91 differences in sand (e.g., size, color, shape, and composition) by using sand collec tions that may be obtained from various sources, including family and friends. The differences result from the variety of rock sources from which the sand has come, the weathering processes to which the rock has been subjected, and the complete ness of the weathering (i.e., how long the rock has been subjected to weathering). Students should attempt to identify any minerals or rocks that would indicate the kinds

65 all the air is removed from the bottle before tightly capping it and placing it in a freezer. The expansion of water as it freezes will deform the bottle and possibly even split it. 5. c. Students know moving water erodes landforms, reshaping the land by taking it away from some places and depositing it as pebbles, <span class="highlight">sand</span>, silt, and mud in other places (weathering, transport, and deposition). Weathering produces pebbles, <span class="highlight">sand</span>, silt, and mud. Erosion and transportation move the products of

pieces by mechanical and chemical weathering and the removal of rock and soil by erosion. Water is the primary agent in shaping California’s landscape. Surface water flow, glaciers, wind, and ocean waves have all been and continue to be active throughout California and the rest of the world in shaping landscapes. A “stream table” may be used to demonstrate the effectiveness of running water as an erosion agent. Stream tables can be easily made from plastic bins or dishpans filled with <span class="highlight">sand</span> or gravel. The
