Our group has chosen two key concept, they are perspective and causation. We chosen this two concept because we cant to find the cause of the landslide and the way of peoples mind about landslide. That's why we went to Mt. Pancar one month ago to found some information from the villager that leaves there. We got quite many information from the villager. We also found our key of our field trip which is the causation. We found out the affect after the landslide happens and also the process of the landslide when happening. We also found out the perspective of the villager there about when the landslide were happen. After we went to Mt. Pancar, with our performances and experiment. We had make two posters. So now we are moving on our experiment. We tried to do the under water landslide. But there is a problem..... The land under the water won't move. So now we're trying to fine the possible solution to make it slides down the water.
