TimeTitle, Description, Teacher Notes
Introduction Common views of maths: It's dull and boring BUT this is not the case. This lecture will explain how maths can be used to fight crime better than any superhero in town.
Challenges A who dunnit investigation begins. What are the challenges facing police?
Inverse problems Using probability and statistics. How can maths be used to de-blur fingerprinting. Using this as a starter for a lesson on probability or statistics would get KS3 or KS4 students enthused about these subjects.
Examples of inverse problems This shows how the shadow of an aeroplane can be used to theorise the shape and size of the actual model. It highlights cause and effect of problems and uses formula for calculations. Remote sensing solutions for inverse problems such as the length of time a body has been dead.
Case study one Uses of mechanics to help solve crime. What happens if you find a bullet embedded and how can you determine where the bullet came from? How can you tell if a car has been speeding by the skid marks? Again this can be used in either KS3 or KS4 as a starter and to get the students interested in the topic.
Case study two What poisoned the water? Uses maths to calculate flow rates and catch the perpetrator.
Case study three De-blurring a number plate! Description; How maths can decipher a number plate even if it only partially seen. This is an excellent example to show students although the formula used is complicated.
Case study four Who killed tutankamon? Uses maths to solve a crime that happened over 3,300 years ago! I won't spoil this for you, watch for yourself. It is definitely worth watching.
Case study five How maths can be used to find anti-personnel mines. This is extremely interesting and will allow students to see many different applications of maths. This will encourage students to follow professions in maths in three minutes!
