How does information get from one place to another so quickly? In the Get Critical! STEM Kit, students will conduct experiments with optical fibers to learn about reflection, refraction, critical angles, and diffraction. They even get a chance to send “text messages” between groups!
Big Concepts include: 1) reflection; 2) refraction; 3) density; 4) critical angles; 5) diffraction; and 6) wavelengths of light.
Scientific Inquiry Skills include: 1) measuring critical angles; 2) data collection and graphing; 3) use of spectroscope; and 4) use of science notebooks.

Borrowing Get Critical! STEM Kits
There is no charge to educators who wish to borrow any of our STEM kits. Educators who are located in the Northern Colorado area and can come to the CSU Fort Collins campus to pick up the kits should complete the Local Pick-Up Loan Application. All other educators in Colorado should complete the Delivery Loan Application Form and the NSEOC will ship the classroom set of kits to you free of charge. Return loan application forms to Courtney Butler via email (firstname.lastname@example.org) or fax (970-491-7716).
- Local Pick-Up Loan Application Form – for educators in the immediate area of Fort Collins (i.e.: Greeley, Loveland, Ault, Windsor, Johnstown, etc.)
- Delivery Loan Application Form – for educators in Colorado outside of the immediate Fort Collins area
- Educator Feedback Survey – must be completed after returning kits to the NSEOC and before another kit can be requested
