Temperature+and+Measurement

= Hello Class 5/6J. = = Welcome to the Measurement and Temperature page. = = = = Why do we measure? = =Why do you think we need to use formal scales of measurment such as metres (m), for measuring the length or height of something, square metres or hectares for measuring the area of something, and degrees celsius for measuring how hot or cold something is? Is it important to know how hot or cold something is in accurate degrees? = = = = Why do we need accurate formal systems of measurement that are the same across many countries rather than informal measurments such as "about a foot long" or I will buy "10 yards of that material please"? In Australia, as in many other countries around the world, we use the metric system of measurement. This means we talk about the length of something as being 10 metres long, or the height of a building as being 7 metres high, or the area of a football field being about 500 square metres. (//Can somebody find out for me what the area is of a football oval because 500m2 is just a wild guess, not even an educated guess?)// = = = = Some old terms we used to use for measurement include a 'hand', a 'curbit', a 'foot', and a 'furlong'. Do you know where these terms originated from? Is everyone's foot the same? Is everyone's 'yard' the same? = = = = Talking about Temperature = = = = What are some informal terms for talking about how hot or cold something is? Does your term mean the same as mine? If it is hot enough "to fry an egg on the road" how hot do you think that would be in degrees? If it is cold enough for the windscreen of your car to be covered in ice in the morning how cold does it have to be in degrees? = = =

LAVA: Molten Lava coming straight out of a volcano can be as hot as how many degrees?

ACTIVITY: Collecting Measurements of Temperature
== Record the measurements you collect from your strategically placed thermometers (somewhere in the playground) in the tables below. We have three thermometers we will use to measure readings at certain times of the day, or over a week. We will have three groups; each group can decide where they wish to locate their thermometer. Each group can record their temperature readings in a table below. Once there is enough data we will make a graph out of this data in your workbooks to visually present the data you have collected. ==

LOCATION ONE:

Activity: The Sahara Desert
== Write a Narrative about what you think the temperature would be like in the Sahara Desert, and how you think you might feel walking around in the desert. (You may wish to do some research on the Sahara Desert). == = = = Activity: Thermometers =

Write an Information Report on how we use thermometers to measure the heat of something. You will need to talk about the Celsius Scale.
