Open vs. Closed Systems
Open vs. Closed Systems is a skill on Pengi from Lesson 1: Tracing Matter in Amplify Science (California) Grade 7.
Key Concepts
To verify that matter remains, scientists use closed systems where nothing can escape. If you burn steel wool inside a sealed jar, the total mass stays exactly the same.
This experiment provides proof that atoms are not lost; they are just transforming into products that might be difficult to capture in an open system .
