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

AP Biology Dissolved Oxygen and Aquatic Primary Productivity Purpose: To measure and analyze the primary productivity of natural waters of laboratory cultures using screens to simulate the decrease of light with increasing depth. Background: Dissolved oxygen (DO) is how oxygen is measured. Oxygen is required in cellular respiration‚ so it is very important for aquatic life. When more oxygen is consumed than is produced‚ dissolved oxygen levels decline and some animals could die if they do not

question in the end that was he the good guy or the bad guy? The main setting is the Australian bush (outback) because the chorus keeps on repeating after each stanza: “Then‚ come all my hearties‚ we’ll range the mountain sides‚ Together we will plunger‚ together we will ride‚ We’ll scour along valleys and gallop o’er plains‚ we scorn to live in slavery bowed down in iron chains.
