1. KS2 project introduction SaRKS2project.lgfl.net

2. Search and Rescue – sar.lgfl.net© 2016 London Grid for Learningsar.lgfl.net Introduction Throughout this project, pupils will take on the role of the Coastguard and search and rescue teams. They will discover how to practically apply Maths in a real world context. This first session is an introduction to the types of situations they might be involved in.

3. Search and Rescue – sar.lgfl.net© 2016 London Grid for Learningsar.lgfl.net Teacher guidance notes In this session, students will watch a short video then respond to some stimulus questions. These questions will help prepare them for the Maths they will be doing in the main project, and will help teachers identify potential teaching points and misconceptions. There will not necessarily always be a ‘right’ answer, but please encourage students to reason mathematically. This session should take 1 hour. Each project will take between 1 and 2 hours to complete, but could be extended to encourage students quality of mathematical communication.

5. Search and Rescue – sar.lgfl.net© 2016 London Grid for Learningsar.lgfl.net 1. Rescuing a large crew Watch this video: Introduction to the SaR helicopterIntroduction to the SaR helicopter 1.How long would it take the helicopter to travel 50 miles if it was travelling at 100mph? 2.With 3 hours of fuel travelling at 150mph - could the helicopter support a rescue 200 miles away and get back to the base? What assumptions have you made?

6. Search and Rescue – sar.lgfl.net© 2016 London Grid for Learningsar.lgfl.net 2. Helicopter technical specifications Watch this video: Helicopter rescue - angled rescueHelicopter rescue - angled rescue 1.How long do you think it would take to winch out 4 people at a time? 2.If the boat was 20 miles from the helicopter base, how long do you think it would take the helicopter to travel between the boat and base? 3.Using your estimates to part 1 and 2, estimate how long a complete rescue would take (25 people).

7. Search and Rescue – sar.lgfl.net© 2016 London Grid for Learningsar.lgfl.net 3. Fuel calculations Watch this video: SaR helicopter – Part 2SaR helicopter – Part 2 1.The pilot says that 1000 kg of fuel would keep the helicopter airborne for 2.5 hours. How much fuel would they need for 1 hour? 2.How long could they stay airborne with 600 kg of fuel? 3.How long could they stay airborne with 900 kg of fuel?

8. Search and Rescue – sar.lgfl.net© 2016 London Grid for Learningsar.lgfl.net 4. Search and rescue technology Watch this video: What tech is used to spot casualties?What tech is used to spot casualties? 1.If you have 100 lumens over 4 square metres, what will the lux be? 2.An area of 4000 m2 is lit to 80 lux by the search light. How many lumens are cast across the area? 1 lux = 1 lumen / 1 metre 2 This means that 1 lux casts a light with the power of 1 lumen on a metre 2 (equivalent to 1 candle).

9. Search and Rescue – sar.lgfl.net© 2016 London Grid for Learningsar.lgfl.net 5. Controlling a helicopter Watch this video: How do you control a helicopter?How do you control a helicopter? Write a description of how you would fly the helicopter to the boat using angles and height. EXT: Include which levers/pedals you are using and any angles/timings that might be relevant.

10. Search and Rescue – sar.lgfl.net© 2016 London Grid for Learningsar.lgfl.net 6. Helicopter winch operator En route to a rescue scene you are told that there are 56 people on board. 20 are injured. 19 are children (10 of which are injured) and 15 are women. 16 men are not injured. 1.Create a two-way table to help make sense of the situation. 2.Decide on a rescue strategy, prioritising who to rescue first. Give reasons for your choices.

14. Search and Rescue – sar.lgfl.net© 2016 London Grid for Learningsar.lgfl.net Creating a rescue plan Coastguards need to work out the following when creating their plans: Time taken to get to site for boats/helicopters Time taken to rescue people from the vessel The range/endurance of the helicopters/boats (will they need to refuel?) Is anyone overboard? If so, they need to act quickly to help them to prevent hypothermia.
