Compare results to predictions and write yes or no with comments. Continue adding small amounts of water to each glass, recording the amounts, until all have reached saturation. Note the following on a cheek sheet. Materials placed in glass in the correct order. Quiet voices, cooperation.
Students orally describe an aquifer.
Using their mini-aquifer, each group identifies the saturation zone and water table. Each of these could be assigned a point value for scoring. Locate cities or counties over these. Compare water usage in one or two western counties with eastern ones. Educational Series 10.
