The Effect of Different Colored Light on Plant Growth Results I measured each plant on days 7‚ 9‚ 11‚ 13‚ 15‚ 20‚ and 32‚ after planting. The plants under the green cellophane grew the most in every measurement. The biggest growth spurt for the plants under the green cellophane was from day seven to day nine. By day 13‚ the plants under the purple and red cellophane started to grow at similar rates as compared with those under the green cellophane. By day 32‚ the plants underneath the green

Light is everywhere in our world. We need it to see: it carries information from the world to our eyes and brains. Seeing colors and shapes is second nature to us‚ yet light is a perplexing phenomenon when we study it more closely. Here are some things to think about: Our brains and eyes act together to make extraordinary things happen in perception. Movies are sequences of still pictures. Magazine pictures are arrays of dots. Light acts like particles—little light bullets—that stream from the

WHAT IS PHOTOSYNTHESIS? 3 Every day the total amount of energy that is captured through photosynthesis all across our planet is equal to approximately 135 terawatts. Now to put this number into perspective the entire human race consumes approximately 15 terawatts of energy daily. This means that there is 9 times more energy being absorbed every day through photosynthesis‚ as there is energy being consumed by all of mankind (Bridges 2008). In order to fully understand photosynthesis

and I conducted an experiment about the photosynthetic rate of spinach discs. We were hypothesizing that if we place all 6 individual cups underneath a different color of light‚ the spinach discs that produce enough oxygen will have the highest amount rise‚ which will show us the optimal color of light for photosynthesis. These different colors of light included blue‚ red‚ green‚ fluorescent‚ regular light‚ and classroom light. The classroom light was our control cup during the lab. Before we conducted

Therefore‚ the aim of this study was to discovered the psychological effects of classroom colors upon children in kindergartens. The objectives for this research were firstly‚ to identify colors that can influence children behaviour. Secondly‚ to determine whether the colors scheme can effect the improvement of children development

Living things get energy to do things through photosynthesis‚ food molecule breakdown‚ build up‚ storage‚ and lastly cellular respiration. All of these ideas are the reason that myself and others have energy to do anything and everything. Photosynthesis is one way plants(plants are the main source of energy for all things)get energy to do things. The reactants of this are water‚ carbon dioxide‚ and although light energy is not a reactant‚ it is necessary once the energy from the seed is gone. Carbon

to them. In prokaryotes instead of chloroplast they use their own cell membranes to do the job. Wavelength also has a role in photosynthesis because they have just the right amount of energy to excite chlorophyll electrons boosting them to a higher energy level. When summing everything up the reactants are carbon dioxide‚ water‚ and the suns energy and the process is light dependent and the Calvin cycle. The products include oxygen and glucose. Pigments serve as photosynthetic organisms that capture

Light reveals a world of colors by painting everything it touches. Our plain and soulless furniture gains meaning. Our brown bookshelf‚ gray study table‚ green mug carpets‚ rugs‚ curtains the yellow wheat fields in the harvest picture‚ the blue china vase‚ our favorite brown sweater the striking green of a tree surrounded by concrete buildings‚ the blue sky‚ and the carousel of life that becomes worth living by being embellished with colors. Let’s travel through the wonderful world of colors.
