T he University of Colorado's spring semester kicks off Monday and students will have until Jan. 23 to make last-minute additions to schedules.

Students can add classes without an instructor's signature for the first 10 days of classes.

Whether they're looking to pick up extra credit hours, replace a dropped course or just want to try something different, these five courses can help fill the void.

Multimedia Sound

This collaboration between the English and ATLAS departments offers students an in-depth look at the nature of sound and how to use -- both from analog and digital perspectives.

Professor Ed Rivers said students are given the freedom to explore sound as it relates to their personal interest and hobbies. Student projects will utilize various mediums as sound effects, music and multimedia podcasts, he said.

Nutrition for Health and Performance

This Residential Academic Program creates a "live and learn" experience for students living in Sewall, Baker and Libby halls.

Instructor Donna Louie said the class covers nutrition basics, weight management, standards and guidelines, sports recommendations, agricultural practices and food policy issues.

The course includes field trips to local grocers to examine processed foods and to talk about labels, which Louie said is an integral part of the course.

Doing Business in China

This new course offered through Study Abroad and the Leeds School of Business includes an introductory session and five classes throughout the spring semester -- with the bulk of the class taking place in China during Maymester.

Leeds professor Tracy Jennings will take the class to China for two weeks to study the culture and business practices of one of the world's most influential economies.

The three credit hour course will cost students more than a traditional course, due to travel expenses.

Green Technology

This Environmental Design course is open to students across the campus and will encourage students to think green, while exploring their creativity.

Professor Julee Herdt challenges students to create two design projects from recycled or waste materials.

Students will learn about profits as they attempt to sell their projects, with the proceeds benefiting a local charity.

In the past, students have sold lamps made from car motors and plane parts, earrings made from vinyl, and furniture made from wood scraps at local furniture stores and art galleries.

Values and the Power of the Consumer in Society

This new Continuing Education course is open to all non-business students and incorporates the values of the business school's Center for Education on Social Responsibility.

Instructor Scott Gwozdz will help students become responsible consumers by examining ethics surrounding consumerism through companies like Toms Shoes and Coca-Cola.

Guest speakers will elaborate on the marketing and branding strategies behind company ethics and will also look at how social media plays a role.
