The Displacement Reactions Purpose: to see how displacement reaction works with different chemicals and what chemical has more reactivity series then other Hypothesis: Iron + Copper Sulfate: Iron will displace copper because it is more reactive and it is going to end up as Iron Sulphide + Copper Copper + Silver Nitrate: Copper will displace Silver because it is more reactive and it is going to end up as Copper Nitride + Magnesium + Copper oxide: Magnesium will displace Copper because it

How is the room organized? (A quick crafted diagram is helpful) I observed a 3rd grade classroom. The classroom is bright and cheerful. Looking around the room and knowing the teacher‚ I could tell that the room theme is frogs‚ which was very cute. The first thing that I saw was the Character Trait posters on the wall. The front of the room had a blackboard and on either side are bulletin boards. One bulletin board has the classroom rules and consequences and the class jobs. The other bulletin

A Simple Exploration of Bounded Rationality by Susan Fisk “Psychological theories of intuitive thinking cannot match the elegance and precision of formal normative models of belief and choice‚ but this is just another way of saying that rational models are psychologically unrealistic.” -Daniel Kahneman Sit back and imagine that the United States is preparing for the outbreak of an unusual disease‚ which is expected to kill 600 people. Two alternative programs to combat the disease have

1. Introduction: This investigation will show the effect of temperature on the rate of reaction. The Berocca tablet was reacted with hot water (47oC) and then with cold water (20oC). In the hypothesis‚ it was predicted that the temperature will be inverse proportional to the time Berocca tablet reacts with water to produce 50ml of carbon dioxide gas. Through the result table‚ we can see that the hypothesis is supported and it was correct. In the conclusion‚ it was shown that the temperature has the
