Introduction
You are a participant in the challenge of travelling with “Heat & Temperature Technologies.” In order to win, you must successfully travel from Innisfail to Toronto. There will be some challenges along the way for you to complete before you reach your final destination.
Task
Eight challenges must be mastered in order for you to complete your journey.
Process
Open The Amazing Race Web Quest Worksheet to record your answers to all eight challenges.
Challenge 1: You are travelling from Innisfail to Moose Jaw by “Greyhound Bus.” It is 25 degrees Celsius in the morning and it is supposed to reach a high of 38 degrees Celsius by early afternoon. Around 3:00 pm the bus driver starts to sway back and forth on the highway until finally he screeches to the side of a road. He notices he has a flat tire, however, there is no debris found in or around the tire. Using the particle theory, explain what might have happened!
Challenge 2: Since the bus will take a few hours to repair you are desperately looking for a quicker ride. Out in a farmers field is a young gentleman just about to get into a HOT AIR BALLOON. You ask him for a ride to Moose Jaw.
Before you can get in you need to explain how convection works in case you are needed to pilot the balloon.

Challenge 3: The hot air balloon stops in Moose Jaw. You thank the gentleman and go on your way. About 30 minutes later you take a break to take a drink of hot chocolate from your thermos. You start to wonder how a thermos works. Explain in a paragraph, in your own words, how a thermos uses conduction, convection and radiation to keep your hot chocolate hot.

Challenge 4: After you have warmed up from your hot chocolate you are wondering what the temperature outside is. The problem is you do not have a thermometer with you. Use the following site to explain how to make your own thermometer.

Challenge 5: After you have found out the temperature outside you decide to keep walking down the highway where you eventually get picked up by a man going to Winnipeg. Just outside of Winnipeg you come across a huge brush fire. You get out of the car and feel the heat from the fire and start moving away. Explain in two or three sentences how a fire demonstrates all three forms of heat transfer.
Challenge 6: What is the formula to convert degrees Fahrenheit into degrees Celsius and celius to Fahrenheit.

Challenge 7: After helping the fire department put out the grass fire you decide to hop a train going East. After a long journey it comes to a sudden stop due to a break in the track. You have arrived in Toronto where the temperature is around –11 degrees Celsius. The foreman is unsure of how far to space the rail apart in order to compensate for the expansion and contraction of the rail. Use the information and the chart from the website provided to find the correct distance the foreman needs to space the rail. (be careful, the chart states temperature in degrees Fahrenheit) Show all work.
