Show In one corner of the classroom make a conservation corner. This " corner" can be a place to exhibit many things that relate to the wise use of soil, water, grassland, woodland, wildlife, and mineral resources. You will need a long table. Here are some things that you can collect and keep on the table: Different kinds of soil- silt, clay, sand. Put them in small glass jars and label them. Different kinds of rocks from which soil is made- limestone, sandstone, shale, marble, granite, and as many others as you can find. Label each. A good way to keep rocks is to embed them in a 1- inch layer of plaster poured into a cardboard box. After the plaster hardens, remove the box. Samples of different kinds of fertilizers. Keep in small glass jars and label. Seeds of various crops that have soil conservation uses such as grasses, clovers, alfalfa. Label each. Leaves, bark, twigs, and fruit of trees, shrubs, and vines that grow in your locality. Learn how to collect leaves and to press and mount them for display. To make live things more alive and dead things " live," make your displays and collections tell a Container board accounts for about a fourth of our paper and board use. Newsprint accounts for an additional 17 percent of paper use. The rest is used in a myriad of forms- writing paper; sanitary cartons for prunes, cereals, butter, ice cream; paper cups, plates, disposable napkins, towels, handkerchiefs; wrapping paper for groceries, meats, dry goods. Scientists and engineers at the Forest Products Laboratory are carrying on a specialized research into the uses of wood. They are developing more efficient use of timber in large structures by improving joints and fastenings necessary in bridge, arched hall, and hanger construction. We must also grow trees for soil and water conservation. There are millions of acres of land in the United States that are not suited to cultivation but that can grow trees. If this land were put into crops, the soil would wash away. The result would be floods, streams choked with silt, reservoirs filled with mud, or crop failure caused by lack of irrigation water. Also mountain streams would dry up, springs would cease to flow, and many forms of wildlife that live in the forests would disappear. Steep land, rocky land, shallow soil, some wetland, some dryland, and many other land and soil conditions require the growing of trees. If we had no use for trees other than to protect land not suited to grass or cultivated crops, that would be enough. story. Collecting leaves, insects, and rocks is much o more interesting if the leaves are organized into e smaller, more significant displays of leaf types, d and if the rock exhibits show how mountains are formed, what kind of soil they make, and what e stones are used for building materials. : A label on an object or exhibit can capture t interest, create curiosity, or make the reader think. The labels should be short, informal, and s chatty. Make new labels occasionally to point i, out new facts of interest. 1. There may not be room for all the displays to be shown at once. But changing the scene is d good and is more interesting anyway. [. Set aside a shelf labeled " What is it?" Put p unidentified finds here until someone identifies them. You can also put objects here that you want to draw to the students' attention. As a > 1 special event put a number of objects on the shelf and give points for identification. 5, Make a conservation scrapbook by collecting v pictures from newspapers, magazines, and other r sources showing erosion and how it can be controlled. Relate soil and water conservation to s plants, birds, and animals. Make your scrapbook tell a story by organizing XXL Make a Conservation Corner 26 |
