360Science™ blends the best of student-engaging digital content with easily adaptable hands-on labs to offer your students a uniquely comprehensive learning experience.
In this lab experience, six groups of students use a separation technique known as gel electrophoresis to separate segments of deoxyribonucleic acid (DNA) or proteins according to the size of the segment and the relative electric charge of that segment. Students measure each of four DNA fragment bands from a simulated crime scene sample and from three “suspects.” The students use the “police report” and the results from the electrophoresis to formulate an explanation of which suspect they believe is the criminal. Editable, differentiated instructions range from a time-sensitive prescriptive lab to full open inquiry, and robust online videos and content—including a virtual reality (VR) simulation—help students prepare for and better understand the labs they’re conducting.

360Science™: DNA Forensics
Concepts: Gel electrophoresis, DNA, Restriction Fragment Length Polymorphism (RFLP), Variable Number of Tandem Repeats (VNTR)
Outcomes: Students have the opportunity to work with the gel electrophoresis and discover the importance of such techniques to solve a variety of real-world mysteries—from medical to criminal! Each lane (the three suspects and the crime scene) will produce four different, visible fragment bars.
Associated Phenomena: Genetic Mysteries
Our 1-year option provides access to all digital content for one year plus lab supplies for a single class of 30 students. Our 3-year option extends access to digital content to three years, with a 30% discount on refill supply kits years 2 and 3.
What is Flinn 360Science™?
We’re introducing a whole new way to teach experiential science! We’ve taken a hard look at science study from all perspectives and, thanks to the feedback of thousands of teachers nationwide, we’ve created a way to make it easier to provide personalized instruction while delivering the kind of lab experiences your students truly need.
Our new and comprehensive learning solutions are designed to bring science to life by giving you all the tools you need to incorporate more (and effective) hands-on learning in your classroom or lab. 360Science allows you to provide your students with the support they need to make real-world connections to key scientific principles and help make those abstract concepts concrete.
Every 360Science lab solves the most common challenges educators face in bringing more hands-on science to their students—from not having enough time to matching the right level of challenge for students’ abilities to providing appropriate background content, safety techniques, assessments and more.
Enable student-driven, blended learning through a unique combination of leveled lab instructions supporting prescriptive, guided- and open-inquiry lab exercises (see PDF resource for specific details) with robust digital content, such as videos and carefully curated Open Educational Resources (OER)—along with virtual reality and simulation exercises. From editable, digital instructions to assessments and alignment with Next Generation Science Standards (NGSS), we have everything you need to improve mastery, remove the intimidation factor and foster your students’ natural curiosity.
