We follow the Next Generation Science Standards (NGSS) for Middle School. Douglas County School District has divided up the standards so that students will have Physical, Earth, and Life Science concepts each year of middle school. (Grades 6-8). 

Physical Science
The fact that matter is composed of atoms and molecules can be used to explain the properties of substances, diversity of materials, states of matter and phases of changes. Some examples of activities may include the following or similar:

ACS Chemistry for Life: Changes of State

 PhET: Build A Molecule

 Science Scope: Oobleck Is it a solid or a liquid?

Reacting substances rearrange to form different molecules, but the number of atoms is conserved.  Some reactions release energy and others absorb energy. Some examples of activities may include the following or similar:
ACS Chemistry for Life: What is a Chemical Reaction ACS Chemistry for Life: Energy Changes in Chemical Reactions Science4Inquiry.com: Maintaining Mass

Earth Science
Water cycles among land, ocean, and atmosphere, and is propelled by sunlight and gravity.  Density variations of seawater drive interconnected ocean currents.  Water movement causes weathering and erosion, changing landscape features. Some examples of activities may include the following or similar:

NSTA Science and Children: Uncovering Representations of the Water Cycle - a formative assessment probe EarthLabs: Where’s the Water? National Weather Service: What-a-cycle UCAR Center for Science Education: The Water Cycle Office of Energy Efficiency and Renewable Energy: Energy of Moving Water Science Scope: Classroom-Scale Experiments with Application to the Global Water Cycle Science Scope: Supporting Student Understanding of Models by Using Multiple Models Science Scope: Teaching the water cycle USGS: Water Science School

Humans depend on Earth’s land, ocean, atmosphere, and biosphere for different resources, many of which are limited or not renewable.  Resources are distributed unevenly around the planet as a result of past geologic processes. Some examples of activities may include the following or similar:
Discovery Education: Patterns of Natural Resources


Life Science
Organisms and populations of organisms are dependent on their environmental interactions both with other living things and with nonliving. Some examples of activities may include the following or similar: Annenberg Learner: Interactive Labs Ecology Lab

Ecosystems are sustained by the continuous flow of energy, originating primarily from the sun, and the recycling of matter and nutrients within the system. Some examples of activities may include the following or similar:
Ambitious Science Teacher: Ecosystems and Southern Resident Orcas PBS Learning Media: Exploring the “Systems” in Ecosystem

Ecosystems are dynamic in nature; their characteristics can vary over time.  Disruptions to any physical or biological component of an ecosystem. Some examples of activities may include the following or similar:
PBS Learning Media: Florida’s Everglades: The River of Grass

Biodiversity is the wide range of existing life forms that have adapted to the variety of conditions on Earth, from terrestrial to marine ecosystems. Some examples of activities may include the following or similar:
TeachEngineering: Cleaning the Air
