The Cabbage Indicator Experiment My hypothesis for this experiment is if I put an acid or a base in to a neutral then it will change colors. My hypothesis was correct in assuming that it would change colors with different substances or mixtures. If I put an acid or a base in to a neutral then it will change colors. The red cabbage indicator did change colors. Greens for bases and reds and pinks for acids. An alternative hypothesis for this could be “If the red cabbage indicator is purple then adding

The Rocky Shore Experiment Research Question: How does type of substrate affect the variation of species and vegetation as you move away from the seashore at a Rocky Shore? Hypothesis: As we get further away from the seashore‚ there would be a decrease in the number of species and vegetation found. Also‚ the type of substrate will have a major affect on the biodiversity. Background Information: A rocky shore is an intertidal area of seacoasts where solid rock predominates. Rocky shores are

Abstract: This experiment was completed with the intention of testing if two specific plants were allelopathic. Allelopathicity is defined as “They are allelon which means "of each other"‚ and pathos which means "to suffer". Allelopathy refers to the chemical inhibition of one species by another. The "inhibitory" chemical is released into the environment where it affects the development and growth of neighboring plants.” (Ref 1) Introduction: Have you ever wondered why certain plants do

molecules present. This will therefore make the experiment unfair‚ because the more pigment molecules present the more pigment molecules that can move out of the cell. Therefore the beetroot used should be freshly cut. pH The pH is also an important factor‚ as pH can have an effect on the weak interactions and bonds that bound the membrane together. To keep the pH constant it is important to make sure that the same surrounding are used for the experiment. Surface area. The surface area of the beta

Title Experiment with a spiral spring (Oscillation) Objective 1. To show how the time of vertical oscillation depends on the load 2. To determine the spring constant 3. To determine the effective mass of the spring Introduction In this experiment‚ it is to show how the time of vertical oscillation depends on the load‚ to determine the spring constant and to determine the effective mass of the spring. An ideal spring is remarkable in the sense that

what type of guard would you have become? How sure are you? If I were a guard I am sure that I would have been as nice as possible to the inmates. I would have done this so that I would have garnered their respect in order to avoid any conflict. 3. What prevented "good guards" from objecting or countermanding the orders from tough or bad guards? I feel that not wanting to feel alienated or be blamed for creating a sense of derision between the “bad guards” was what kept the good guards from objecting

damage to 14 % of its forest trees. In this experiment‚ I will find out what consequences acid rain has on the germination and subsequent growth of cress seedlings. I will use cress seedlings‚ which germinate quickly and can grow a few centimetres in a matter of days and sodium metabisulphite‚ which reacts slowly with water to produce sulphur dioxide gas. The seedlings will have to be in an enclosed system so the sulphur dioxide does not escape. The experiment is a simulation trying to model a powerstation

Cartesian Diver is named after the French scientist Rene Descartes. This experiment is supposed to show buoyancy‚ density and different forms of matter at work‚ when demonstrated. To create the Cartesian Diver‚ you’ll simply need: • A empty plastic bottle • A plastic eye dropper • Water 1. Fill the bottle with water‚ but be cautious of spills. 2. Very carefully‚ drop the dropper inside the bottle. Then‚ seal the cap on very tightly. 3. Squeeze the bottle‚ but not too tightly. Notice how the dropper
