Research Activity Constructivism and Student Misconceptions: Why Every Teacher Needs to Know About Them The article I chose to do this research activity on was "Constructivism and Student Misconceptions: Why Every Teacher Needs to Know About Them" by Audrey Sewell (Appendix A). I believe this article addresses a key idea that all teachers should be aware of‚ student misconceptions. For this paper I will start by summarizing the key ideas‚ then I will go on to discuss how they relate to the

Above the pendulum is an hourglass. The clock is a reference to the passing of time. The narrator realizes that the pendulum is razor sharp and is a scythe‚ a long sharp tool used by farmers to cut large amounts of crops or grass at one time. However‚ in this short story it is being used the kill the narrator of the story instead of cutting corn. A combination of the clock and the falling pendulum or scythe represent the Grimm Reeper.

classic example of this intra-conversion is a pendulum. Throughout a swing of a pendulum the total amount of energy (potential plus kinetic) is constant. When the pendulum reaches its highest point at the end of the movement‚ all its energy becomes potential energy. As it begins‚ a downward swing gains kinetic energy and loses potential energy. At the lowest point of its trajectory all its energy is converted into kinetic energy. As its proceeds to swing to its highest point it loses kinetic energy

Acceleration Due to Gravity with a Simple Pendulum Quintin T. Nethercott and M. Evelynn Walton Department of Physics‚ University of Utah‚ Salt Lake City‚ 84112‚ UT‚ USA (Dated: March 6‚ 2013) Using a simple pendulum the acceleration due to gravity in Salt Lake City‚ Utah‚ USA was found to be (9.8 +/- .1) m/s2 . The model was constructed with the square of the period of oscillations in the small angle approximation being proportional to the length of the pendulum. The model was supported by the data

fire a 5g plastic ball straight up in the air. Find: a) the launch speed b) the maximum height to which the ball rises 2) A pendulum with a mass of 50g on it at a height of 30cm is allowed to swing. At the bottom of its swing it strikes a horizontal spring that compresses 5cm in stopping the pendulum. What is: a) the spring constant? b) the speed of the pendulum bob when the spring is only compressed by 3cm? 3) A ball of coefficient of restitution 0.86 is dropped from a 20m high balcony

Topic: Millikan Oil-Drop Experiment The Millikan Oil-Drop experiment was the first experiment to determine the charge of an electron. In 1909‚ Robert Millikan ultimately came up with a way to determine this charge through finding the minute electric charge on a droplet from an oil mist. Basically‚ Millikan started with an enclosed chamber that had two flat plates inside‚ one with a positive charge and one with a negative charge. The portion is split up by the positively charged plate so at the beginning
