SCIENCE HOW DOES COLOUR AFFECT PLANT GROWTH? AIM To find out if colour affects plant growth‚ and if plants are adaptable to the colour of light‚ and how much light it gets. INTRODUCTION For this Science assignment‚ I chose to find out if the colour and amount of light a plant receives‚ affects plant growth. Light is electromagnetic radiation that comes in waves‚ the basic units of which are called photons. Plants use light to turn carbon dioxide into sugars necessary for growth‚ a process called

How is saltwater affecting our drinking water? Saltwater is becoming a problem to our drinking water because it is getting into the rivers that we get our drinking water from and it and the saltwater it is also intruding aquifers. The place where you can see the most change is in Florida because of the climate change. Because whenever it floods in Florida the seawater gets into the rivers and also seeps into the grounds. When it seeps into the ground it gets into the aquifers and that’s how Florida

mean root growth was for water treated B.pumilus and the lowest mean root growth was the salt water treated control. Water treated V.paradoxus has a higher mean root growth compared with salt water‚ with a high margin of error. B.pumilus has the largest difference between root growth between water treated and salt water treated. (Table 1) Table 1: Individual results of Brassica mean root growth (mm). These were treated with Bacillus pumilus and Variovorax paradoxus under water and salt water (100mM

put in salt water? Purpose: I want to know why the egg floats in fresh water and not salt water. I want to know if the egg will float in salt water‚ Also this shows why materials float easier in saltwater and sink in freshwater. Research: Since the egg’s density is higher than the density of freshwater the egg will sink. Density is mass per unit volume‚ which means a measure of how much mater is in a certain volume. If you add enough salt the egg will float again. The salt makes the water denser

Part A: Title: Diffusion Diffusion is the spontaneous movement of particles from where they are more concentrated to where they are less concentrated. For this experiment‚ a 14 cm glass was filled with cold tap water. A drop of red food coloring was dropped in the cup. A stopwatch was used to measure the time it took for the food coloring to get to the bottom of the cup. The average diffusion rate was .78 cm a second. If a different color was used‚ I do not think it would have made a difference

The effect of salt concentrations on the mass of the pear cubes ‘Pyrus’ after being soaked in water Aim: The effect of salt concentrations on the mass of the pear ‘Pyrus’ pieces shaped as cubes of 1cm. Background: Osmosis is the net movement of water molecules through a semi-permeable membrane from an area of higher water potential to an area of lower water potential. Water makes up to 70-90% of living cells and cell membranes are partially permeable membranes. Dissolved substances attract

The relationship between democracy and economic growth has generated much controversy‚ research‚ and even bewilderment. If economic development is an expression of the level of development of societies‚ it will also be compatible with the level of democratic development. Democracy will become a catalyst and engine of economic and social development in society. To what extent does the economy affect the building of democracy? Is democracy a condition for economic development‚ or is economic development
