360Science™: The pH of Seawater
Concepts: Ocean water pH, carbon dioxide uptake, seawater chemistry
Outcomes: Students will observe that the dissolution of carbon dioxide gas into a saline solution that resembles seawater causes a decrease in the pH of the solution. This change in pH will be measured directly with a pH meter. Also, the change in pH will cause the change in color of the solution due to the presence of an acid–base indicator.
Associated Phenomena: How does ocean acidification affect coral reef?
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-PS1-5. Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
HS-PS1-6. Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.
HS-ESS2-2. Analyze geoscience data to make the claim that one change to Earth’s surface can create feedbacks that cause changes to other Earth systems.
