Reviewer Comments:

In this lab activity, students will test a variety of foods for the presence of starch, sugar, and protein. For the experienced educator, this is a straightforward lab that can be immediately useful in the classroom. However, for a teacher new to the subject, it would be beneficial to have some sort of suggested timeline, explicit directions and objectives, and an expected answer key for this activity. For all levels of educators, this activity can be used immediately in the classroom with easily obtained materials, although the resource itself would be enhanced by the inclusion of some sort of data analysis or student assessment. This activity could also easily be modified for use with younger students.
