CO.1. Physical Science

1.1. Energy comes in many forms such as light, heat, sound, magnetic, chemical, and electrical. Students can:

1.1.a. Identify and describe the variety of energy sources
1.1.b. Show that electricity in circuits requires a complete loop through which current can pass
1.1.c. Describe the energy transformation that takes place in electrical circuits where light, heat, sound, and magnetic effects are produced

CO.2. Life Science

2.1. All living things share similar characteristics, but they also have differences that can be described and classified. Students can:

2.1.a. Use evidence to develop a scientific explanation of what plants and animals need to survive

2.2. Comparing fossils to each other or to living organisms reveals features of prehistoric environments and provides information about organisms today. Students can:

2.2.a. Use evidence to develop a scientific explanation for:
2.2.a.1. What fossils tell us about a prehistoric environment
2.2.b. Analyze and interpret data to generate evidence about the prehistoric environment
2.2.c. Evaluate whether reasoning and conclusions about given fossils are supported by evidence

2.3. There is interaction and interdependence between and among living and nonliving components of ecosystems. Students can:

2.3.a. Use evidence to develop a scientific explanation on how organisms adapt to their habitat
2.3.b. Identify the components that make a habitat type unique
2.3.c. Compare and contrast different habitat types
2.3.d. Create and evaluate models of the flow of nonliving components or resources through an ecosystem
2.3.e. Make a plan to positively impact a local ecosystem

CO.3. Earth Systems Science

3.1. Earth is part of the solar system, which includes the Sun, Moon, and other bodies that orbit the Sun in predictable patterns that lead to observable paths of objects in the sky as seen from Earth. Students can:

3.1.a. Gather, analyze, and interpret data about components of the solar system
3.1.c. Gather, analyze, and interpret data about the Sunrise and Sunset, and Moon movements and phases
3.1.d. Develop a scientific explanation regarding relationships of the components of the solar system
