Group of 3 Students: CHE: Shuttlecock - What is the volume of this shuttlecock? The plan is to model using compound prisms and sphere then to compare the calculations with the actual volume. To find the actual volume we will submerge the shuttlecock in water and measure the water displaced.
Group of 2 Students: MC: Polygon Person - Can we make a polygon person with an area of 100 square centimeters? We will guess the perimeter before we start, then compare our guess with the actual perimeter.
Group of 3 Students: LJK: Capacity of a yogurt container.
Group of 5 Students: ABABA: Polygon people.

Problem: How long would 9x last in P9 if all the windows and doors were closed and it was airtight?
Plan: Measure the room dimensions, calculate the volume of air. Research about oxygen. Make calculations in order to answer the question.
Measure: Width, Length and Heights of P9
Calculate:
- The average adult, when resting, inhales and exhales about 7 or 8 liters of air per minute.
- We have 32 people and 60 minutes.
- 20% of air is oxygen, but people use 25% of this, they exhale 15% Oxygen.
- We will simplify the equation by assuming 5% of the air inhaled is used Oxygen.
- Volume of Oxygen used by 9x in one lesson: 7 liters * 60 minutes * 5% * 32 people = 672 liters
- Estimated Volume of Oxygen in the room at the start of the lesson: width*height*length*20% = 72 cubic meters.
- Convert 72 cubic meters to litres = 72,000 liters.
Conclude:
- There is 72,000 liters of Oxygen in P9.
- 9x uses roughly 672 litres of oxygen per hour.
- We would last 107 hours. As the concentration of oxygen in the air reduces we would start to feel unwell.
