My SRP is determining if the colour of ice affects its melting rate. Ice melts by taking in energy from its surroundings to form heat. This makes the molecules in the ice cube vibrate. As the overall vibration increases‚ the water molecules split from each other turning the ice from a frozen state to a liquid state. Heat can be absorbs in two different ways‚ through direct contact with a hot surface or through radiation of a hot surface nearby. Radiant heat can be contributed by sunlight‚ fires and

The whole month my friends have been continuously asking me to come ice skate with them. I had denied them several times‚ because I felt very uneasy going on a low friction surface on metal skates and was almost sure I would fall flat on my face. Public skate bothered me even more because I knew there would be several people there watching me‚ and potentially getting in the way of my skating. When the group decided to each get out of our comfort zones‚ I realized I should go with my friends this

Floral and faunal record‚ glacial and periglacial process‚ stable isotope and other sediment analyses and sea level record serve to provide climate records that span the geologic award.

have had a lot of memorable moments‚ such as in the year 1993‚ where an advert was released of the polar bears witnessing the northern lights. However‚ there is a high demand for electricity and therefore the world is now changing‚ resulting in the ice caps melting rapidly. If society was not to take immediate action then these adorable furry creatures (who have been the joy of Coca Cola) would soon be extinct. Now that Coca Cola’s lovable‚ marketing icon was in danger‚ it was time for Coca Cola

In the articles "The Anglerfish Ambush Predator of the Deep"‚ by Larry Brown and "Polar Bear"‚ by Shandra Brady I learned how anglerfish and polar bears adapt to their enviornments. Anglerfish live deep in the sea. Polar bears live in the icey cold artic. These are both hard places to adjust to. Anglerfish have fang-like teeth that are angeled inward for efficent prey grabbing. Female anglerfish have a spine that resembles a fisshing pole sticking out of their back called an "illicium" and at the

seen trucks out spreading a mixture of sand and salt on the streets after a snowfall to help deice the road. Do we sometimes dump ice cubes into a drink to help keep cool on a hot summer day? Have we ever watched the ice cubes melt and wondered how we could make them melt more slowly—or even faster? In this science activity we will get to try some different‚ common household substances to try and answer this question: What will help a solid ice cube turn into a liquid puddle the fastest? This basic chemistry project can give we some clues

Aral Sea The Aral Sea use to be the forth-largest saline sea in the world‚ that is until in the 1960s. The former Soviet Union diverted the two rivers that fed the Aral Sea‚ to make water available to the surrounding cotton fields and other crop farming regions in the desert like area. Due to the diversion of the rivers‚ the Aral Sea has begun to evaporate into the Aral Sea we see today. Even though the irrigation of the desert did wonders to the farming industry‚ it has left the Aral Sea a complete

Dead Zones in the Baltic Sea Franki M Abstract Dead zones‚ also known as hypoxic zones‚ are areas in the ocean where oxygen levels have been depleted or are depleting. Hypoxia could be due to natural reasoning‚ but more commonly it is a result of careless and uninformed inhabitants of the coast near that ocean. Farming‚ sewage‚ factories and fishing are all major causes of dead zones. If our oceans continue to lose oxygen‚ we will eventually no longer have marine animals/marine

Analysis of the poem “Sea Fever” by John Masefield The poem is about a person whose intense desire is to return to the sea. The person or the speaker has been to the sea before and the repetition of the line “I must go down to the seas again” in every stanza‚ brings out the speaker’s longing to experience sea life again. The speaker wants only a star to guide his tall ship‚ with the sails moving to the wind thereby wishing for a solitary life‚ with only nature taking control in directing him. “And
