Students study a structure made from Lego blocks for several minutes. After this examination, during which no notes or drawings are made, they attempt to build the structure without looking at the original. During a second examination of the structure, students are allowed to write instructions in words for the building of the structure. After the instructions have been written, they are passed along to another student, who then attempts to recreate the structure using the instructions, without looking at the original. Comparison of the recreated structures to the original helps to illustrate some important concepts of laboratory report writing.

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students.
Occasionally, collections of JCE back issues become available for donation to individual teachers, schools, or libraries. JCE matches collections with interested recipients. Recipients pay shipping costs or pick up the collection.
