Purpose: To practice direct and indirect measurement Introduction: Do you think you could measure the average thickness of a sample of M&Ms without directly measuring selected M&Ms? The answer is "yes‚" and in this activity you will make direct and indirect measurements of the thickness of M&Ms. You will compare the results and evaluate the reliability of each method of measurement. Be sure to view the tutorial on the proper use of the vernier caliper. Please re-visit the information on when

Hurricane Katrina was one of the strongest storms to impact the coast of the United States during the last 100 years.

In this critique‚ I will review three posters‚ including two posters from my classmates and one poster made by myself. The poster on the left is “Dear Chili Pepper‚ why are you so hot?” by Ng Lai Yan. The poster in the middle is “A little is enough – Vitamins” and it was made by me. The poster on the right is “Chili Pepper – Fruit of Immortal” by Ching Man (Abby). The poster would be examined by its quality of design‚ science and conclusion. Quality of Design Generally‚ both posters are very beautiful

Experiment 4 Projectile Motion Introduction We examined projectile motion by observing a ball rolling down then leaving the ramp‚ thus becoming a projectile with a horizontal initial velocity. We measured the horizontal initial velocity using the photogate and computer. We measured the horizontal and vertical distances that the projectile traveled from the end of the ramp to when it hit the floor my using a meter stick to measure Experimental Set-Up In our experiment‚ we used the following:

ABSTRACT This document describes the experimental process of developing a non-mechanical hot plate wind and rain sensor. It aims to discuss practical aspects of the necessary hardware to fulfil such a function and different software approaches to controlling such a system. Specifically‚ it discusses an experiment based on 30W hot plates controlled by Labview in an attempt to measure changing wind and rain conditions. It also looks at the data gathered in this instance and calibration
