## Tools for the classroom

Transformation 2013 is proud to provide STEM educators a variety of tools to enhance and broaden experiences in science, technology, engineering and math. We also want to emphasize online resources that help both students and teachers in preparation, analysis, research and more. So you can order term papers online when you don't have time or don't know much about the topic.

Powered by National Instrument's LabVIEW and developed in conjunction with Transformation 2013, the Virtual Instruments (VIs) provide opportunites for rigorous math and science concepts to come alive. Educators, students, parents and community members are invited to download the VI to enhance the learning experience.

To utilize the VIs, version 8.5 or newer of LabVIEW or the LabVIEW Run Time Engine (RTE) must be installed on the computer. The LabVIEW RTE can be downloaded by choosing the appropriate operating system below. Once downloaded, the RTE must be installed on the computer where the VIs will be utilized.

Watch the VIs in action!
