I would use this video when exposing students to the contributions different scientists have made. Madam Curie and her husband worked together for years to discover the power of radium and polenium for healing disease.I utilize YOUTube, Discovery Ed., and EduSmart for videos. These enhance the chIildrens understanding because they are oriented for elementary students. I learned that you are permitted to make one copy of sources for each student. I know there are copyright laws that limit how you use materials correctly. I will be able to use Dropbox in my classroom to share lessons, power points, and videos with my students.
