In this experiment we're going to find out the difference between baking powder and baking soda, two common ingredients in cakes, cookies, and other yummy foods. To figure it out, we're going to do something called an unknown test, which is used tell two substances or mixtures apart based on their chemical differences.
It works like this: say we accidentally mix up a bowl of salt and a bowl of sugar, two substances that look nearly identical. In the kitchen, we can easily tell the two apart. How? We just taste a tiny bit. In the lab, however, we never want to taste our materials unless we know it's completely safe (plus, they might taste bad!). Because we can't use sight or taste, we have to test the chemical properties of each substance to tell them apart.
Hmm... it seems nobody's added a conclusion for this experiment yet. You can suggest one here.
