The chromosphere is the layer above the visible photosphere. 2. Solar energy passes through this region on its way out from the centre of the Sun. The temperature of this layer ranges between 6 000 ̊C and 20 000 ̊C. 3.
6. Is it possible to light a candle without touching the flame directly to the wick? Why or why not? Materials • candle • matches • safety goggles • lab handout & pen • ruler • watch glass • 400 mL beaker • CO2 indicator solution (limewater) • 50 mL beaker (for indicator) Procedure My lab partner and I performed a series of experiments to investigate the chemistry of the burning of a candle. The teacher provided the following chemical equation to describe the burning, or combustion, in the candle: Hydrocarbon fuel + O2 ( CO2 + H2O The candle we used was a small, white emergency candle about 3.5 cm tall.
To produce hot water in L.L. Bean’s flagship store, the company recently installed a solar hot water system that will offset almost 11,000 pounds of carbon dioxide emissions every year. Suggest some of the questions the company’s managers might have asked at each level of planning for this
The most logical answer is A. When the earth was just starting to form a big astoride hit earth and a large amount of material flew off to form the moon. 3. Sunlight is created from_______ a. Sun light Bulbs b. Thomas Edison c. Yo Moma d. Energy from Nuclear Fusion i. D. Sunlight is the energy that is released when a nuclear reaction causes hydrogen to form in to helium 4.
Spectra can tell us what makes up a star just by analyzing it. The rainbow isn’t the only thing that makes up the star spectra. If you had the ability to look into the light that comes after the color red, you will encounter the infrared light (it is the heat felt on the skin) which eventually merges into the radio section of the spectrum. On the other side of the rainbow, next to violet is a small portion called the ultra violet, which gives us sunburns and tans. You would then find the section of x-ray radiation then the deadly gamma rays.

Sunspots and Flares Our Sun, the 5-billion-year-old star that sustains life here on Earth, powers photosynthesis in green plants and is ultimately the source of all food and fossil fuel. The connection and interaction between the Sun and Earth drive the seasons, currents in the oceans, weather and climate. With a core reaching a fiery 16 million degrees Kelvin (nearly 29 million degrees Fahrenheit), the Sun's surface temperature is so hot that no solid or liquid can exist there. As early as the fifth century B.C., the Chinese reported having observed dark spots on the sun. In 1960, Galileo Galilei of Italy, Johannes Fabricius of Holland, Christopher Scheiner of Germany, and Thomas Harriott of Englandeach independently
Answer = Experiment 2: Solar Energy Table 2: Solar Energy Experiment Results | Environmental Descriptor/Variable | Observations(Each should be compared against direct subnlight) | Weather of the Day | | Motor speed in direct sunlight | | Motor speed at 45 degree angle | | Motor speed under reflectors | | Motor speed with 25% shaded | | Motor speed with 50% shaded | | Motor speed with 75% shaded | | Motor speed under red filtration | | Motor speed under blue filtration | | Motor speed under green filtration | | Motor speed under yellow filtration | | Post-Lab Questions 1. Develop hypotheses predicting the efficiency of solar energy from direct sunlight against the 4 variables tested? Direct vs indirect hypothesis = Direct vs reflected hypothesis = Direct vs shaded hypothesis = Direct vs filtered hypothesis = 2. Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1? Explain how you

“The Greeks believe that fire was given to common humans as a gift by one of their gods Prometheus. The Romans worshipped a goddess, Vesta, who was the protector of the hearth fire, who taught them how to respect fire and its impacts.”(Coleman, pg 6) The first recorded fire pump was created by Hero of Alexandria, a Roman leader. His invention was based on a syringe type design that squirted water when the plunger was pushed down. The first recorded organized fire department was put into effect by the Roman Empire to protect their capital in 22 B. C. After a major fire occurred in Rome in A.D. 6 a permanent fire brigade called the “”Cohortes Vigilum” or Vigiles was established. They would walk the streets at night and look for possible fire hazards, arsons, or possible fires.
