Parachute experiment Aim: The aim was to find the effect of holes on a parachute‚ varying their size and number. Hypothesis: 1. By increasing the number of holes‚ the time it will take to the parachute to reach the ground will be longer and its flight will be more balanced. 2. By increasing the size of the hole on the parachute‚ the time it will take to the parachute to reach the ground will be shorter and its flight will be less balanced. Apparatus: - garbage bag (squared shape

Environmental Science The Scientific Method Amber Steadham October 31‚ 2012 Abstract: We conducted several experiments using the Scientific Method. We made observations‚ recorded them and used our observations to propose a hypothesis. The experiments included chemical and physical reactions dealing with torn news paper‚ appearance of rock salt crystals‚ the appearance of sand‚ oil and water on plastic‚ and making iodine in water and mineral oil. We found that all these included four physical

Salt from green beans Name: Ashni Couprie and Dennise Susanto Class: 5c Introduction From previous experiments we ’ve learned that salt is extracted from green beans. To be more specific: salt is extracted from when the beans are cooked in water in which salt has been dissolved. This experiment is based upon the osmoses theory. According to this theory the cell walls of the green beans are what we call a semi permeable membrane. This membrane only lets water through and not the substance

Truss Bridge Physics 141 Robin Hoffmeister There is many reason that we need bridges in every day of our life‚ from sufficient means to pass over a roadway‚ waterway‚ railway‚ or other structure. You don’t even think about them because it takes no effort to get over them and they are just there for your use. So if you don’t think of them for everyday use I highly doubt that you would think of the physics that is involved in putting one together or the kind of force the bridge can actually

The Bobo Experiment was performed in 1961 by Albert Bandura to try and prove that people‚ especially children‚ learn their social skills and behaviors from copying or mimicking adults in their lives rather than through heredity genes. Bandura wanted to show‚ by using aggressive and non-aggressive adult-actors‚ that a child would be apt to replicate and learn from the behavior of a trusted adult (Shuttleworth‚ M. 2008). These issues have been present for many years‚ even before the media used these

so deeply ingrained and powerful that it cancels out a person’s ability to behave morally‚ ethically‚ or even sympathetically. In 1963 Milgram carried out an experiment. He hypothesized that individuals who would never intentionally cause someone physical harm would do so if ordered by a powerful authority figure. To carry out the experiment‚ Milgram designed a shock generator- a large electronic device with 30 switches labeled with voltage levels from 30 volts increasing at 15-volt intervals to

The Bandura et al experiment in 1961 conducted research into how we can transmit aggression through imitating aggressive models. 36 boys and 36 girls aged between 37 and 69 months were subject to this experiment. There were 3 conditions‚ the control group‚ the group exposed to the aggressive model and the group exposed to the passive model. In the standard condition‚ a child was settled in a corner with a small table and chair‚ potato prints and picture stickers. An adult model was then escorted
