<h1>✋ Hard, Soft, Rough, Smooth</h1>
<h2>Week 3 • Monday • Exploring Surface Properties</h2>
<h3>📖 Reading Time</h3>
<div class="reading-box">
<p>Last week you learned about properties. This week we look closer at four important ones: hard, soft, rough, and smooth.</p>
<p>Hard and soft tell us what happens when we press on a material. A hard material does not squish. Press on a rock. It stays the same! A soft material squishes or changes shape. Press on a marshmallow. It squashes down.</p>
<p>Rough and smooth tell us about the surface of a material. The surface is the outside part we touch. A rough surface has bumps you can feel. A smooth surface feels flat and even.</p>
<p>Here is a tricky idea: a material can be hard AND smooth, like glass. It can be soft AND rough, like a scratchy wool sweater. Today you will explore surfaces like a scientist!</p>
</div>
<h3>✏️ Reading Questions</h3>
<p>1. What happens when you press on a soft material?</p>
<div class="answer-line"></div>
<p>2. What do we call the outside part of a material we touch?</p>
<div class="answer-line"></div>
<p>3. Name something that is hard and smooth.</p>
<div class="answer-line"></div>
<p>4. Can a material be soft and rough at the same time? Give an example.</p>

<h3>🔍 Investigation: Touch-and-Tell Mystery Bags</h3>
<div class="activity-box">
<p><strong>You need:</strong> a bag and a grown-up to put 4 objects inside.</p>
<p>Do not peek! Feel each object inside the bag. Circle the properties. Then guess what it is.</p>

<table>
<tr><th>Object</th><th>Circle what you feel</th><th>My guess</th></tr>
<tr><td>1</td><td>HARD / SOFT ROUGH / SMOOTH</td><td></td></tr>
<tr><td>2</td><td>HARD / SOFT ROUGH / SMOOTH</td><td></td></tr>
<tr><td>3</td><td>HARD / SOFT ROUGH / SMOOTH</td><td></td></tr>
<tr><td>4</td><td>HARD / SOFT ROUGH / SMOOTH</td><td></td></tr>
