TT 1. Work with a partner if possible. Use the multimedia tool or a real thermometer to record the temperatures in Celsius and Fahrenheit for these three different situations. Discuss and record your observations.

Situation	Temperature on the Celsius (°C) Scale	Temperature on the Fahrenheit (°F) Scale	Observations About the Two Temperature Scale Readings
Freezing/Melting Point of Water cup of water full of ice (Record the temperature when half the ice is melted.)
Ice/Salt Mixture crushed ice with a handful of salt (Record the temperature once the ice has started to melt.)
Body Temperature armpit (Record the temperature after three minutes.)			n/a

It’s time to share your answers to TT 1. Remember that sharing work is an important part of learning. Use the following tips to ensure you get all the benefits from this sharing opportunity:

Complete the questions to the best of your ability. Make sure your answers are in a form that you can easily share with another student or with your teacher, if so directed.
Use your class discussion area, or another method indicated by your teacher, to post your answers and to view the work of the people you’re sharing with.
Compare your answers to the other posted answers. Identify where you have similar answers and where your answers are different. Discuss all differences between answers until you agree on the answers. If necessary, you may wish to involve your teacher in your discussion.
Revise your answers where necessary.

Save a revised copy of your work in your course folder. Ask your teacher whether you should also save a summary of your discussion in your course folder.
