The Project

1. Background and context: I recently witnessed my mum working with a calculator, whilst having a hot cup of tea with a biscuit. She was frustrated that her biscuit kept dissolving and breaking off into her tea. This led me to think about developing a tool whereby there's a calculator that does it all, i.e, a standard scientific calculator combined with additional features that a) works out optimal biscuit dunking time in hot beverages, and b) also circles calculator - for mathematicians who are working on geometry. 2. Developing my tool: I had already started to make a calculator using python, but knew that to make a website, I must use Html, JavaScript and CSS. I built up my knowledge on JavaScript using Khan academy and we started our html unit in school. We also learnt how to use CSS in school in web pages. I therefore used all of my learning to develop my tool. 3. Features of the tool: • A "biscuit calculator" that works out the optimal dunking time of biscuits in hot beverages and the time when the biscuit dissolves into the hot beverage. • A circles calculator (where you type in the radius as input and select area or circumference using the drop down menu then click calculate). • A scientific calculator for regular use. 4. Feedback and evaluation: I asked friends and relatives for their feedback on my calculator tool. The two areas of feedback received were: a. that I should not allow a negative radius for the circles calculator as that would not be possible. b. the "Ans" button is not yet functional. Both of these areas are still a work in progress and are yet to be fixed. Positive feedback that I received: a. the interface of my calculator is user friendly and in keeping with calculators that people are used to using. b. the additional circles and biscuit features were innovative and user friendly.
