1 birth and simulation activities, factors that affect the characteristics of the water stream
purpose 1. Try to observe and describe the characteristics of the water signs, resulting from the scenario.
2. Observed and simulated water feature drawing that occurs from upstream to downstream
3. Description of the flow direction of water. The size and shape of the brook The speed of the water signs, including students, water erosion. The blows and the accumulation of sand that occurred shelve scenarios from
question prior to trial activity 1.1
.What's different is that (the size of the sediment) is the same thing
(height of the sludge)
activities 1.1 What is different (the height of the sludge) is the same thing
(size of sediments)
result log table.Experimental activities. The result of the experiment. The paintings have to observe the same pile pouring water on
sediments with different sizes.
Same pouring water on piles of sediments of the same type but of different height.
Water spray on the Sandpit
question at the end of the experiment of
1. Signs of water, sand and gravel from the pile with the same height. Looks different? However, the replies from Groove
piles of sand, sand erosion is higher than the water that comes out from the Groove fast kongok.
2. Signs of water caused by the sand piles with different height. Looks different? However, the replies from Groove
piles of sand, the higher will be the deep erosion.
3. What are the factors from the activity resulted in water occurs, Groove looks different
answer. Strength, speed, and quantity of water. The type of sediment thickness of sediment

2 birth and simulation activities simulate how groundwater catchment sources
purpose. Experimentation and modelling groundwater catchment sources.
question prior to trial
.Chandin's ranking in the experiment is, however (putting the clay bottom alternating with layers of sand)
trial trial activity table. The results observed water into carpet
plastic box
a question at the end of the experiment of
1. Size of sediments and clay with varying size?
answer. Sediment is larger than sand clay
2. When the water in plastic boxes, carpet, water levels on the sand and in the coffee fool has changed?
.Answer: water in the sand and in the coffee tubes will fade.
3. water source to be planted in what kind of sludge layer. How many layers and sediments, it looks like
.Meet the water accumulated in the ooze and sand layer of 2 floors, each floor is flanked by chandin sticky on either side or both sides and 2 sediments of sand and silt grains ruan looks equally sized.

3 activity characteristics of sediments affect the groundwater catchment account?
purpose.Try and describe the characteristics of the sludge can be good catchment
question prior to trial that ended up on the 1
2, what is different. Sediments that are equally so there is a gap between the sediment grains.
Experimental results log table
trial activity. The result of observations
container put equal-sized pebbles.
Coarse gravel or sand mix holders containers
Frequently asked questions at the end of the experiment, which is sediment catchment
.
looks like.The sludge is answered equally, so there is a gap between the sediment grains.
