the room pertinent bits of information are placed. Students gather bits of information and synthesize material into an overall map of the area. (CP)

Presents methods for analyzing soil and water samples in this classroom. Includes a classroom diagram, a listing of suggested materials, and the procedures for a classroom simulated pond. Relates classroom activities to work at a natural pond. (MA)

Describes how a class of 32 students can simulate the beating of a human heart by having the students themselves act out the various parts of the heart. (HM)

Presents activities to familiarize junior high school students with the processes behind and reasons for volcanism, which is generally a planet's way of releasing excessive internal heat and pressure. Students participate in the creation of four important volcano-related simulations: a lava flow, a shield volcano, a cinder-cone volcano, and a…

Presents a Project WET water education activity. Through a game of tag that simulates the effects of environmental stressors on macroinvertebrate populations, students relate the concept of biodiversity to the health of an ecosystem. (LZ)

Describes a simulation of chemical reactions to help students understand factors that affect the rates of chemical reactions. (PR)
