Ms Vines and Mrs Wentzel

Year 8 Element & Compound Research

PowerPoint Presentation

You are required to use PowerPoint to do research on a selected Element or Compound. Choose one from the list.

Your research needs to include the following content:

|1 |Front page – your Element/Compound’s name, image |ACSU 152 |

|2 |Appearance of the element/compound – colour, hard or soft, physical features, state of matter, how |ACSU 152 |

| |is it stored | |

|3 |History of this element/compound – when, who and where this element was discovered, symbol, origins.|ACSHE 134 |

|4 |Atomic structures – number of protons, neutrons, and electrons in an atom. A simple diagram should |ACSHE 152 |

| |be included. Where can this element / the elements of the compound be found on the periodic table? | |

|5 |Occurrence and extraction of the element(s) found in this compound |AC SHE136 |

|6 |Physical properties: a metal or non-metal, melting point (in Celsius only), boiling point, |ACSU 152 |

| |conductivity of electricity, density | |

|7 |Chemical properties: How reactive is this element? Another chemical property of your |ACSU 152 |

| |element/compound | |

|8 |Uses of this element / compound – mention 4 or more uses |ACSU 136 |

|9 |References |ACSIS 148 |

|10 |Presentation |ACSIS 148 |

Tips: You must use PowerPoint and include its key features:

❖ 9 – 12 slides (Max)

-----------------------

By the end of Year 8, students compare physical and chemical changes and use the particle model to explain and predict the properties and behaviours of substances. They identify different forms of energy and describe how energy transfers and transformations cause change in simple systems. They compare processes of rock formation, including the timescales involved. They analyse the relationship between structure and function at cell, organ, and body system levels. Students examine the different science knowledge used in occupations. They explain how evidence has led to an improved understanding of a scientific idea and describe situations in which scientists collaborated to generate solutions to contemporary problems. They reflect on implications of these solutions for different groups in society.

Students identify and construct questions and problems that they can investigate scientifically. They consider safety and ethics when planning investigations, including designing field or experimental methods. They identify variables to be changed, measured, and controlled. Students construct representations of their data to reveal and analyse patterns and trends and use these when justifying their conclusions. They explain how modifications to methods could improve the quality of their data and apply their own scientific knowledge and investigation findings to evaluate claims made by others. They use appropriate language and representations to communicate science ideas, methods, and findings in a range of text types.

Assignment Details

Your task

Your assignment will consist of 2 parts –

TASK 1: Research Elements and Compounds

(Science Understanding / Science as a Human Endeavour)

You are required to use PowerPoint to do research on a selected Element or Compound. Choose one from the list provided. Ensure you add in all the sections required. Use your rubric to ensure you’ve covered all areas.

TASK 2: Physical and Chemical Changes

(Science Inquiry Skills)

You are required to complete 8 practicals, determine if physical or chemical changes occurred and what the evidence is to support your findings.

DUE DATES:

Week 4 & 6
