IDEAS FOR CLASS PROJECTS

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.
