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, students carry out an investigation to determine the penetrating power of alpha, beta and gamma radiation. Required: Radioactive sources (AP8796) and Radiation Monitor (TC1618). 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™: Nuclear Radiation and Shielding
Concepts: Alpha/beta/gamma radiation, ionizing radiation, penetrating power, shielding
Outcomes: Different types of nuclear radiation require different types of shielding. When ionizing radiation strikes an atom, it transfers enough energy to the atom to strip it of an electron and create an ion. With each “strike,” the ionizing radiation loses energy. All forms of nuclear radiation have similar energies. The “speed” of the radiation, therefore, depends on its relative mass. The amount of “shielding” required to absorb nuclear radiation is proportional to the penetrating power. The ability of a material to absorb nuclear radiation depends on the density and the thickness of the material. The more electrons and nuclei there are in the path of the incoming radiation, the more effective the material will be in “stopping” the radiation. Alpha radiation has very low penetrating power and gamma has the highest. Alpha radiation is stopped by paper, beta by aluminum, and lead absorbs some gamma but not all of it. As the distance from the detector doubles, the radiation intensity decreases by a factor of four. The thicker the shielding material, the less radiation that penetrates.

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.
