<p>Mass is how much matter is in something. We can measure this by weighing. So today we will be ...</p>

<div class="center80">
|

|
|
</div>
|
|
<p>You will need:</p>
|
|
<ul>
|
|
<li>Kitchen Scales (for smaller items)</li>
|
|
<li>Bathroom Scales (for larger items)</li>
|
|
<li>Pen and paper</li>
|
|
</ul>
|
|
<p>You can measure using grams (g), kilograms (kg), ounces (oz) or lbs (lb).</p>

|
|
<p>This knife weighs about 75 g (nearly 3 oz)</p>
|
|
<p><b>How did I measure that?</b></p>
|
|
<p>Between <b>0</b> and <b>4oz</b> there are 4 spaces, so each mark means 1oz. The pointer is nearly up to the 3rd mark, which means nearly 3oz.</p>
|
|
<p>Likewise between <b>0</b> and <b>100g</b> there are 4 spaces, so each mark means 25g.<br>
|
|
The pointer is on the 3rd mark, which means 75g.</p>

<p><b>Some ideas of things to measure:</b></p>

|
<li>Bottles (empty or full)</li>
