Today we worked on observations, by recording details of apples and then studying how a starch packing peanut dissolves in water. This led to our next discussion about scientific methods: asking questions, and coming up with testable ideas. What follows is a list of questions the students had about packing peanuts. With my help, they then decided on which questions were testable in our classroom (highlighted in green).
Of course, that we’re not going to test #1 is a major disappointment! Next day’s plan is for the students to split up and devise an experimental plan to test one question (per group). With these activities, we will go over experimental design and controls in an interesting and authentic way.
