HEAT AND EVAPORATION PROBLEM: Does more heat make water evaporate faster. To test this I observed how the heat affected the evporation rate when water is placed under DIFFERENT WATTS LIGHT BULBS.i decided to do this expierment because I noticed how the water in my pond evaporates because of the sun every week we have to put water in the pond with our water hose. HYPOTHESIS: MY HOPTHESIS WAS THAT THE 75 WATT BULB would evaporate the water faster.all substances have molecules those molecules

photosynthesis in Ivy disks Background: All plants are autotrophs meaning they create their own food from inorganic chemicals in their surrounding. In the case of food‚ plants use CO2 to create glucose. In addition to the inorganic chemicals‚ plants use sunlight to create their glucose because the photosynthesis reaction is endothermic. The rate of this reaction‚ in turn‚ can be measures. And this lab uses oxygen which is created as a result of the photosynthesis reaction. Since

to investigate the effects of light and gravity on the growth of sunflower seeds. Background Info: Tropism is directional movement in response to a directional stimulus eg light or gravity. Plants are not able to relocate if they happen to start growing where conditions are nor perfect but they can alter their growth towards more favorable conditions. Plants respond to light (phototropism) where the stems grow towards the light and the roots grow away from the light. They also respond to

The Northern lights‚ or Aurora Borealis‚ are one of the world’s most amazing phenomenons. The lights are the result of collisions between gaseous particles in Earth’s atmosphere with charged particles from the sun. Free electrons and protons are thrown from the sun’s atmosphere by the rotation of the sun. The charged particles are are largely deflected by the earth’s magnetic field‚ but at the north and south poles‚ the magnetic field is weaker‚ allowing some charged particles to collide with gas

Factors of Channel Intensity Decisions There are eight factors for channel intensity decisions and the first is channel competition to prevent complacency in this a manufacturer has to place its brand or product in different stores. This helps the business to expand its profits‚ and keeps them in competition with other brands. The book tells us how weaker brands may do this by contracting with large retailers such as Wal-Mart in order for their product to be show cased; but this may not always be

Little lights shine their way down the rugged winding path. Foot steps trudge in front and behind staying close together. Dodging thorns and burs left and right. Ouch!—Every time. Quiet laughs fill the silence as we continue on. Our trek ascends us up a treacherous slope and through a cow pasture carpeted with mines and under a barbed wire fence and down a mile long tractor path that feels like an eternity all with our bags and rifles being persuaded down by gravity. Finally‚ we make it to where

Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of
