ReflectionI enjoyed researching this because it reminded me of being a child and watching storms from my bedroom window. I loved learning about weather in school, and I realized why while researching- it’s exciting! There’s all kinds of wild things that can happen in a storm. Lightning is very impressive, especially to a kid.I’ve used PowerPoint in the past, but this is my first time with the new program. I enjoyed exploring it and I found it’s even easier to use and to make things look professional. The interface is much better organized, too.APA citation was hard for me because this is my first time using it- in the past, I’ve only used MLA. I like that it still includes the web url address, unlike MLA; it makes it easier to find the source again. Back to Contents
