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 perform two titrations with acids and bases of their choice to determine the unknown concentration of one acid and one base. They will further explore pH and titrations by graphing their data to create a titration curve. This allows them to see the different types of curves that result from different strengths of acids and bases being titrated. Students also observe how titration curves differ between mono and diprotic acids. 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™: Acid–Base Titrations
Concepts: Strong and weak acids/bases, equilibrium constant, titration, indicators, equivalence point
Outcomes: Titration is an invaluable technique in chemistry that students do not often appreciate. This lab has students refine their technique and take careful measurements to produce titration curves. Unlike other titration labs, here students are choosing unknowns to evaluate, which means they must also decide on an appropriate indicator. Titration curves can help students visualize how weak and strong solutions differ. If you are working with a true unknown, the shape of the curve and steepness of the transition can help identify whether the solution is strong or weak. This can always be expanded to polyprotic acids to show students how the curves change as a result of two protons being present.

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.
