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. 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 Mesothelioma Information Reference
