Overview

Read the introduction, objectives and theoretical background to the project and then answer the following questions:

• What main theory or concept is the project based on?

For The Fastest ball challenge, it revolves around one of Newton's laws, For example, the solution for the impact velocity of a falling object is much easier by energy methods.

For the Caffeine extraction, it is based on the solubility of caffeine and other materials in tea to make the experiment work. It also involves on how the molecules in tea work.

• What do you already know about this theory or concept?

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.

For the Caffeine extraction, we know that caffeine is used in many drinks, and it can be good or harmful.

Objectives

What does the group need to accomplish by the end of the project?

We need to accomplish the project requirements and try our best to understand it. 

Hopefully we will also get to ask questions that are related. 

We want to learn something new at the end of the project,

How will you know whether or not your project has been successful?

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.

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. 

Our Achievements (Fastest Ball Challenge)

• What did you achieve by completing this project? When answering this question, consider both personal and academic development.

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.

• Post photographs and videos that you recorded during the project here.

 Our calculations

Our final information

• Describe how the design of your experiment or the design of your product allowed you to achieve the projects desired outcomes.

The slope for the ball bearing cannot be too much, as the ball bearing would just fall and bounce off the track, but also not too low, or the ball bearing does not have enough potential energy to be converted to kinetic energy.

• Identify possible limitations (restrictions) to your project. When answering this question, consider the design of your experiment or the design of your product.

The accuracy of the release of the ball bearing from the start may not always be of hundred percent accuracy same for each round, as there is always a small chance of human error, like accidentally giving the ball bearing a push while releasing it, and not in the other retries and angles.

• Suggest possible improvements that could be made in order to minimize the limitations that you have identified.

Instead of using human hands, prepare a set-up like placing a ruler infront of the ball bearing before releasing, or a machine to release the balls to ensure a fair chance for everyone who is doing that challenge.

Our Achievements (Extraction of Caffeine From Beverages)

• What did you achieve by completing this project? When answering this question, consider both personal and academic development.
•  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.
•  
• Post photographs and videos that you recorded during the project here.
• We didn't bring in our cameras or phones into the lab as we were concerned if it could be contaminated. 
• 
  
• Describe how the design of your experiment or the design of your product allowed you to achieve the projects desired outcomes.
•  The chemicals were to separate the caffeine from all the other elements that are in the tea bags. These helped in the extraction of the caffeine from beverages which in this case is the tea bags.
• 
  
• Identify possible limitations (restrictions) to your project. When answering this question, consider the design of your experiment or the design of your product.
• The caffeine can only be extracted to a certain extend but may still be contaminated. Therefore, the results won't be as accurate but the caffeine extracted can still be clearly seen in a light green powder. 
• 
  
• Suggest possible improvements that could be made in order to minimize the limitations that you have identified.
• Try using different methods to extract the caffeine.
