Quiz With their talk partners, the children are to go through the quiz at the end of the presentation and answer the questions. Formative Assessment Forms Students are to complete these forms where present. Assessment Trays Ask the children to place their Handouts, notebooks, Formative Assessment Forms, Investigation Sheets, into either the Discover tray or Explorer tray * Explain that the green tray means that the learner has understood the lesson well, and that the red tray means that the learner needs more time to practise. * use whichever colours of tray you have in stock, or prefer to use for this. Children to take interactive Assessment Quiz to test lesson comprehension.

Assessment

Questions to Ask During the Lesson

Explain how the properties of materials are related to their uses and select appropriate materials.

Teacher Mastery

Most of the glass we use is soda-lime glass, made by heating a mixture of sand, sodium carbonate, and limestone. Borosilicate glass, made from sand and boron trioxide, melts at higher temperatures than soda-lime glass.

Clay ceramics, including pottery and bricks, are made by shaping wet clay and then heating in a furnace.

Curriculum Fields

National Curriculum

Compare quantitatively the physical properties of glass and clay ceramics, polymers, composites and metals. Explain how the properties of materials are related to their uses and select appropriate materials.

Working Scientifically Skills

Communicating the scientific rationale for investigations, including the methods used, the findings and reasoned conclusions, using paper-based and electronic reports and presentations
