• Asynchronous
• Laboratories
• University Partners
• Industry Partners

21
Vision Plans

• -- Students will have access
• to on-line labs with a
• variety of experimental systems
• in chemical and
• mechanical engineering

22
Vision Plans

• -- Students will be able
• to easily design and conduct experiments
• from home, dorm, computer lab or office
• -- Students will be able to compare
• local lab experimental results
• with on-line lab results

23
Vision Plans

• -- Faculty will have materials
• to implement remote laboratory
• experiments in their own institutions
• -- Faculty will have
• more diverse laboratory offerings
• -- Faculty will be able to easily use
• on-line labs in classroom demonstrations
