The topic of my STEM fair project is cookie taste and appearance. “ How does cream butter‚ melted butter‚ margarine‚ and shortening affect the taste and appearance of chocolate chip cookies”. The purpose of this experiment is to see which type of butter substance is best for bakers to use to make the best chocolate chip cookie. The information from this project will help people who love to bake‚ to find the best way to make cookies that their eaters will enjoy the most. All bakers around the

change‚ means there is no net loss or gain of water. Introduction This study shares the results of an effort to understand diffusion and osmosis in general. It focused more into osmosis in plants cell‚ and how to indirectly measure osmolarity in potato tuber tissue. Osmosis is the diffusion specifically of water across a membrane. Diffusion occurs when certain substance‚ such as an ion‚ is more concentrated on one side of membrane. If the membrane allows this ion through‚ the ions will move from

variables are the potato and onions. The dependent variable is the variable whose value is measured to determine the extent of the effect of another variable to it‚ as in an experiment. In osmosis lab‚ the dependent variable is the length of the potato. The controlled variables are the amount of water‚ amount of salt‚ and the size of the potato. If the potato is placed in a higher salt concentration‚ then the potato will decrease its size. We started the lab by cutting the potato core length (44

If the pH level of the solution is more basic‚ then the potato membrane will weigh less due to osmosis. Our null hypothesis was: If the pH level of a solution is either acidic or basic‚ then it will have no effect on the weight. The independent variable was the different solutions of different pH values. The dependent variable was the weight of the potato‚ which was measured in grams. The baseline of this experiment is the weight of the potato when in the milk solution because milk has a neutral pH

If I was meant to be controlled‚ I would have come with a remote. My life- i’m in control‚ or am I‚ I think that I am in control. Good morning gentlemen I am going to be telling you why I am in control of my life and that I can make my own decisions on things. My three main points are: 1 I choose to do hard challenges and chores because I benefit from it‚ 2 when do I become almost fully independent on my decision making‚ and 3 the people that influence my decisions and help me choose what decisions

Potato Catalysis Lab Pre-Lab Assignment Background Information: An enzyme is catalytic protein. It is the most important type of molecule found in living cells. Cells would not be able to function without enzymes. Enzymes speed up or slow down chemical reactions of the cells. It is usually easy to identify the names of enzymes because they end in -ase. The enzyme that acts upon the substrate hydrogen peroxide is usually called catalase. This enzyme is found in both plants and animals

Aim To observe and measure the effect of osmosis on the mass of potato using a starch solution. Introduction In order to measure the effect of osmosis‚ eighteen pieces of potato were cut and placed in six groups‚ each group of three pieces cut to weigh as close as possible to one another. For each potato group‚ a test tube was half filled with a starch solution varying in concentration from 0% (water) to 1%. Hypothesis Through osmosis

For this initial discussion I would like to contrast controlled laboratory experiments and naturalistic observations research methods. In controlled laboratory experiments‚ the researchers conduct their studies in a controlled setting. Conversely‚ studies involving naturalistic observation‚ examine participants in their natural environment. Below I present a contrast of the most essential features of each of these methods of research. Controlled laboratory experiments: • Objective: Seek to compare
