Conservation of Energy
Students analyze systems to demonstrate that energy is conserved, transforming between kinetic and potential forms without loss.
Key Questions
- Analyze how energy transforms between kinetic and potential forms in a pendulum.
- Justify the statement that energy cannot be created or destroyed.
- Predict the final speed of an object given its initial potential energy.

About This Topic
The study of Push and Pull Factors of Migration helps students understand the complex reasons why over 280 million people live outside their country of birth. By distinguishing between 'push' factors (like war or famine) and 'pull' factors (like job opportunities or religious freedom), students develop a nuanced view of human movement. This topic also introduces the critical distinction between voluntary migrants and refugees, a distinction that is central to modern global politics.
In a 7th grade context, this unit connects human geography to historical patterns of migration in the United States. It encourages students to look at the 'brain drain' and the cultural enrichment that follows migration. Students grasp this concept faster through structured discussion and peer explanation as they weigh the difficult choices families must make when deciding to move.
Active Learning Ideas
Role Play: The Migration Decision
Assign students family profiles with specific challenges (e.g., a drought-stricken farm, a job offer in a distant city). Students must discuss as a 'family' whether the pull factors of a new location outweigh the push factors of their home.
Gallery Walk: Stories of Migration
Display short narratives or primary source excerpts from various historical and modern migrants. Students move through the 'gallery' to identify and categorize the specific push and pull factors mentioned in each story.
Think-Pair-Share: The Impact of 'Brain Drain'
Students reflect on what happens to a town if all its doctors and teachers move away. They share their thoughts with a partner and then brainstorm ways a country might 'pull' its citizens back home.
Watch Out for These Misconceptions
Common MisconceptionAll migrants move because they want to.
What to Teach Instead
Many people are forced to move due to conflict or disaster. Using 'Role Play' helps students empathize with the lack of choice faced by refugees compared to voluntary migrants.
Common MisconceptionMigration only benefits the destination country.
What to Teach Instead
Migration often results in 'remittances' (money sent back home) and cultural exchange that benefits both sides. Peer discussion about local immigrant businesses can help illustrate these mutual benefits.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.

Introduction to Energy Forms
Students differentiate between various forms of energy (mechanical, thermal, chemical, electrical, light, sound) through examples and demonstrations.
3 methodologies
Kinetic Energy: Motion and Mass
Students investigate the factors affecting kinetic energy, specifically mass and speed, through hands-on experiments and data analysis.
3 methodologies
Potential Energy: Stored Energy
Students explore different types of potential energy (gravitational, elastic, chemical) and how they are stored and released.
3 methodologies
Thermal Energy and Temperature
Students differentiate between thermal energy and temperature, exploring how molecular motion relates to heat.
