SAASTE Science/Ideas for Class Projects

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.
