The nine lessons contained in the Materials Science Classroom Kit, plus an additional six lessons are available to download for free if a lab is already equipped with the necessary components and supplies to perform the demonstrations. Three of those lessons require liquid nitrogen for those teachers who are able to obtain their own liquid nitrogen.
All of the free downloadable lessons we offer comply with the Next Generation Science Standards (NGSS), which are K-12 science content standards. Standards set the expectations for what students should know and be able to do. The NGSS were developed by states to improve science education for all students. A high-quality science education means that students will develop an in-depth understanding of content and develop key skills—communication, collaboration, inquiry, problem solving, and flexibility—that will serve them throughout their educational and professional lives.
