Science Curriculum: Middle School

Science Elementary Curriculum

In Montgomery County Public Schools, the goal of the science program is for all students to achieve full scientific literacy through Next Generation Science Standards aligned and phenomenon-based instruction that will prepare them for success in college and career. The MCPS science curriculum was developed as a coherent learning progression from kindergarten through grade 12 where all students experience a rigorous, interdisciplinary approach to science content, exploring science through hands-on explorations, productive discourse, and purposeful reading and writing. Students apply content knowledge through the scientific and engineering practices to solve real world problems and develop the tools that will make them successful lifelong learners.


Grade Course Information

Investigations in Earth Science Course Syllabus

Course Storyline:

Students in the Investigations in Earth Science course will develop understanding of 5 major concepts of Earth science that include the Earth’s surface systems, weather and climate, the Earth's Interior systems, the history of Earth, and natural resources and human impacts. While each of these concepts will be taught in isolated units, Investigations in Earth Science will also revisit related concepts throughout the school year to show the interconnected nature of all of the Earth Systems: the hydrosphere, geosphere, atmosphere, and biosphere. The theme of climate change, both natural and manmade, will also be woven throughout the units to develop student understanding of this important issue and to create a consistent year long storyline.


Teaching & Instruction:

The course is taught through hands-on explorations, productive discourse, and purposeful reading and writing. The curriculum is problem/project-based where students apply their understanding of science, technology, engineering, and mathematics (STEM) to propose solutions to real world phenomena/problems. Students are awarded 10 SSL hours at the completion of Grade 6 Science for their full participation in SSL activities related to their Outdoor Education experience.


Unit Descriptions:

Unit 1 - Our Watershed, Our World explains the environmental impacts that increasing populations have on the Earth and the techniques used to assess a community's effect on its local environment.

Unit 2 - Atmospheric Phenomenon demonstrates how changes in atmospheric variables such as density, unequal heating, air pressure, and moisture leads to the weather events that humans' experience daily. The unit also investigates the relationship between ocean currents, land masses, and other Earth features that affect global weather patterns and climate.

Unit 3 - Dynamic Earth explores the conditions within the Earth responsible for the geologic processes that shape the landscape around us and processes on the Earth's surface that alter that landscape over time.

Unit 4 - Earth's Geologic Past examines the 4.5 billion year history of the Earth, the major events that have occurred through time both geologically and biologically, and how scientists use relative and absolute aging techniques to organize these events into a Geologic Time Scale.

Unit 5 - Earth's Resources & Human Impacts identifies the impact the human population increases and per capita resource consumption has on the natural world and how usage of these resources carelessly is leading to the depletion of resources, climate change, pollution of our natural environment, and other major impacts felt worldwide.

Unit Anchoring Phenomena

Forces, motion, and interactions encompasses the mechanical branch of physics, studying the nature of forces and its impact on the motion of objects.  Students will learn that the motion of an object is determined by the sum of the forces acting on it and that the greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion. Forces on an object can also change its shape or orientation.  Using these learned concepts, students will create a design for an advanced rocket capable of launching large payloads and crew to Earth’s orbit.
