Lesson 141: Safe uses of materials

Objective

I can name common materials like glass, metal, plastic, wood, and water. I can tell safe ways to use these materials and say what we should not do around things that are sharp, hot, or easy to break.

Materials

• Safe classroom or home objects (plastic cup, wooden spoon, metal spoon, soft toy)
• Pictures of glass bottles, windows, scissors, hot pans, cleaning bottles
• Paper for drawing a simple safety poster
• Pencil, crayons, or markers

Mini-lesson — Using materials safely

Guided Practice — Look at objects and talk about safety

You will look at real objects or pictures and talk about how to use them safely. Use simple words to say what is safe and what is not.

1. Gather objects: With an adult, choose safe objects like a plastic cup, metal spoon, wooden spoon, and soft toy. Use pictures for glass and cleaning bottles.
2. Name the material: For each object ask, "Is this glass, metal, plastic, wood, or water?"
3. Ask about safety: Say, "How do we use this safely?" For example, "We drink from the glass cup but do not run with it."
4. Talk about unsafe ideas: Think of one unsafe thing, like running with a glass bottle, then explain why it is unsafe.
5. Make a rule sentence: For each object, say one rule, such as "Walk with glass" or "Do not touch hot pans".
6. Use the tracing pad: Choose words like glass, metal, plastic, or safe from the dropdown and trace them slowly. Say the word as you write.
7. Finish with a sentence: Write one sentence such as "Glass can break, so we walk with it" or "Scissors are sharp, so we cut only paper".

Tip: As you trace the words, tell a short safety rule, like "Glass can break" or "Ask an adult before using sharp things".

Practice 1 — Safe or unsafe?

Read or listen to each action. Decide if it sounds safe or unsafe. Explain why.

1. Running while holding a glass bottle.
2. Walking slowly with a plastic cup of water.
3. Touching a hot metal pan on the stove.
4. Putting scissors back in the pot or box after using them.
5. Drinking from a clean glass or plastic cup.
6. Playing with cleaning sprays like they are toys.

Make two columns on your paper: "Safe" and "Unsafe". Write each action in the correct column and add a few words like "could cut" or "walks slowly".

Practice 2 — Materials in my home or classroom

Look around your home or classroom. Find a few objects and think about what they are made of and how to use them safely.

1. Choose three to five objects, such as a cup, chair, window, book, and toy.
2. For each object, write its name and what it is made of (glass, metal, plastic, wood, or mixed).
3. Next to each one, write one safety rule. For example: "Glass window — do not push or hit" or "Wooden chair — sit properly, do not stand on it".
4. Share your list with an adult and ask if they have more safety rules for those objects.

Practice 3 — Design a safety poster

Create a simple safety poster about using materials safely.

1. At the top of your paper, write a title such as "Safe Uses of Materials" or "Stay Safe with Glass and Metal".
2. Draw two or three pictures that show safe actions, like walking with a glass or putting scissors away.
3. Under each picture, write a short rule sentence, such as "Walk with glass" or "Ask an adult for help".
4. Color your poster and hang it in a place where you will see it and remember the rules.

Quick Check — Safe uses of materials

Answer each question about materials and safety. Think about what things are made of and how we should use them.
