1 birth and simulation activities, factors that affect the look of the water.The purpose for1. try to observe and describe the characteristics of the water signs, resulting from the scenario.2. observe the drawing style and the model water occurs from the beginning until the downstream water.3. a description of the direction of flow of the water. The size and shape of water The speed of the water signs, including students, erosion. The blows and the accumulation of sand that occurred shelve scenarios from.The question before the trial activities 1.1What's different is that the (size of the sediment).The same thing is (the height of the sediment).Activity 1.1 What is different (the height of the sediment).The same thing is (the size of the sediment).Save the result table.Experimental activities. The result of the experiment. Drawing from observation.The same water on piles of sludge that has a different size. Pour water evenly on a pile of sediments of the same type but with different height. Spray water on the sandbox The question at the end of trial.1. slit the water caused by a pile of gravel and sand that has a height equal. Look different? ?Response of water caused by the sand piles the Groove above the sand erosion is more than a trace of Nam burst from fast kongok. 2. signs of water caused by the sand piles with different height. Look different? ?Response of water caused by the sand piles the Groove, the higher will be the deep erosion over. 3. from the activities which factors affect water occurs, Groove looks different.Respond to the strength, speed, and quantity of water. The type of sludge height of sediment. สรุปผลการทดลอง......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................2 the activity occurs and simulate how groundwater catchment sources.The purpose for Experiment and modelling groundwater catchment sources.The question before the trial.Chandin's ranking in the experiment there, however (putting the clay bottom alternating with layers of sand).Trial scheduleExperimental activities. The observed results.Carpet water into plastic boxes. The question at the end of trial.1. size of sediments and clay with varying size?Reply to sandy sediments are larger than clay.2. when the water goes to the mat, plastic box, water level in the sand and in the coffee fool has changed?Sand and water level response in the coffee tube will fade. 3. the water source to be planted in what kinds of sludge layer. How many layers, and it looks like sediment.Reply to ooze water and cumulation in sand 2 layer, each layer will be flanked by chandin sticky on either side or both sides and the sediments of sand and sediment characteristics with granular size ruan equally. Summary trial..................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................Activity 3: characteristics of sediments affect the groundwater catchment organization?The purpose forIdentify and describe trial characteristics of sediments, which can be a good catchment.The question before the trial.Container with 1 leaf 2 is there anything different. There is a sludge that is equal in size, so there is a gap between the more granular sludge. The table, save the results of the experiment.Experimental activities. The observed results.Equal-sized containers that enter the gravel Coarse sand, gravel, mixed stoneware insert The question at the end of trial.Silt catchment is the most resemble?Reply to sediments that are equally so there is a gap between the more granular sludge. สรุปผลการทดลอง...................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
