Students create and test sheltersCopyright http://blogs.abc.net.au/.a/6a00e0097e4e68883301901e444b5a970b-pi
Student groups use kite string and wax paper shaped as leaves to build shelters to protect them from the rain. Then they test the shelters for durability and water resistance.
Through this lesson and activity, student teams complete the engineering design process used by practicing engineers including constructing and testing their designs. When faced with a challenge, engineers evaluate various potential solutions and select one that best meets the criteria for success.They build and test it, revising it until an acceptable solution is achieved.
- Learn about the characteristics, and make qualitative observations, of plants found in the Amazon rainforest.
- Design and build a model shelter from "local" materials.
All living things share similar characteristics, but they also have differences that can be described and classified
Grade 4
Do you agree with this alignment?Each plant or animal has different structures or behaviors that serve different functions
Grade 2

Models are used to communicate and test design ideas and processes.

3-5-ETS1-1 Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
Grades 3-5
This resource focuses on the following Three Dimensional Learning aspects of NGSS:
Science & Engineering Practices- Define a simple design problem that can be solved through the development of an object, tool, process, or system and includes several criteria for success and constraints on materials, time, or cost.Do you agree with this alignment?
Disciplinary Core Ideas- Possible solutions to a problem are limited by available materials and resources (constraints). The success of a designed solution is determined by considering the desired features of a solution (criteria). Different proposals for solutions can be compared on the basis of how well each one meets the specified criteria for success or how well each takes the constraints into account.Do you agree with this alignment?
Crosscutting Concepts- People's needs and wants change over time, as do their demands for new and improved technologies.Do you agree with this alignment?

3-5-ETS1-2 Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.

This resource focuses on the following Three Dimensional Learning aspects of NGSS:
Science & Engineering Practices- Generate and compare multiple solutions to a problem based on how well they meet the criteria and constraints of the design problem.Do you agree with this alignment?
Disciplinary Core Ideas- Research on a problem should be carried out before beginning to design a solution. Testing a solution involves investigating how well it performs under a range of likely conditions.Do you agree with this alignment?
- At whatever stage, communicating with peers about proposed solutions is an important part of the design process, and shared ideas can lead to improved designs.Do you agree with this alignment?
Crosscutting Concepts- Engineers improve existing technologies or develop new ones to increase their benefits, to decrease known risks, and to meet societal demands.Do you agree with this alignment?

Each group needs:
- 1 sheet of wax paper, approximately 12-in x 12-in
- Amazon Plant Leaves Template
- kite string, 2 feet
- 45+ hole punch reinforcers (1 sheet) or masking tape cut into small pieces approx. ¼" x ¼"
- 5 popsicle sticks
- 1 Dixie Cup or small bowl
- Student Guide Worksheet
Each student needs:
- 1 cake tray
- 1 clay or sticky putty packet
Refer to the storyline provided in the Introduction/Motivation section of the associated lesson 3.
- Give groups a time limit for setup in each step of testing their shelters.
- Collect any leftover wax paper, which limite students to use only the leaves they cut out.
Worksheets: Have student groups complete and hand-in activity worksheets.
Prior to building the shelters, have students cut out some of the leaves to scale (using green butcher paper or similar) to help them understand how large some of these leaves really are. You might decorate your classroom in an Amazon rainforest theme, or even have the class construct a life-sized shelter using large dowel rods, string, tape and the paper cut-outs. Students remember the variety of plants better if they see how large the plant leaves can grow.
