Inventions of the Renaissance Clocks The first mechanical clock was invented in the early 1300’s. With this invention time began to be measured in hours (24 hours equaling a day). Galileo‚ an Italian scientist‚ discovered the pendulum in 1581. The pendulum greatly improved the constant movement of the hands or bell of a clock. The average error with the pendulum varied only by seconds each day. Before this the error was from 10 to 15 minutes a day. During the 1600’s the metallic gear‚ or toothed

Scientific Investigation Part I: Scenarios Scenario 2 Lizzie loves to stargaze at night. She has noticed that the moon appears to change shape over the course of the month‚ and she wants to investigate why this happens. She hypothesizes that the relationship of the sun‚ Earth‚ and moon creates shadows on the moon. She sets up an experiment with a light

ARTWORK FOCUS: analysing the artwork with a focus on the cultural and structural frame. Analysing an artwork through the lens of a cultural frame reveals how the conditions of place and time‚ and the values and beliefs of a society are reflected in the artwork. To adopt the lens of the cultural frame‚ ask yourself: What is the purpose of the artwork? Why does it look the way it does? What values and beliefs of society are embodied in the artwork? What conditions of place and time does the

2-8 Refraction and polarization of light 5. Experiment Results A. Linearity of light 1. The light beam does go straight when we tested on the angle board. 2. As the source of light beam was getting farther away from the slit‚ the beam becomes narrower and shorter in addition to fading. This is because light particles escape more when they travel to go through the slit. B. Law of reflection Angle of incidence is the angle formed by a ray incident on a surface

I chose to write about natural disasters‚ and more specifically flooding. The disaster flooding that is going on in Colorado right now is not only heart breaking but has science written all over it. From the sudden change in climate to human influence there are many ways science is involved in floods. Looking up the difference in scientific news and daily news I have found that scientific news talks more directly to how natural disasters effect the world. Going through the steps in the scientific

PLANNING: - Title: - An Experiment to investigate the lateral displacement of a ray of light through a rectangular block of a transparent material. Aim: - To investigate the lateral displacement for different angles and how the displacement depends on the angle of incidence when a ray of light enters the Perspex block. Scientific Background: - Refraction occurs when the speed changes when the lights travels from one medium to another medium. If the light travels from a medium to a denser medium

Amends: Author is a feminist who believed that women went unnoticed and their left to make amends for other peoples actions. The very title amends means to compensate or make up for a wrongdoing. In this particular poem it’s the moon making amends for the faults in the world. The very first line is from Merchant of Venice‚ act 5‚ helps set the scene‚ automatically linking the poem with the moon. “Cold” atmosphere‚ suggests night-time‚ white star further suggests night-time. “Another exploding”
