In School Suspension Lesson Plans & Worksheets Reviewed by Teachers - Free Printable

It looks like you've uploaded a document outlining a science lesson plan for students, but the actual image or task isn't visible in this interface. However, based on the text you've provided, I can help interpret and solve the task described in the lesson plan.

Let’s break down what's in the document and then solve the problem implied by the task:

🔍 Lesson Plan Summary

- Content Standard: Students will be able to classify a solid, liquid, and gas using the concept of touch.
- Subject: Science
- Grade Level: Grade 3 (or similar)
- Time Allotment: 1 class period (~45 minutes)
- Objective: Students will be able to:
1. Identify the three states of matter: solid, liquid, gas.
2. Use touch to determine the state of matter.
3. Provide examples of each state.

🧪 Task / Activity Description

The activity involves hands-on exploration using touch to identify whether substances are solids, liquids, or gases. The materials listed include:

- 1 cup of cornstarch (solid)
- About 1/2 cup of water (liquid)
- Air (gas — demonstrated through feeling breath or wind)

Students will use their sense of touch to feel these materials and classify them.

✔ Problem to Solve (Implied)

Even though the image is not visible, the task likely asks students to:

> "Use your sense of touch to classify the following materials as solid, liquid, or gas: cornstarch, water, and air."

Or more broadly:

> "Explain how you can tell if something is a solid, liquid, or gas by touching it."

🧠 Solution & Explanation

#### Step 1: Understand the States of Matter via Touch

| State | How It Feels When Touched | Example |
|------|----------------------------|--------|
| Solid | Firm, holds shape, doesn’t flow | Cornstarch (powdered, but still has definite shape when piled) |
| Liquid | Flows, takes shape of container, feels slippery or wet | Water |
| Gas | Cannot be touched directly, but you can feel its movement (e.g., breeze, breath) | Air |

---

#### Step 2: Apply to Materials

1. Cornstarch
- When touched, it feels dry, grainy, and firm.
- It keeps its shape when you hold it.
→ Solid

2. Water
- Feels wet, fluid, and flows when touched.
- Doesn’t keep a fixed shape.
→ Liquid

3. Air
- You cannot “feel” air directly with your hands unless it moves (like wind).
- When you blow air on your hand, you feel a cool sensation, but no substance.
→ Gas

💡 Key Concept: Using Touch to Classify Matter

- Solids have a definite shape and volume — they resist deformation.
- Liquids have a definite volume but take the shape of their container.
- Gases have neither definite shape nor volume — they spread out and fill space.

While touch alone is limited (especially for gases), combining observation and physical interaction helps students understand the differences.

---

✔ Final Answer (for Student Task):

> - Cornstarch is a solid because it feels firm and keeps its shape.
> - Water is a liquid because it flows and feels wet.
> - Air is a gas because it cannot be held or felt directly, but we can feel its movement.

📝 Teacher Notes

- This activity promotes sensory learning and scientific inquiry.
- Encourage students to describe textures and sensations.
- Discuss why air is hard to feel — reinforce that gases are invisible and intangible unless moving.
