Challenge Brief

The Problem Disaster has struck Hampshire. A powerful geomagnetic storm caused by a solar mass ejection (or sun storm) has caused all the electrical systems in towns throughout the county to crash. Power is out, water has stopped flowing, hospitals and schools cannot operate and transport and food distribution infrastructures have collapsed.

The Challenge You’re the engineer rescue team tasked with getting the town up and running Watch the briefing video and make your way through the online challenge to Save the Day!

Help? Teamwork – you will need to work in teams just like real engineers ? button has hints, tips and formulas to help you find solutions

Online Challenge You have about an hour to: Create your team Watch the video briefing Start Power to the People Challenge Make a start on the 4 mini challenges and 4 code cracker challenges Short break

Are you ready?

Tools down! 10 minute break

Online Challenge You have just over an hour to: Finish all the mini challenges and code crackers

1)Radio Communications 2)Traffic Control 3)Hospital 4)Water Works Well done you’ve accessed the mainframe! Now, select the challenges in this order…

The X-axis is the one along the bottom The Y-axis is the one up the side Part 1: Radio Communications

What do you need to do to 7 to make it 10? What do you need to do to 3 to make it 1? Part 2: Radio Communications TIP: Is it plus or minus?

1.Fill in the flow chart with what you think works 2.Imagine the scene of the traffic lights 3.Go through the flow chart you have created 4.Does it give enough time for your cars to go through the lights Part 1: Traffic Control TIP: Click on the traffic lights to see the sequence the lights turn

1.Fill in the flow chart with what you think works 2.Try and imagine the scene of the boat, bridge and car- go through the flow chart you have created 3.Does your imaginary boat and cars make it under and over the bridge safely? Part 2: Traffic Control If not, change it and try again

A flat straight line means the object isn’t moving A curved line means the object is getting faster (accelerating) or slowing down (decelerating) A sloped straight line means the object is traveling at the same speed and the steeper the line, the faster it’s going Part 1: Hospital This is a DISTANCE TIME graph. And here’s what you need to know about these:

Distance must be in kilometres not metres Time must be in hours not seconds (divide by 60) Answer must be to nearest whole number BUT… Part 2: Hospital

TIME = DISTANCE divided by SPEED You need the answer in MINUTES not hours BUT… TIP… You know what ½ hour is in minutes, right? Yes, 30! What did you do to get from ½ (or 0.5) to 30? Part 3: Hospital

1. Work out the GEAR RATIO INPUT SPEED (rpm on left) divided by OUTPUT SPEED (rpm on right) GEAR RATIO 2. You then know that… TEETH ON DRIVEN GEAR = = TEETH OF DRIVER GEAR times by GEAR RATIO Part 1: Waterworks

1. Again, work out the GEAR RATIO = OUTPUT SPEED (rpm on right) INPUT SPEED (rpm on left) GEAR RATIO [divided by] Part 2: Waterworks

2.What is the gear ratio as a fraction? Fill it in below. Then click the forward arrow for help… = TEETH ON DRIVER GEAR TEETH ON DRIVEN GEAR Top part of Gear Ratio Fraction is... Bottom part of Gear Ratio Fraction is … many times larger than this. will be thisThis
