Hoang‚ Sophia Candidate # 001430096 Artist Statement I create art because this passion and curiosity has been with me ever since I was a toddler‚ running around and doodling on any surface possible. In this course I wanted to learn techniques that would help me improve my style. I wanted to broaden my creativity by creating abstract works and designing dresses that mimic Alexander McQueen’s. And also to learn new mediums to create mixed media art because I find those artworks to be unusual

Beverly Hearst IB SL Physics Rate of Vaporization Design Lab Research Question: How does changing the surface area of a sample of water affect the time taken for the water to boil? Background: By changing the containers of the water‚ the surface area of the water is thus being modified as the same volume of water is spread out over smaller or larger surfaces. The measure being compared is the time each sample of water will take before it reaches the boiling point‚ 100 C°. The relationship

Math Studies: Units Project Talha Mirza 1A Gilmartin Dear noble tribe leaders of T-Island‚ I have created a brand-new system of units for us to use in our daily lives called the T-Dog system. You will find this system to be quite useful‚ as it includes six unique units which measure temperature‚ length‚ time‚ weight/mass‚ volume/displacement‚ and currency. By utilizing these units‚ life will be made easier for us. Moreover‚ if it is ever decided to switch to other well-known systems‚ it is
