360Science™: Titrations—The Study of Acid–Base Chemistry
Concepts: Molarity, acid–base titration, indicators
Outcomes: Titration is a very important technique in chemistry and is used more in the everyday world than students realize. This lab gives them a chance to learn and practice that technique. It also shows them that even when you prepare a solution, it can be important to verify its exact concentration. Sometimes even little discrepancies can make a difference in how an experiment is run and what conclusions are reached. But it also shows the limitations of certain techniques and what information can be learned with them. The titration technique is one of many essential tools for chemists and can help students appreciate the need for precision and the variety of data that can be obtained with it.
Associated Phenomena: How does acid rain impact the environment?
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.
