Erosion and Deposition: Moving Earth Materials
Students investigate how water, ice, wind, and gravity transport weathered materials and deposit them in new locations.
Key Questions
- What role does vegetation play in preventing the loss of soil?
- How do human activities accelerate the natural process of erosion?
- Compare and contrast the erosional and depositional features created by glaciers and rivers.

About This Topic
Public Health & Innovation examines the unique health challenges faced by African nations and the creative ways they are using technology to solve them. Students explore the impact of diseases like Malaria and Ebola on economic growth, and how mobile phone technology has revolutionized healthcare delivery in rural areas through 'm-health' apps. The unit also covers the role of international aid and the importance of local leadership in health crises.
This topic is a vital study of how human ingenuity can overcome geographic and economic barriers. It aligns with standards regarding the impact of health on human development and the role of technology in improving quality of life. Students grasp this concept faster through structured discussion and peer explanation as they analyze real-world case studies of health innovation.
Active Learning Ideas
Inquiry Circle: The M-Health Challenge
Groups are given a specific health problem (e.g., tracking a disease outbreak or reminding patients to take medicine). They must 'design' a simple mobile app or SMS-based system to solve it in a rural area with no internet.
Gallery Walk: Innovations in Health
Display posters of various African-led health innovations (e.g., drone delivery of blood, low-cost water filters, or community health workers). Students rotate to identify how each innovation addresses a specific geographic barrier.
Think-Pair-Share: The Link Between Health and Wealth
Students discuss how a healthy population helps a country's economy (more workers, fewer hospital costs). They share with a partner why investing in health might be the best way to help a nation grow.
Watch Out for These Misconceptions
Common MisconceptionAfrican nations only rely on Western aid for health.
What to Teach Instead
Many of the most effective health solutions are developed and led by African scientists and community leaders. The 'Innovations in Health' gallery walk is essential for highlighting local agency and expertise.
Common MisconceptionDiseases in Africa don't affect the rest of the world.
What to Teach Instead
In a globalized world, health crises can spread quickly across borders. Peer discussion about the Ebola or COVID-19 pandemics helps students understand the importance of global health cooperation.

Planning templates for Science
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.
