In this 8-session course, students learn how to use a powerful 3D chemistry modeling software called ChemDoodle3D! ChemDoodle3D is used by science professionals to create high-quality molecular models and graphics for research papers. In this software program, students will have access to unlimited atoms and a molecule library to build complex molecular structures. No more running out of atoms parts when building molecule models! Learners will also be able to save and output their 3D molecule graphics as printable pages. The course starts off gradually to help learners acclimate to the software program, and then proceeds to explore complex molecules including proteins, carbohydrates, RNA and DNA. 

This course complements and moves beyond the Hands-on Molecule Building courses that we offer, since the software has more built-in resources and advanced features.

Please Note: Students will use the ChemDoodle3D software during this course, which can be downloaded and used for $18/month during the duration of the course (2 months, total cost $36). The software program can be downloaded for either Mac or Windows/PC computers. There is also a free 14-day trial available. Please see purchase info in the Supply List section for more details. 

This course has a Flexible Age Range. If a learner under the age of 10 has previously taken our Hands-on Molecule Building courses, and feels comfortable using a computer independently, then they may take this course.
