Project+Examples

The following ideas have been put forward by teachers at IB workshops.

CONCRETE
 * Biology: Medical effects of dust.\
 * Chemistry: Purity of limestone, additives, chemical attack, the setting process.
 * Design Technology: Composites, choice of material, reinforcement.
 * Environmental Systems: Impact of extracting and using sand, cement, aggregate.
 * Physics: Strength, composite theory, thermal properties.

EFFECT OF CAFFEINE ON PHYSICAL PERFORMANCE
 * Biology: Effect on respiration, blood pressure, heart rate, reflex time and balance.
 * Chemistry: Sources and composition of caffeine, determining caffeine levels in these sources.
 * Physics: Measuring power output (stair climbing, cycles, speed rotations).

BATS
 * Biology: Population size, feeding habits, food chains, diseases.
 * Chemistry: Fertilizer, e.g. guano (nitrate, phosphate, decomposition, pH), odour.
 * Design Technology: Capture methods, marking.
 * Physics: Echo location, number of bats, exit data from roost.

SCIENCE IN THE THEATRE
 * Biology: Reducing stress in performers.
 * Chemistry: Creating safe special effects.
 * Design Technology: Designing new sets, lighting.
 * Environmental Systems: Improving air quality.
 * Physics: Creating new lighting effects.
