In this laboratory activity, students were tasked with determining the heat of combustion for each of three common sugar substitutes: saccharin, aspartame, and sucralose. The heats of combustion were determined via three different methods: bomb calorimetry, heats of formation derived from semiempirical calculations, and tabulated average bond…

Starting the school year in an introductory high school chemistry class can be a challenge. The topic and approach is new to the students; many of the early chapters in the texts can be a bit tedious; and for many students the activities are uninspiring. My goal in the first few weeks of school is to hook the students on chemistry by getting them…

General chemistry students are asked to assume the identity of an element and to write their own story. In the spirit of pedagogical approaches such as writing-to-learn and writing across the curriculum, this assignment has several objectives, most significantly to connect students to the discipline of chemistry in a robust way. Facilitating this…

We present a writing task designed to increase students' awareness of chemistry-specific writing practices. This easy-to-use-and-grade task requires students to evaluate 10 short passages, a table, and a figure, representative of excerpts from Introduction, Experimental, Results, and Discussion sections of a journal article. Most of the items…

Scientific literacy is an important fundamental skill for scientists. In order for students to improve their writing they require constant feedback throughout the process. They also need to learn the value of the peer review process by experience. Although they may require submission of a rough draft, typical upper-division writing assignments…
