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,…

Explains the capture-recapture method which is used to estimate population size by researchers. Uses a computer simulation game to teach students the capture-recapture method of population size estimation. (Contains 24 references.) (Author/YDS)

Describes five activities designed to help students recognize and appreciate the factors directly involved in the process of fossilization. (JR)

Describes an instructional unit designed to increase student awareness of environmental pollution and the difficulties involved in correcting the situation. Seventh grade science students collected local water samples, tested them, and reported significant pollution to state and federal authorities. Simulation game Dirty Water'' increased student…

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)

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)

Describes a classroom activity designed to interest and motivate students in science. By comparing scientific experimentation to the processes employed in planning, playing, and analyzing the results of a football match, students become more aware of the similarity between activities in their lives and in science.
