Activity/Assignment • Bubble Scenario Entry Task • Get checked off for your DNA and Proteins EOC Review Sheet

Studying Ecosystems

• Why are scientists interested in ecosystems? We want to know: • What defines our environment • What makes a healthy environment • How can humans sustain a healthy environment for the future Many ecosystem studies are looking at how matter and/or energy move from one place to another

Open vs Closed Systems

Open System • Allows energy to go in and out • Allows mass to go in and out • Examples: • Fish tank • Classroom Closed System • Allows energy to go in and out • Does not allow mass to go in and out • Examples: • Mealworm Biochamber
