In this guided inquiry lab, students use molecular model kits (not included) to create 3-D models that illustrate the ways carbon combines with other atoms to form more complex molecules. The lab guides students in creating 15 molecules using a variety of single, double and triple bonds. The models increase in difficulty from simple molecules to ions to carbon rings.
Students do the following for each molecule:
❶ Calculate the necessary number of bonds.
❷ Draw the Lewis dot structure.
❸ Build and then draw the molecular model using correct geometry.
This is a great way to challenge first year Chemistry students. By determining which modeling components they need and using those parts to solve for the final design, they learn how molecular structures work and gain the knowledge and confidence to solve more advanced problems.
Also included is a second student worksheet that has two customizable headers so that you can modify the lab to better fit your needs.
