Maryland Standards

MD.2.0. Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
2.C.1. Plate Tectonics: Gather information and provide evidence about the physical environment, becoming familiar with the details of geological features, observing and mapping locations of hills, valleys, rivers, and canyons.
2.C.1.a. Identify and describe some natural features of continents: Mountains; Valleys; Rivers; Canyons.

MD.3.0. Life Science: The students will use scientific skills and processes to explain the dynamic nature of living things, their interactions, and the results from the interactions that occur over time.
3.E.1. Flow of Matter and Energy: Recognize that materials continue to exist even though they change from one form to another.
3.E.1.a. Identify and compile a list of materials that can be recycled.
3.E.1.b. Identify what happens to materials when they are recycled.
