What Amount of Water Grows the Plant the Longest? Daniel Rivera Alfonso Pineda Mrs. Fraijo AP Biology 10 June 2012 Abstract: In this experiment‚ 8 plants will be tested. Each except one plant (which will be the control group) will receive a certain amount of water starting at 0 teaspoons of water. Each plant will receive 1 more teaspoon than the previous cup‚ so it would be increasing. For example‚ cup 4 will have 4 teaspoons of water and cup 3 would have 3. The data recorded will be

purpose of this experiment was to discover if using sugar and tonic water with water would increase the growth rate of barley. In this experiment‚ we changed two variables‚ the independent variables sugar and tonic water. We added one tablespoon of each substance to four ounces of water which will be used to nourish the plant. We tested these experimental controls to determine if any of the substances would help accelerate the growth of the barley. If the sugar water or tonic water mixture successfully

In the beginning salt water and regular water got along. They all lived in the same ocean and each droplet would live in harmony. They shared the undersea environment with all the fish and sea plants. Some plants and animals needed salt water more than fresh water and some needed fresh water more than salt water. This is where the problem all started. The fresh water began to become jealous because the salt water was mocking the fresh water about them being the best type of water. It started out

The effect of salt concentration on grass growth Abstract Our aim was to test the effect of different salinities on the growth of plants which what we did was measured different amounts of salt dissolved into 2 litres of water‚ watered the plant once with the salt water then for 9 days with pure ware. I found with my investigation that the less the salt‚ the more the growth of the plant. My aim was achieved by measuring the 5 fastest geminating (out of 20) and to measure the differences in growth

Citric acid reacts rapidly with iron‚ but is not itself the rusting of iron. The water in the lemon juice helps iron rust‚ but in the presence of air. The same happens when you open bottle of Coca-Cola‚ including citric acid‚ phosphoric acid‚ carbonic acid and other things in the fall for the taste. Citric acid has an advantage over some other acids‚ because it is less corrosive‚ not as dangerous to the environment‚ while remaining efficient‚ cheap (but not as cheap as the old battery acid).

Water Rockets Abstract Water rockets have been a source of entertainment and education for many years. They are usually made with an empty 2-litre PET bottle by adding water and pressurizing it with air for launching. Water rockets are used to help students understand the principle of aeronautics. Aim The aim was to design and perform an experiment to determine the volume of water to use in order to obtain maximum height for the bottle rocket. Introduction Bottle rockets are often used in

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

There are fresh water fish in the fish hobbyist community known as algae eaters. I have narrowed my research to two algae eaters‚ the Chinese algae eater and the Plecotomus Fish from South America. The algae eater Fish needs to be affordable‚ an addition to my Fish tank‚ and Get along with all six Angelfish. Live in water temperatures of 78-82 degrees Fahrenheit‚ and not make a mess in the tank or destroy the vegetation already living in the aquarium. I have set up a point by point arrangement to

sauce for five minutes. Now it is time to add spices and salt. This will flavor the sauce and make it taste good. Then cook the sauce for another minute. Then you can add the water and bring it to a boil. After the water boils‚ you need to burn down the fire so that the chicken and sauce can simmer. Let it simmer for 20 to 30 minutes. Then it is time to add two cups of rice. Let the rice and sauce simmer. Cook this until all the water is absorbed by the rice. This will take about 15 minutes
