<h1>🧱 Sink or Float?</h1>
<h2>Week 7 • Wednesday • Testing Solids in Water</h2>
<h3>📖 Reading Time</h3>
<div class="reading-box">
<p>Drop a rock in water. It sinks to the bottom! Drop a cork in water. It floats on top! Sinking and floating are properties of solids.</p>
<p>Heavy things do not always sink. A giant ship is very heavy, but it floats. Its shape helps push water away. Small things do not always float. A tiny coin sinks fast!</p>
<p>Scientists make predictions before testing. Then they test each object the same way. Today you will predict which solids sink or float. Then you will test them and record your results.</p>
</div>
<h3>✏️ Quick Questions</h3>
<p>1. What happens when you drop a rock in water?</p>
<div class="answer-line"></div>
<p>2. Do heavy things always sink? Give an example.</p>
<div class="answer-line"></div>
<p>3. What do scientists do before they test?</p>

</div>
<h3>⚠️ Safety</h3>
<div class="safety-box">
<p>Ask a grown-up before putting anything in water. Do not test electronics, books, or anything that should stay dry. Wipe up splashes right away. Never taste the test water.</p>
</div>
<h3>🔬 Experiment: Sink or Float Test</h3>
<div class="activity-box">
<p style="margin-bottom:3px;"><strong>You need:</strong> a big bowl of water, a towel, and six small solids. Try a coin, a cork or crayon, a spoon, a plastic toy, a rock, and a leaf.</p>
<p>Predict first! Then gently drop each object in the water. Watch what happens. Record your results on page two.</p>
</div>

<h3>📊 Sink or Float Chart</h3>
<p style="font-size:10.5px; color:#555;">Circle your prediction. Then circle what really happened.</p>
<table>
<tr><th>Object</th><th>My prediction</th><th>Result</th></tr>
<tr><td>Coin</td><td>sink / float</td><td>sink / float</td></tr>
<tr><td>Cork or crayon</td><td>sink / float</td><td>sink / float</td></tr>
<tr><td>Metal spoon</td><td>sink / float</td><td>sink / float</td></tr>
<tr><td>Plastic toy</td><td>sink / float</td><td>sink / float</td></tr>
<tr><td>Rock</td><td>sink / float</td><td>sink / float</td></tr>
<tr><td>Leaf</td><td>sink / float</td><td>sink / float</td></tr>
</table>
<h3>📊 Solid Property Cards</h3>
<p style="font-size:10.5px; color:#555;">Pick two objects you tested. Fill in a property card for each.</p>
<table>
<tr><th>Property card 1</th><th>Property card 2</th></tr>
<tr><td>Object: __________________</td><td>Object: __________________</td></tr>
<tr><td>Hard or soft? ______________</td><td>Hard or soft? ______________</td></tr>
<tr><td>Heavy or light? ____________</td><td>Heavy or light? ____________</td></tr>
<tr><td>Sink or float? _____________</td><td>Sink or float? _____________</td></tr>
</table>
<h3>🎨 Drawing: My Test Bowl</h3>
<p style="font-size:10.5px; color:#555;">Draw your bowl of water. Show the floaters on top and the sinkers on the bottom.</p>
<div class="draw-box" style="height:100px;"></div>

<h3>✏️ Write About Your Test</h3>
<p>1. Which object surprised you the most? Why?</p>
<div class="answer-lines-triple">

<h3>🧠 Design Challenge: Make a Sinker Float</h3>
<div class="activity-box">
<p>Pick one object that sank. Can you make it float? Try resting it on a plastic lid or foil boat. Draw your idea below.</p>
</div>
<div class="draw-box" style="height:90px;"></div>
<p>Did your idea work?</p>
<div class="answer-line"></div>
<h3>📓 Science Journal</h3>
<div class="activity-box">
<p>Write today's date in your journal. List your sinkers and your floaters. Write one sentence about your biggest surprise.</p>
</div>
<h3>🏠 Home Activity</h3>
<div class="activity-box">
<p>At bath time, test one new bath toy. Predict first, then test. Tell your family if your prediction was right.</p>
