Summary

In the continuing "Lost in the Amazon" scenario of this unit, students test the shelters they built in this unit's Lesson 3, Activity 1, for durability and water resistance.
This engineering curriculum meets Next Generation Science Standards (NGSS).

Engineering Connection

This lesson and activity provides an opportunity for student teams to complete the engineering design process used by practicing engineers, including constructing and testing their designs. See the related unit's Engineering Connection for further explanation.

Learning Objectives

Design and conduct a scientific experiment by testing model shelters for durability and water resistance.

The Need for Shelter

As part of the continuing adventure scenario for this unit, students build shelters to protect themselves from the rain. After the shelters are built, the class performs durability and waterproof testing on the shelters.

Elementary Lesson
Home, Sweet Home!

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.

Elementary Activity
Physics of the Flying T-Shirt

Students are introduced to the physics concepts of air resistance and launch angle as they apply to catapults. This includes the basic concepts of position, velocity and acceleration and their relationships to one another. They

High School Lesson
Close Encounters of the Polymer Kind

Students explore the basic characteristics of polymers through the introduction of two polymer categories: thermoplastics and thermosets. During teacher demos, students observe the unique behaviors of thermoplastics.

Educational Standards

Each TeachEngineering lesson or activity is correlated to one or more K-12 science, technology, engineering or math (STEM) educational standards.

All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN), a project of D2L (www.achievementstandards.org).

In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; within type by subtype, then by grade, etc.

Materials List

Per Group:

  • 1 Dixie cup or small bowl (as used in Activity 1)
  • 1 cake tray
  • 1 watering can (or cup with holes poked in the bottom of it)
  • 1 container with lid (such as a coffee can)

Introduction/Motivation

Will these shelters keep us dry in the rainforest? Will these shelters be sturdy enough to protect us? How can we test them to see if they are durable and rain resistant? (As guided by the worksheet, proceed to work together as a class to design an experiment to test the shelters.)

Procedure

  • Discuss with students a good way to test the durability of the shelters.
  • Give groups a time limit for setup in each step of testing their shelters.

Example Test

  • After the shelters have been built, fold them.
  • Put the folded shelters in a container (coffee can) and shake the container to simulate walking through the rainforest.
  • Remove the shelter from the container and set it up on the cake tray with the Dixie cup inside.
  • Using the watering can, pour water onto the shelter.
  • Draw a line and number at the level of water on the cup. Measure the amount of water that ran into the cup and record this amount on a data sheet.
  • Repeat steps 1-5 of this test five or six times to represent five or six nights.
