360Science™: Energy Densities of Organic Fuels
Concepts: Chemical reactions, combustion reactions, energy transfer in chemical reactions, law of conservation of mass
Outcomes: Students should come to understand that different fuel sources have different chemical compositions and therefore different chemical structures. When a fuel burns, the bonds that hold its constituent atoms together break on the reactant side of a chemical equation and then reform on the product side of a chemical equation. This process results in the release or absorption of energy. We can calculate the amount of energy associated with a chemical reaction by indirectly monitoring its temperature (i.e.,the temperature of water the reaction is used to heat). Students should recognize that despite evidence to the contrary (e.g., the burning of charcoal or ethanol), mass is not destroyed in a chemical reaction, only transformed.

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.
HS-PS3-1. Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
