is to calculate the average human reaction time for a simple task. Hypothesis If the activity is repeated a number of times‚ then the reaction time will decrease‚ therefore the slower the reaction time‚ the further the ruler will fall. Variables - which variables are you going to: Change? (Independent Variable) The Independent Variable in this Investigation is the reaction time. Measure? (Dependent variable) The Dependent Variable in this Investigation is how far the ruler falls. Keep the same

BOILING POINTS AND MELTING POINTS PART 2 Name: Grethel Zegarra Date of Lab: October 26‚ 2010 Date lab is due: November 2‚ 2010 HYPOTHESIS The boiling point in degrees Celsius will increase as the number of carbon atoms increase. The melting point of the unknown will indicate its mixed substances. The boiling point will increase as a result of the different branching of the OH‚ the melting point will be affected by the different positioning of the OH on the benzene ring. PURPOSE To introduce

An impressive story is about the sad fate of widows in India during the past century‚ before Ghadi’s ideas started changing India’s traditions. First of all‚ water is also the story of a people trapped in a hidebound culture that values tradition above basic rights and dignity for women. I was unaware of this issue‚ but this movie harshly questions a religion that imposed such a level of degradation upon women

Jared Choy Mr. Dahlhausen Period 6 17 November 2014 Does Age affect Reaction Time? When a person sees a health care provider and the doctor hits the person’s knee with a rubber mallet‚ the person’s leg kicks up on its own. This happens because when the doctor hits your kneecap‚ the tendon under it gets stretched‚ which in turn will send a signal to an awaiting motor neuron so it can command the muscle to contract. Let’s take for example the reflex arc. A reflex is the involuntary movement of the

The Concentration Camp sort of opened my eyes to my inner reactions towards death and my much deeper ractions towards suffering. The Holocaust reading further showed me my reactions to death.

‘Kinetics’ is the study of chemical reactions. The speed of a reaction can vary depending on many variables such as the nature of the reactants‚ particle size‚ concentration and temperature. For a chemical reaction to occur‚ there must be a collision between reactants. The reaction rate is slower when the reactants are large and complex molecules because it takes longer for the molecules to combine together creating a chemical reaction. More than 2000 years ago‚ Democritus‚ who was a philosopher
