There are three broad subject-specific aims in natural sciences that relate to the purposes of learning science: doing sciences; knowing the subject content and making connections; and understanding the uses of science.<sup>9<\/sup><\/p>\n<p>The teaching and learning of natural sciences involves the development of a range of process skills that may be used in everyday life, in the community and in the workplace:<\/p>\n<ul>\n<li>Accessing and recalling information\u2014Using a variety of sources to acquire information, and to remember relevant facts and key ideas and build a conceptual framework<\/li>\n<li>Observing\u2015Noting objects, organisms and events in detail<\/li>\n<li>Comparing\u2015Noting similarities and differences between things<\/li>\n<li>Measuring\u2015Using measuring instruments<\/li>\n<li>Sorting and classifying\u2015Applying criteria in order to sort items into a table, mind map, key, list, or other format<\/li>\n<li>Identifying problems and issues\u2015Articulating the needs and wants of people in society<\/li>\n<li>Raising questions\u2015Thinking of and articulating relevant questions about problems, issues, and natural phenomena<\/li>\n<li>Predicting\u2015Stating, before an investigation, what you think the results will be for that particular investigation<\/li>\n<li>Hypothesizing\u2015Putting forward a suggestion or possible explanation to account for certain facts<\/li>\n<li>Planning investigations\u2015Thinking through the method for an activity or investigation in advance<\/li>\n<li>Doing investigations\u2015Carrying out methods using appropriate apparatus and equipment, and collecting data by observing and comparing, measuring and estimating, sequencing, or sorting and classifying, sometimes repeating an investigation to verify the results<\/li>\n<li>Recording information\u2015Recording data from an investigation in a systematic way, including drawings, descriptions, tables, and graphs<\/li>\n<li>Interpreting information\u2015Explaining what the results of an activity or investigation mean (this includes reading skills)<\/li>\n<li>Designing\u2015Showing (e.g., by drawing) how something is to be made, taking into account the design brief, specifications, and constraints<\/li>\n<li>Making\/constructing\u2015Building or assembling an object using appropriate materials and tools and using skills such as measuring, cutting, folding, rolling, and gluing<\/li>\n<li>Evaluating and improving products\u2015Using criteria to assess a constructed object, and then stating or carrying out ways to refine that object<\/li>\n<li>Communicating\u2015Using written, oral, visual, graphic, and other forms of communication to make information available to other people<\/li>\n<\/ul>\n<p>In the Natural Sciences curriculum, the following knowledge strands are used as a tool for organizing the content of the subject: Life and Living; Matter and Materials; Energy and Change; and Planet Earth and Beyond. The following is a summary of the learning outcomes and assessment standards that students are expected to have attained in science in the Intermediate and Senior Phases:<\/p>\n<ul>\n<li>Life and Living\n<ul class=\"subitem\">\n<li>Intermediate Phase (Grades 4 to 6)\u2014Explain how plants make their own food (photosynthesis); sort food into the four nutrient groups; describe a balanced diet; process food in some way; describe an ecosystem; elaborate on feeding relationships (food webs)<\/li>\n<li>Senior Phase (Grades 7 to 9)\u2014Identify, describe, and state the function of the basic components of plant and animal cells; draw and label a generalized plant and animal cell; explain the relationship between cells, tissues, organs, and systems; list the systems dealt with, and state the purpose and main components of each;

demonstrate open and closed circuits with the use of a switch; distinguish between conductors and insulators in a range of materials; trace the electrical energy in a sequence from an appliance, such as from your television set to the coal-fired power station and back to the original source, the sun; explain how fossil fuels such as coal are formed; determine which appliances use more energy and explain why this is so<\/li>\n<li>Senior Phase (Grades 7 to 9)\u2014Explain and demonstrate the two broad groups of forces;<br \/>\ndemonstrate and explain the similarities and differences between gravitational, magnetic, and electrostatic forces; make a table of the differences between mass and weight; give the scientific explanation of how lightning occurs; construct a simple cell to provide electrical energy from chemical energy; measure voltage across resistors and the current through them; name advantages and disadvantages for series and parallel circuits; draw and interpret various circuit diagrams; distinguish between series and parallel circuits in the wiring of the home, cars, and toys and explain the differences;
