<span class="Apple-style-span" style="color: black;"><span class="Apple-style-span" style="font-family: inherit;"><span class="Apple-style-span" style="font-size: x-small;">Read the introduction, objectives and theoretical background to the project and then answer the following questions:</span></span></span><br />

</ul>
<div>
<span class="Apple-style-span" style="color: black;"><span class="Apple-style-span" style="font-family: inherit;"><span class="Apple-style-span" style="font-size: x-small;">For The Fastest ball challenge, it revolves around one of Newton's laws, </span></span></span><span class="Apple-style-span" style="line-height: normal;"><span class="Apple-style-span" style="color: black;"><span class="Apple-style-span" style="font-family: inherit;"><span class="Apple-style-span" style="font-size: x-small;">For example, the solution for the impact velocity of a falling object is much easier by energy methods.</span></span></span></span></div>

It also involves on how the molecules in tea work.</span></span></span></span></div>

</ul>
<div>
<span class="Apple-style-span" style="color: black;"><span class="Apple-style-span" style="font-family: inherit;"><span class="Apple-style-span" style="font-size: x-small;">We know that for Newton's law for the fastest ball challenge, the larger the angle, the more potential energy the ball bearing has, and thus have more kinetic energy.</span></span></span></div>
<div>
<span class="Apple-style-span" style="color: black;"><span class="Apple-style-span" style="font-family: inherit;"><span class="Apple-style-span" style="font-size: x-small;"><br /></span></span></span></div>
<div>
<span class="Apple-style-span" style="color: black;"><span class="Apple-style-span" style="font-family: inherit;"><span class="Apple-style-span" style="font-size: x-small;">For the Caffeine extraction, we know that caffeine is used in many drinks, and it can be good or harmful.</span></span></span></div>

<span style="color: #444444;"><span style="line-height: 22px;">We need to accomplish the project requirements and try our best to understand it. </span></span><div>
<span style="color: #444444;"><span style="line-height: 22px;">Hopefully we will also get to ask questions that are related. </span></span><br />
<div>
<span style="color: #444444;"><span style="line-height: 22px;">We want to learn something new at the end of the project,</span></span>
<br />
<span style="color: #444444;"><span style="line-height: 22px;"><br /></span></span><br />

<span style="color: #444444;"><span style="line-height: 22px;">When we actually apply what we have learn to our other projects and real life, it shows that we have understood the lecturer/professor, and have learnt something from it.</span></span></div>
<div>
<span style="color: #444444;"><span style="line-height: 22px;">If we also tell others about what we have learnt, it also shows that you have understood and you know how to explain to others. </span></span></div>

<span class="Apple-style-span" style="color: #444444; font-size: medium;"><span class="Apple-style-span" style="font-size: 16px; line-height: 22px;">We achieved the understanding that things may not be like how it seems. When we were asked to estimate the angle of the slope, we were guessing that it was higher than 40º, but when we had more tries, we realized that our guesses were all wrong, and the ideal and fastest angle was lesser than 40º.</span></span><br />

<li style="border-style: none; margin: 0px 0px 0.25em; padding: 0px; text-indent: 0px;"><span style="font-family: inherit;"> We were taught and were shown the different stages of filtration that has to take place in order to extract caffeine from tea bags. We also learnt the various measures to be taken for safety. We had to wear safety goggles, lab coat and also gloves. My group and I also learnt to manage our time well. We had to try to understand everything by ourselves and also make sure we don't get left behind by everyone else. We had to plan our time really well in order to complete the project.</span></li>
