IDEAS FOR CLASS PROJECTS[edit]

Water Analysis Project

Water quality testing of certain sectors of the Berg river/Palmiet river

  • Field work -testing skills/analysis (biological/chemical)
  • Out of the classroom experience
  • Sensitize learners -environmental awareness/responsibility
  • Promotes group work
  • Learners formulate hypothesis
  • Learners planning the sequence of activities/design experiments
  • Interdisciplinary approach - biology, geography, physical science, mathematics, history, communication, technology
  • Communication skills-written, verbal, graphical
  • Data analysis and conclusions

Time management is critical when performing such a project. Additional information might be needed beforehand e.g. Topographical maps and information from the local municipality.


Effective Gastric antacids

Comparing the effectiveness of different brands of commercial gastric antacids

  • Identification of a problem
  • Learners formulate hypothesis
  • Literature survey
  • Experiment design
  • Conduct experiment
  • Process skills -observation, time keeping, recording of data, measuring, variable identification and control e.g. temperature, referencing Data presentation
  • Data analysis and conclusions

Fungi development

To investigate the conditions for fungi growth.This can be linked to sell by/use by dates on commercial perishable products.

  • Identification of a problem
  • Learners formulate hypothesis
  • Literature survey
  • Experiment design
  • Conduct experiment
  • Process skills -observation, time keeping, recording of data, measuring, variable identification and control e.g. temperature and moisture, referencing
  • Data presentation
  • Data analysis and conclusions

Insulation materials

To investigate the insulation properties of different materials. This can be useful to determine the best way to keep foodstuffs cold or warm.

  • Identification of a problem
  • Learners formulate hypothesis
  • Literature survey
  • Experiment design
  • Conduct experiment
  • Process skills -observation, time keeping, recording of data, measuring, variable identification and control e.g. temperature , referencing
  • Data presentation
  • Data analysis and conclusions

PH -Levels of different brands of commercial soaps

To determine which soaps have the most suitable pH-levels for human use.

  • Identification of a problem
  • Learners formulate hypothesis
  • Literature survey
  • Experiment design
  • Conduct experiment
  • Process skills - observation, time keeping, recording of data, measuring, variable identification and control e.g. temperature, referencing
  • Data presentation
  • Data analysis and conclusions
