Safe-D researchers at TTI are now offering an at-home lesson for students grade 4 to 6 on the science behind reflective road signs, a property called retroreflectivity.
TTI’s unique educational program on Retroreflectivity is now online for parents and their students to learn about how roadway objects such as street signs can be seen at night. This at-home lesson is designed to spark curiosity in students in grades 4 through 6 by teaching them about science and engineering through an interactive hands-on experience. The materials for this project can already be found in most homes. More information with a link to the instructions and videos for how to conduct the lesson can be found below:
