Windbreak Designers: Preventing Land Changes

Grade 2Science3 days
In the Windbreak Designers project, second-grade students explore and test the effectiveness of windbreaks made from natural materials to prevent land changes and protect the environment. Through activities like live demonstrations of wind erosion and hands-on design challenges, students learn about the role of windbreaks and compare different designs to mitigate wind erosion effectively. The project also emphasizes collaboration, scientific inquiry, and understanding of Earth's landforms, aligning with Next Generation Science Standards to encourage evidence-based environmental problem-solving.

Essential Questions

Supporting questions that break down major concepts.
  • What is a windbreak and how does it help prevent changes to the land?
  • How can different designs of windbreaks protect the land from wind erosion?
  • What Earth events can change the shape of the land quickly, and which ones happen slowly?
  • How do shrubs, grass, and trees contribute to holding back the land?
  • What types of land and bodies of water exist in our study area?
  • Why is it important to design solutions to prevent land changes caused by wind or water?

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:
  • Understand the function and importance of windbreaks in preventing wind erosion and land changes.
  • Design and test multiple windbreaks using natural materials to assess their effectiveness against wind erosion.
  • Analyze and compare different windbreak designs to understand their impact on preventing environmental changes.
  • Develop models to represent land shapes and features, and understand their interaction with windbreaks.
  • Investigate various Earth events that cause land changes, differentiating between those that occur quickly and those that are slow.

2-ESS2-1
Primary
Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land.Reason: The project involves designing windbreaks to prevent wind erosion, directly aligning with the standard of comparing solutions to Earth's changes.
2-ESS2-2
Secondary
Develop a model to represent the shapes and kinds of land and bodies of water in an area.Reason: Model-building is a key part of testing windbreak designs, requiring students to conceptualize land and water shapes.
2-ESS2-3
Supporting
Obtain information to identify where water is found on Earth and that it can be solid or liquid.Reason: Though not directly about windbreaks, understanding water's forms can help in broader understanding of Earth materials.

Entry Events

Events that will be used to introduce the project to students

Storytime with a Meteorologist

Arrange a story-reading session where a local meteorologist shares tales about dramatic weather changes and the importance of land conservation. This narrative approach connects students to real-world weather events, sparking their interest in designing windbreaks for environmental protection.

Wind Erosion in Action

Kick off the project with a live demonstration where students witness the power of wind blowing loose sand across a flat surface. Use a fan to simulate strong wind conditions and discuss the effects of wind erosion, inspiring students to think about how windbreaks could mitigate this process.
