Year 8 and 9 Mathematics, Science and Technology

SCIENCE

Term 3

Power

This term we will be investigating Forces and Energy through the concept of Power. There are two units of work: Force and motion (Newtons Laws) and Electricity (static, dynamic, current, voltage, resistors, and parallel and series circuits.

Week 1

This week we focused on what is a force - push, pull, twist, how to represent these forces in diagrams and Newtons first Law of inertia - objects will not change what they are doing unless acted on by another force.  

Homework - Three Science experiments - the force in Newtons - hypothesis, results, conclusions and discussions due  14th April

Term 2

This term we will be investigating Crime through Forensic Science.   There are 5 Units of work:Crime Scene Basics, Power of Evidence, Fingerprinting, Blood Analysis and DNA and Genetics. 
Crime Scence Basics:Crime Scene Basics PowerPoint and Worksheet; Eyewitness Basics PowerPoint and Worksheet; Forensic Science A-Z Challenge Worksheet; Forensics Movie Worksheet: Unit Review PowerPoint and Worksheet. 
Power of Evidence: Power of Evidence PowerPoint and Worksheet; Lip Prints; Impression Evidence (Tyre Tracks PowerPoint and Worksheet); Hair and Fibres (Hair and Fibres PowerPoint and Worksheets, HairLab Worksheet, Hair and Fibre ID Lab Worksheet); Chromatography (PowerPoint and Worksheet); Mystery Powders; Murder and a Meal; Power of Evidence Review PowerPoint and Worksheet.
Fingerprinting: Fingerprinting Basics PowerPoint and Worksheet; Ridgeology PowerPoint and Worksheet; Latent Prints PowerPoint and Worksheet; Unit Review PowerPoint and Worksheet.
Blood Basics: Blood Basics PowerPoint and Worksheet; Bloodtyping PowerPoint and Worksheet; Bloodstain Science PowerPoint and Worksheet; Unit Review PowerPoint and Worksheet.

Assessment

There will be 2 areas of assessment: Science Reports from Laboratory experiments and a Portfolio compiled from inclass worksheets,end of unit quizzes, classroom observation and a DNA activity.

Lesson 10 - The Value of Evidence - Students watched a 'Discovery Education' video on the Value of Evidence with an accompanying worksheet.  Part of their homework is to check their answers on their worksheet with the attached answer key (Page 3 of the attached file).  We then began to look at the scientific process of chromatography.  Within the powerpoint, there are a number of scientific and general English terms and phrases.  Ongoing homework is to identify key words and terms from the information given, copy these words and terms to a glossary in the back of their science notebooks, and use 'Visuwords' (see Lesson 1) to define the words.  Further homework is to peruse the attached powerpoint on chromatography, complete the worksheet distributed in class (copy attached) and become familiar with the upcoming practical laboratory (Thursday's lesson) on paper chromatography.

Lesson 11 - Practical lesson at last!! Students completed the paper chromatography science laboratory.  This is a lab that they could do at home using paper towel instead.  Make sure you use water-based markers though.  Instructions are in the previous powerpoint.  Students have until Sunday 20th February to submit their completed laboratory reports.  Students are to use the headings as outlined in the 'Practical Science Documents' section below.
Lesson 12 - Hair and Fibre Analysis.  In this lesson, we determined characteristics of human and animal hair, as well as natural and synthetic fibres.

Lesson 13 - Fingerprinting Basics - As well as learning the different types of fingerprint patterns, students had a try at taking their own fingerprints and analysing the patterns.  Did you know that on average 60% of the world population have loops, 35% have whorls and the remaining 5% have arches?  We tested this theory with our class and found that 63% had loops, 32% had whorls and 5% had arches.  Go figure!

Week 10 - DNA

This week we move onto DNA and like fingerprints how they are used to eliminate or convict suspects - Practical lesson this Thursday on strawberry DNA - report due Sunday 20.3.11 

Homework  http://www.biotechnologyonline.gov.au/biotechnologyonline/topitems/resources.html  - DNA Profiling work through the activity and solve the two different cases.
