• Nature is a master builder! A wasp nest, for example, is strong, light, waterproof, and easy to make larger. It is made of materials that are easy to find and use again.• Humanbuilt structures can be made from natural or human made materials.• Some materials, like aluminum, are recyclable. This means they can be made into new products. • Other materials, like wood, can be replaced by new growth. • Some materials, like plastic, are reusable. They can be used more than once.

The aluminum in this pop can can be recycled and made

into new products.

For Teachers

Goal: To find out what materials are recyclable, renewable, and reusableOutcome SM3.1: Investigate properties of materials and methods of joinery used in structures. Indicators:a. Identify problems to be solved related to the properties of materials in structures (e.g., What is the purpose of the structure? What materials are appropriate for constructing the structure? What are appropriate methods of joinery?).b. Examine the properties of materials used in structures (e.g., beaver lodge, bird nest, wasps’ nest, honeycomb, ant hill, tipi, house, marionette, circus float, umbrella, ladder, bridge, earthlodge, quinzhee, drink can, hockey puck, playground equipment, and toys).i. Examine the suitability of using recycled materials to construct structures (e.g., tires as highway surfacing, and reclaimed lumber or straw bales for houses).

The Magic Tunnel

Are the structures listed below made from reusable, recyclable, or renewable material?

Drag the labels through the magic tunnel to see if you are correct!

pop canrecyclable

ant hillrenewable

fleece jacket recyclable, reusable

wigwamrecyclable,renewable, reusable

wooden houserenewable, reusable

paper printed on one side reusable, recyclable, renewable

plastic waterbottle reusable, recyclable

For Teachers

Students decide whether each of the structures listed on the left is made from reusable, recyclable, or renewable materials. Once they have made their guess, they can drag the word through the magic tunnel and onto the yellow side to reveal the answer.

Students can review the terms reusable, recyclable, and renewable on page 71 of the student book.

With a partner, brainstorm some structures that you have seen at home or at school. What materials are these structures made of? Are these materials recyclable, reusable, or renewable? Discuss these questions with your partner, and complete the table below. One example has been done for you.

Structure Made From Reusable Recyclable Renewable

water bottle plastic yes yes no

• your notebook• a pencil

For Teachers

This activity is based on the Work On It activity on page 71 of the student book.

Have students copy and complete the chart in their notebooks. Then, ask students to take turns adding information to the table on the interactive whiteboard.

Structures can be made from natural materials, humanmade materials,or a combination of both. Use the Venn diagram to compare and contrastthe wigwam and brick house below.

Wigwam House

made from all natural materials

constructed with little waste

materials are wellsuited for the structure

constructed with more waste

uses some nonrenewable materials

uses some humanmade materials

For Teachers

Invite students to drag the descriptions onto the Venn diagram. Answers are shown on the following page.

Invite discussion and debate if students disagree with the answers as shown.


7




Which structure would you rather live in? Why? Discuss your answerwith a partner.

Wigwam House

constructed with little waste

materials are wellsuited for the structure

constructed with more waste

uses some nonrenewable materials

uses some humanmade materials

made from all natural materials

For Teachers

Discuss:Invite discussion and debate if students disagree with the answers as shown.

Have students discuss the question with a partner.Answers:Students might prefer the wigwam for its environmental sustainability, familiarity, tradition,novelty, or similarity to camping. Theymight prefer the brick house for its size, comfort,familiarity, or durability.

What do you think is most important part of the responsible use of materials? Raise your hand to vote for Reduce, Reuse, or Recycle.Tally the votes in the table below.

Reduce Reuse Recycle

AnswerReduce is the most important of the three Rs. When we reduce the amount of material we consume, we create less waste.

For Teachers Ask students to vote by show of hands to see what they

think is the most responsible "R". You or a student can tally votes on the interactive whiteboard.

To reveal the answer, pull the grey screen shade down.

AnswerThe best choice is to reduce. Reducing the amount of materials we consume will prevent waste from being generated.

Students may think recycling is the most important part of the responsible use of materials. Unfortunately, recycling materials takes energy as well as other resources. This makes it the least valuable of Reduce, Reuse, Recycle.

If you need to reset the screen shade, touch the Show/Hide Screen Shade button, then drag the screen shade to the bottom of the table.
