"If _____[I do this] _____, then _____[this]_____ will happen." Sound familiar? It should. This formulaic approach to making a statement about what you "think" will happen is the basis of most science fair projects and much scientific exploration. Following the scientific method, we come up with a question that we want to answer, we do some initial research, and then before we set out to answer the question by performing an experiment and observing what happens, we first clearly identify… Read more

Have you ever made ice cream? It can be a lot of fun, and you end up with a tasty frozen treat! There is actually a lot of interesting chemistry that goes on behind making ice cream. For example, think about how you start out with refrigerated (or room-temperature) ingredients and then need to cool them down to turn them turn into ice cream. How do the ingredients change during this process? How important do you think it is that they are cooled to a certain temperature? In this science… Read more
