The article describes an activity that can be used to teach students in an Earth science course about things that they can do to reduce their personal impact on the production of municipal solid waste. The activity involves showing students how paper can be easily recycled. It includes the creation of slurry, the addition of texture and color to paper, and the drying of recycled paper. As per the author's experience, the activity can be effective in encouraging students to engage in recycling at home.

The article evaluates a demonstration held for a soil science class to show the role of emergent properties as behavior endemic to dynamic systems. The demonstration involves baskets, one contains balled-up sheets of paper that are defined as quanta of energy or matter while the other is empty, and one volunteer as mover and located within the membrane. Based on the demonstration, it is noted that a system's environment is not static while the amounts and kinds of matter and energy affecting an open system vary around a mean that the system has adapted to. It is believed that students' participation in this dynamic exposes them to the unpredictability of adaptive responses to perturbations.

The article presents information on early childhood learning centers. To create a career-oriented learning center in the class-room, set up three long folding tables in a T or U shape and drape colorful plastic cloths over them. Children tend to gravitate toward tools, so have a variety on hand, such as magnifying glasses, magnets, clipboards, graph paper, rulers, eye droppers, funnels, scoops, etc. Some children also enjoy dressing up, so have swim flippers, hard hats, or a life jacket and other items for those more active students. Some of the career centers set in the classrooms are: Kitchen Chemistry--Use clear containers with numbers and measuring tools to learn the properties of water. Work with gelatin, Popsicles, and pudding. Mix colors with eyedroppers and food dye or finger paint. Experiment with cornstarch and water on a cookie tray to see how a substance can be both a liquid and a solid; Nutrition/Botany--Create a store-front with plastic fruits and vegetables, empty food boxes, and a play cash register with play money.

The article offers information on the creativity of a teacher, who tells a story and asks the students to draw a magic genie and create a magic bouquet.

The teacher also finds some dirty flowers and tries to change the color of the flowers. The teacher becomes very happy with the change of color after washing them in the water. The teacher instructs the students to do several activities including to paint an empty bottle or jug that has a narrow neck fitted with a cork. He further instructs to wrap 4 grams of sodium iodide or potassium iodide in tissue paper. He instructs to prepare the magic bouquet by soaking a bunch of while silk flowers in different solutions including litmus, and phenol red.
