This resource appears to be designed to build towards this science and engineering practice, though the resource developer has not explicitly stated so.
Comments about Including the Science and Engineering Practice
The website specifically lays out the difference between demonstrations/activities and what they call “a science fair project” (i.e. an investigation). Suggestions are given for how to turn the one into the other. Teachers could also encourage kids to go above and beyond the suggested investigations, using the website’s reminder to “change something, create a new test, and then compare results.”, and “only change one thing at a time. Observe what happens, document your results, and get ready to share your discoveries”. Although this language is vague, the underlying idea is sound, and does include sometimes-overlooked steps of comparing results and sharing discoveries. Students can also be encouraged to phrase their investigation topic in the form of a question, to strengthen the idea that scientific investigations use evidence to answer questions. The teacher can support this by having the students share their “answers” and discoveries in the form of teacher-provided questions, or a brief oral summary for the class, or a poster, lab report.
