Many people are fascinated with ancient Egypt. The amazing, unique culture influenced many other civilizations and cultures. If you study the history of math, you will see how this influence included mathematics. Ancient Egypt also lasted an incredibly long time – over 3000 years. According to Egyptologist Bob Brier, “No civilization lasted so long, contributed so much, or repeatedly amazed as did ancient Egypt.”
In this Open Educational Resource activity, students will have the opportunity to learn about ancient Egyptian numerals and basic arithmetic. For motivation, the setting is a scribal school with each student using a clipboard, paper, and fine point black marker to simulate a board, papyrus, and brush with ink. The activity can also be completed on its own without the scribal school setting.

L'objectif de ce module est de présenter les bases du calcul financier, en se focalisant sur le concept central de taux d'intérêt. Les techniques d'intérêt simple et d'intérêt composé sont décrites et appliquées au calcul de la valeur acquise à une date future d’un flux financier payé aujourd’hui (technique de capitalisation). Le principe de l’actualisation visant à déterminer aujourd’hui la valeur actuelle d’un flux futur est ensuite étudié. La prise en compte d’une série de flux financiers échéants à diverses dates conduit à la notion d’annuité dont on calcule les valeurs actuelles et acquises. Ce module introductif à la mathématique financière sera suivi d’autres modules consacrés à des problématiques pratiques de la finance (amortissement d’un emprunt hypothécaire, calcul du rendement d’un projet d’investissement, …).

Students will have the opportunity to work in groups and investigate the effects of an “oil spill” in a water body. In a simulated “ocean” (a pan of water), students will drop a small amount of oil into the water and see the effects and interaction. In an introduction to the workshop, students discuss sources of pollution and oil contamination in water bodies – from point sources (tanker spills) and non-point sources (vehicle run-off). A brief discussion on preventing and cleaning up oil contamination will lead into the activity, in which the students will use a variety of materials to see what method works best for recovering the most oil from the water.

Students will develop a proposal explaining which materials and procedures work best for cleaning up an oil spill. Students will also create a presentation to share their proposal.
