the most bubbles? If baking powder‚ baking soda‚ and salt are added to different test tubes of sugar water‚ then baking soda will have the most effect on the rate of fermentation (create the most bubbles). This hypothesis is rejected. Based off of data‚ the hypothesis was rejected. The ingredient that produced the most bubbles was baking powder. In the experiment finishing at 20 min.‚ the control had 2.5 cm of bubbles produced‚ the salt produced 1.5 cm of bubbles‚ the baking soda produced 1.5 cm of

see how the pill bug reacted with certain man made substances and two substances that they would find in their everyday habitat. We tested ketchup‚ orange juice‚ sand‚ baking soda‚ flour and water. The pill bugs did not like the ketchup and orange juice I believe because of the strong acidic smell and it didn’t like the baking soda because of the texture. The pill bugs didn’t have a problem with the water and sand because those two are found in the everyday life. The data that we found did not

The system in part 1 was to “pour the vinegar into the beaker that contains the baking soda”. The system in part 2 was to pour the vinegar in the plastic zip lock bag that contains the baking soda and then lock up the bag. The difference between the two is that in part 1 the experiment is out in the open‚ while the experiment for part 2 is enclosed in the plastic bag. 4. How can this

Kendall ABSTRACT The purpose of this research was to study the science of mummification by mummifying a Hungarian sausage using baking soda. The researchers tried to mummify three Hungarian sausages in baking soda over a period of more or less than ten days. On the first day‚ the researchers placed a Hungarian sausage in an air-tight container of baking soda and put it in a drawer for more or less than a week after measuring its length‚ circumference‚ and weight. After that a week‚ the researchers

substance #2 was baking soda. The evidence I found most persuasive was that substance 2 (baking soda) was found in the banquet hall owner’s house and all over the counter. Because the baking soda was spilled all over the counter and was also found in the banquet hall owner’s home‚ it proves that the hall owner was responsible for this crime. We would not have been able to make an educated deduction without performing the two tests. We would have needed to know what substance was baking soda by seeing how

Bibliography ……………………… pg. 15 Background Info When the two substances (vinegar and baking soda) mix‚ the vinegar‚ an acid‚ is creating a chemical reaction with the baking soda‚ a base. When the two substances form‚ it creates carbonic acid. When the two substances become a carbonic acid‚ it is unstable and decomposes to create carbon dioxide and water. The carbon dioxide is less
