<h1>🧱 Solid Superstars: Review and Boat Challenge</h1>
<h2>Week 7 • Friday • Review of Solid Properties</h2>
<h3>📖 Reading Time</h3>
<div class="reading-box">
<p>You are now a solids expert! You know that solids keep their shape. You know solids have properties like hard, soft, rough, and smooth. You tested which solids sink and which float.</p>
<p>Boat builders use what you learned. They pick strong materials that float. They shape the boat to push water away. A wide, hollow shape floats better than a solid lump. That is why a ball of foil sinks faster than a foil boat!</p>
<p>Today you will review solids. Then you will take on a big challenge. You will design and build a boat that floats!</p>
</div>
<h3>✏️ Reading Questions</h3>
<p>1. Name two properties a solid can have.</p>
<div class="answer-line"></div>
<p>2. What kind of shape floats better than a solid lump?</p>
<div class="answer-line"></div>
<p>3. Why does a foil boat float when a foil ball sinks?</p>

<h3>📝 Vocabulary Review</h3>
<p style="font-size:10.5px; color:#555;">Draw a line from each word to its meaning.</p>
<table>
<tr><th>Word</th><th>Meaning</th></tr>
<tr><td>solid</td><td>drops to the bottom of water</td></tr>
<tr><td>property</td><td>stays on top of water</td></tr>
<tr><td>sink</td><td>matter that keeps its shape</td></tr>
<tr><td>float</td><td>something you can observe about an object</td></tr>
</table>

<h3>🔍 Prediction Game: Sink or Float?</h3>
<p style="font-size:10.5px; color:#555;">Circle your prediction for each new object. Test any you can at home!</p>
<table>
<tr><th>Object</th><th>My prediction</th><th>Why I think so</th></tr>
<tr><td>Apple</td><td>sink / float</td><td></td></tr>
<tr><td>Key</td><td>sink / float</td><td></td></tr>
<tr><td>Pencil</td><td>sink / float</td><td></td></tr>
<tr><td>Marble</td><td>sink / float</td><td></td></tr>
<tr><td>Bath sponge</td><td>sink / float</td><td></td></tr>
</table>
<h3>✏️ True or False</h3>
<p style="font-size:10.5px; color:#555;">Write T for true or F for false in each circle.</p>
<div class="tf-item"><span class="circle-box"></span> All heavy objects sink.</div>
<div class="tf-item"><span class="circle-box"></span> A solid keeps its own shape.</div>
<div class="tf-item"><span class="circle-box"></span> Shape can help an object float.</div>
<div class="tf-item"><span class="circle-box"></span> A coin floats on water.</div>
<div class="tf-item"><span class="circle-box"></span> Scientists predict before they test.</div>
<div class="tf-item"><span class="circle-box"></span> Hard and soft are properties of solids.</div>
<h3>📊 Pick the Best Solid for the Job</h3>
<p style="font-size:10.5px; color:#555;">Write the best solid for each job: foil, rock, sponge, or wood.</p>
<table>
<tr><th>Job</th><th>Best solid</th></tr>
<tr><td>Hold down a stack of papers outside</td><td></td></tr>
<tr><td>Shape into a little floating boat</td><td></td></tr>
<tr><td>Soak up water on the counter</td><td></td></tr>
<tr><td>Build a strong birdhouse</td><td></td></tr>

<h3>🧠 Design Challenge: Build a Boat That Floats</h3>
<div class="activity-box">
<p style="margin-bottom:3px;"><strong>You need:</strong> foil or a plastic lid, a bowl of water, and small coins for cargo.</p>
<p>Design a boat that floats. Then test it! Add coins one at a time. How many coins can your boat hold before it sinks?</p>
</div>
<p>First, draw your boat design:</p>
<div class="draw-box" style="height:90px;"></div>
<table>
<tr><th>Test</th><th>My answer</th></tr>
<tr><td>Did my boat float?</td><td>YES / NO</td></tr>
<tr><td>How many coins did it hold?</td><td></td></tr>
<tr><td>What would I change next time?</td><td></td></tr>
</table>
<h3>📓 Science Journal</h3>
<div class="activity-box">
<p>Draw your boat in your journal. Write how many coins it held. Write one thing that would make it even better.</p>
</div>
