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 mass percent of bicarbonate in solid mixtures of metal bicarbonate and metal carbonate via thermal decomposition of the solid samples. They determine the Atom Economy of the reactions involved, and based on these values, they decide and explain which bicarbonate would be the greener choice as a food additive that generates carbon dioxide gas when exposed to heat. 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™: Green Chemistry Analysis of a Reaction
Concepts: Green chemistry, stoichiometry, percent composition, decomposition reaction
Outcomes: Students working with metal bicarbonate/metal carbonate mixtures will determine a mass percent of potassium bicarbonate of 60–70 percent in the KHCO3/K2CO3 sample and a mass percent of sodium bicarbonate of 40–50 percent in the NaHCO3/Na2CO3 sample. If students were given pure KHCO3 or NaHCO3 samples, the mass percent of bicarbonate should be closer to 100 percent in the respective sample. Upon calculating the Atom Economy (AE) for KHCO3 and NaHCO3 thermal decomposition reactions, they will determine that KHCO3 has a higher AE than NaHCO3. Hence, they may conclude that using KHCO3 is a greener choice.

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.
