In this lab activity students performed an experiment with the use of distilled water and baking soda solutions as control. The experimental controls are accuracy indicators of laboratory results. Thus‚ controls are important in a lab because the observation results are dependent on the controls. The experimental results can be determined to be valid when it is compared with the control solution. The higher the similarity between the results and the control solution‚ the more accurate the investigation

Mixing Mixing of ingredients is a critical factor to the quality of the final product as any other step in the baking process. It can be done manually or with a mixer (Pellegrini‚ 2012). In mixing‚ air cells are formed that enables leavening. At the beginning of mixing‚ air cells are large but as mixing continues‚ these cells become divided into smaller ones as gluten and other proteins develop and stretch. This entails that the length of mixing is important in achieving a desirable texture for

to take a variety of solutions and test their pH. Due to materials available pH strips were the only testing tools available. A table is setup to compare the strip color to its pH level. Four known solutions including bleach‚ lemon juice‚ soda‚ and baking soda were used. There was also an unknown solution in which the pH level was used to determine which solution it was. The pH scale is 1-14‚ a pH of 7 is neutral‚ less than 7 is acidic‚ and greater than 7 is acidic. Materials: * pH strips

well. To remove each stains from the fabric I used baking soda‚ ketchup‚ Gatorade‚ lemon juice‚ detergent‚ and just water. The investigation I conducted was‚ “What household items can you use to remove a stain the best.” For my procedure‚ I cut out six pieces of a cotton tee-shirt and applied one tablespoon of a grape juice stain. One tablespoon of the grape juice stain was added to each piece of fabric. Next‚ I added one tablespoon of baking soda‚ ketchup‚ Gatorade‚ lemon juice‚ detergent‚ and just

The name of the alka seltzer project is named “The Dropouts.” The significance of that name is that the owners of the machine are very close to dropping out school themselves. Ultimately‚ the goal of the machine would be to pop a balloon and to blow out a candle. The goal would be achieved by using the potential energy in the balloon‚ popping it‚ and using the now present kinetic energy‚ which is the air‚ to blow out the flame of the candle. The final products would be a popped balloon and a blown

Baking soda can also cause issues with the rising in the dough. Make sure you store your baking soda properly. Store it in a dry and cool place. After I open mine‚ I pour it into a plastic bag and keep it in the cabinet with the rest of my baking ingredients. This ensures that the humidity in the air

Project Proposal Project Title: Manglue Significance of the Study Mango trees are one of the major sources of food in our country. Mangoes are very wide-spread in the Philippines. An adhesive‚ or glue‚ is a mixture in a liquid or semi-liquid state that adheres or bonds items together. Glue is very important‚ not only to students but also to other people. Glue is often used for projects‚ or generally in our daily lives. The purpose of “manglue” is to use extracts of mango as an alternative ingredient
