Lesson 2: How do forensic scientists investigate a crime scene?
Learning objectives
By the end of this lesson you will be able to: • sequence the different activities that take place at a crime scene • use your judgement to compare the significance and reliability of evidence that can be collected.
The crime scene
In groups: • Watch the video of the crime scene again. • Write down as many significant observations as you can on post-it notes. • Discuss how you think the theft may have occurred.
Crime scene procedures
What is good forensic procedure?
In pairs: • Match the photographs of the crime scenes and their statements. • Describe the importance of the activities. • Place the photographs in order to show the sequence of the activities. • Explain why you have put the activities in order.
Every contact leaves a trace
Examine the film of the crime scene again. This time: • Identify relevant facts about the scene, possible human contact points and suggest human traces that may have been left behind. • Write down your observations in the Evidence Collection File. • Suggest how the theft might have been made.
Lesson 3: Designing a forensic kit storage system
Learning objectives
By the end of this lesson you will be able to: • create design ideas by simple modelling using plans and 3D paper models.
Designing a forensic kit storage system
Design brief
To design and make a forensic kit storage system for the purpose of holding a range of equipment for collecting and analysing evidence.
Designing a forensic kit storage system
Specification
• • • • • each item has its own place in the box each item is easy to find each item is easy to remove each item is easy to return each item stays in that place when the box is being moved • the collected evidence does not get mixed up with other items.

Lesson 4: Making a forensic kit storage system
Learning objectives
By the end of this lesson you will be able to: • develop your design of the forensic kit storage system
• construct a finished product
• test the storage system against the design brief • evaluate your storage system and suggest further improvements.

Lesson 5: How will Joe Nixon collect evidence?
Learning objectives
By the end of this lesson you will be able to: • make and record observations at a crime scene • decide which observations might be used as evidence • collect evidence carefully and record it accurately.
Olympic Welcome pack
This pack has been distributed to • All athletes • All employees and volunteers • Corporate sponsors • The press
Contents • White recycled cotton ‘I used to be trousers’ T shirt • ‘I used to be car tyre’ recycled notepad • Pen • Map showing the location of all the main Olympic venues
Collecting evidence at the crime scene
You are now going to collect evidence from the crime scene. 1. Hair and Fibres 2. Blood samples 3. Ink samples 4. Fingerprints
5. Shoe prints
What other evidence is there?
At each station collect any additional information.
You should:
• take photographs • draw pictures • collect background information • add all this information to the evidence collection file.

Whodunnit?
• Add all additional information to the evidence collection file. • Use the booklets to decide on the strongest evidence. • Can you eliminate any suspects? • Can you prove any one guilty?
Collecting evidence
In this lesson you should collect evidence and complete these sheets in your Evidence Collection File: • • • • 4 6 7 8 Evidence Collection Sheet Make a sketch of the crime scene Identifying the Prime Suspect Summarising the Evidence
Lesson 6: How will Jo Nixon analyse evidence?
Learning objectives
By the end of this lesson you will be able to: • analyse evidence using some scientific techniques
• put evidence in order according to its strength
• propose a hypothesis based on different types of evidence.

Lab report on clothing and hair
Analysis of the hair sample shows that it is: • dark brown • not dyed • naturally straight • had been cut and not shed from the head Analysis of the clothing fibres shows that they are an exact match to the material used to create the T-shirts in the Olympic welcome packs. Use this evidence, along with the chromatography results to • rule out any suspects you can • write up your report for the tests that have been carried out so far. Remember that the report is going to be used in court, so don't just guess. Anything that you put in it has to be justified scientifically.
How will Jo Nixon analyse the evidence?
Fill in the Evidence Collection File • Share ideas of your findings • Collate and rank the evidence
Lesson 7: How can CCTV help find the thief?
Learning objectives
By the end of this lesson you will be able to: • select data to make good estimates of distance • use coordinates to locate key positions on a scale map
• analyse numerical data and use it to eliminate suspects from the investigation.

The Olympic Park
How can CCTV help find the thief?
In pairs: • List the different modes of movement that people use to move around the Olympic Village walking, cycling, etc. • For each mode of movement estimate an average speed over 2 minutes.
• Decide which type of running (sprint, middle, long) would be most appropriate to the size of the village.

• use evidence to support a conclusion
• suggest criteria for assessing a presentation
• plan a presentation according to pre-set criteria.
Making the case for prosecution
• Recap the enquiry so far. • Decide who the culprit is. • Prepare a group presentation with reference to the criteria. • One set will test the strength of the evidence.
• One set will test the quality of the presentation.
Lesson 9: Crown Prosecution Service Case conference
By the end of this lesson you will be able to: • present an opinion based on evidence from a variety of sources • use appropriate media to convey ideas and information effectively • construct a presentation to meet agreed criteria
• use the criteria to assess the work of other groups.

• • • • • • • Make sure you can be heard Get people interested Leave time for questions Consider your appearance Avoid reading text Keep your hands free Consider using some audio visual material
Assessment Criteria
How well did the group explain:
• The significance of each type of evidence?
• The logic in incriminating or eliminating suspects?
• How well did the pupils work as team?
• Did the group stick to schedule? • Other agreed criteria
