Theoretical Background The liquids commonly found around the house such as acetone‚ vinegar‚ hydrogen peroxide‚ and oil was tested to identify the physical and chemical properties of these liquids. Acetone usually used as nail polish remover dissolves plastic. Vinegar used in cooking and as a condiment begins to fizz when mixed with baking soda. Hydrogen

These alternative cleaners include food products such as vinegar or baking soda. Townsend‚ J (2007) mentioned that vinegar has versatile properties which can remove stains from many types of fabric. Baking soda is a leavening agent‚ enabling it to remove stains too‚ as stated by Lansky‚ V (2005). Lemon juice is natural and it contains citrus juice which not only removes stains‚ but

Methods/Materials I did three experiments. I mixed lemon juice and baking soda‚ammonia and vinegar‚ and finally‚ hydrochloric acid and sodium hydroxide. I did each experiment when the acid was 0‚ 20‚ 40‚ 60‚ and 80;all in degrees Celsius. Therefore‚ I could compare the exothermic reaction with the endothermic reaction at each temperature. For the Lemon Juice + Baking Soda experiment‚ I had a different set-up. On a beaker‚ which had baking soda in it‚ I put a stopper. The stopper had two holes that

Music‚ Math‚ and Science! by Mary Cozac Children learn concepts and develop through hands-on experiences. They learn to observe‚ question and be curious about their inside and outside environment. When children are encouraged to experiment and discover new things they acquire new concepts and new ideas which they transfer to other areas of development. Planned activities that explore music‚ math‚ and science can teach children many concepts and

make it burst into flames with 2‚085 degrees Fahrenheit lava dripping down; we are making “lava” come out made with soap‚ baking soda‚ vinegar‚ and a little food color to make the “lava” look pleasant. We have many questions about this project. I don’t want to spoil it to you right now though. We have three questions we are interested in. Our questions are: Does vinegar temperature affect how fast the volcano erupts? Which ingredient makes the liquid inside
