Reusing Limited Materials

Supplied materials

• Paper and pencil; drawing or spoken answers are welcome.
• Topic notes: Reuse: use the same object again. Repair: fix an object so it can continue serving its purpose. Recycle: process discarded material into material for another product. Reduce: use less material in the first place.
• Original exercise cards: A fictional class uses the same storage box next week. / A fictional worker mends a torn bag. / A fictional facility processes collected paper into new paper. / A fictional class chooses a design using one sheet instead of two. / Someone replaces a broken chair leg. / A facility melts collected metal for new products. / A group avoids unnecessary packaging. / A person refills the same reusable bottle.

Learn the idea

Resources are limited. Reusing an object means using it again; repairing means fixing it. Recycling processes material into new material or products. Reducing means using less in the first place. These actions can overlap, but match the action directly stated in each fictional card.

Reuse: use the same object again. Repair: fix an object so it can continue serving its purpose. Recycle: process discarded material into material for another product. Reduce: use less material in the first place.

Look for using an object again, fixing it, processing old material into a new product or using less material. Ask an adult to read the notes and cards aloud. Point, draw or say your answer.

1. Ask an adult to read the four notes. Find the words Reuse, Repair, Recycle, Reduce.
2. Look for using an object again, fixing it, processing old material into a new product or using less material.
3. Read the worked answer. Then try the other cards and explain which words helped you choose.
4. Point to, draw or say two different examples: one for Reuse and one for Repair. Explain how their clues differ.

Take it further

New card: “A person refills the same reusable bottle.” Match it with a note, then point to or say the words that helped. Check: The card says: “A person refills the same reusable bottle.” That matches Reuse. Reuse is use the same object again.
