Design Lab Experiment: How would an increase in the atomic radii of the metals in period 4 affect the time it takes for a metal to react with HCl. Hypothesis: If Hydrochloric Acid is dropped on all of the metals in period 4‚ then the elements with the largest atomic radii will react faster with Hydrochloric Acid because atoms with bigger atomic radii are

Lab 3. Dc circuits and Ohm’s law of measurments Helina Wolfe Tannaz Farnoudi and Najah Rouse Physics 246-205 Professor Joe Renaud 09/23/13 Word count:1453 Abstract: The aim of this experiment was to understand the relationship between the variables of Ohm’s law and how they are part of an operation of an electric circuit. Introduction: This experiment was done in two parts. The first part consisted of understanding how to determine the current‚ voltage and resistance

Physics Lab Report#3 “Determining the period of a pendulum” Name: Fei Huo Date performed: October 1st‚ 2014 Period 5 Teacher: Mr. Glasel Purpose: The Purpose of this Lab was so that my classmates and I can examine what kind of factors affect the period of a pendulum. Introduction: In a simple form‚ the pendulum is a weight hung from a long string that Galileo discovered that it can be used to track the passage of time very accurately around 400 years ago. In this

Impulse and Momentum Lab Part I: As the first lab of the Physics 2 curriculum‚ our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. In this lab activity‚ we used a lab cart on a flat track to compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track‚ a timer

Kathryn Marchessault Physics Lab LR Tuesday 8-9:55 Due 02/26/15 Experiment #1 Free Fall Experiment Abstract In this experiment we studied the motion of an object in free fall‚ that is an object being dropped from a certain height to Earth’s surface. In this experiment we tested the idea that no matter what the size‚ shape‚ color‚ etc. of the object if it would still experience the same constant acceleration throughout its fall (short distance). The constant downward acceleration it experiences

Lab II‚ Problem 3: Projectile Motion and Velocity Oct. 06‚ 2013 Physics 1301W‚ Professor: Hanany‚ TA: Vladimir Abstract A ball is tossed obliquely. The vectors of position and velocity are measured. The acceleration is calculated. Introduction A toy company is now making an instructional videotape on how to predict the position. Therefore‚ in order to make the prediction accurate‚ how the horizontal and vertical components of a ball’s position as it flies through the air should

Design Research question: This should be a clear focused question that says exactly what you are investigating. It shouldn’t be too long and it must include the dependent and independent variables. Eg. What is the effect of pH on the activity rate of salivary amylase? Dependent variable: activity rate Independent variable: pH Hypothesis: This is a paragraph or two where you explain your research question. You are going to say something like: "Salivary Amylase is a an enzyme that digests
