Spreadsheets put numbers into rows and columns, where those numbers can be placed into formulas and calculations, or sorted to improve understanding. The use of a spreadsheet can help to build understanding from data and other information, because it can be manipulated and charted. For students working with data about scientific phenomena, a spreadsheet can be a way to quickly make and test hypotheses about relationships. For example, using a spreadsheet that contains data about the length of gestation, life span, and average number of offspring for various animals can help students explore concepts about how those elements may be related. Students can also use spreadsheets to easily perform complex calculations, which removes computation errors as a factor leading to misunderstanding. Spreadsheet software can accept data from a variety of sources, including survey exports, complex data sets, and even geo-tagged elements. As spreadsheets continue to become more powerful, it will be important that students understand the relationship between data and display, so that they can be informed consumers of information.
Presentation software places text, audio, and visual elements into a slideshow format that can be displayed in a variety of formats for a variety of audiences. In our increasingly graphic-intensive world, students must understand the impact of visual presentations, not just be the passive recipients of them. Elements of design can be used to manipulate emotions; when students are aware of design elements, hopefully they will be less likely to make decisions solely on the visual. Like word processing and spreadsheets, many presentation tools are cloud-based and collaborative, allowing students to effectively work together in the development of presentations. Ideally, students use presentation software as a storyboarding tool, planning the text, audio, and visual elements that will best convey their message to their audience. In all content areas, including science, the standards ask students to make an argument based on evidence. Creating that argument in a presentation format and sharing it to an authentic audience gives students a real-world experience, imitating the presentations required by scientists around the world as they share their results with their colleagues and the public.

NIce summary of the advantages of using the three. As a science teacher, I especially like "In all content areas, including science, the standards ask students to make an argument based on evidence. Creating that argument in a presentation format and sharing it to an authentic audience gives students a real-world experience, imitating the presentations required by scientists around the world as they share their results with their colleagues and the public." Absolutely, agree!
