Comments about Including the Science and Engineering Practice
The focus of this lesson is on the explanation of a phenomenon by having students respond with their observations. They are also instructed to measure the length of time the balloon sticks to the wall. To enhance this practice, it is suggested that instructions to make observations be explicit, and that students record their observational and measurement data in their science notebooks. For third graders, a data table template, or instruction on how to create a data table is recommended to aid them in the recording of data. It is important to note that the "Observations and Results" section of this resource refers to wool as a conductor which is inaccurate. This misinformation is not important to the overall investigation as students should be focused on explaining the cause-effect relationships between the materials and behaviors, and not the mechanisms of static electricity such as the passing of electrons.
