THERM

THERM THERM means HEAT Therm is the second root featured on the Resource Room found often in scientific contexts. I. FOR EACH WORD: 1. Write the word 2. Write what it means 3. Draw a picture to go with it 4. Answer the question about it. word meaning and example what to draw question to answer (you may draw your answer, too) thermometer thing to measure temperature (amount of heat) Two different kinds of thermometers What do you think the "meter" part of "thermometer" might mean? thermal having to do with heat or conserving heat ('thermal blanket,' 'thermal underwear') a "thermal" object Why is 'thermal underwear' called that? thermostat machine that keeps something at the same temperature (or 'heat level'); "stat" means 'same.' a thermostat (there may be one on the wall where you are). What would you have to do if you didn't have a thermostat? geothermal heat coming from the earth (remember from the 'logy' group that geo means earth); volcanoes and hot springs are examples of geothermal heat sources. a source of geothermal energy Where are two places where geothermal energy can be found? hypothermia when the body's temperature goes below normal someone with hypothermia What are two ways a person could develop hypothermia? What do you think "hypo" means? hyperthermia when the body gets too hot (such as during heat stroke or a high fever) someone with hyperthermia What are two ways a person could develop hyperthermia? What do you think "hyper" means? thermonuclear change in an atom's nucleus that requires a very high temperature, such as in a hydrogen bomb or in the sun a place where thermonuclear action is happening What would happen if a thermonuclear bomb went off? Thermos a container designed to keep heat in or out to keep food at a desired temperature a Thermos What are three different foods that would likely be kept in a Thermos? isothermal a line on a map showing where the temperature is the same along that line an isotherm (you might want to look in an encyclopedia) What kind of job (-ologist) would be interested in isotherms? (See "-logy" words) endothermic taking heat into itself (making it get colder because it's taking heat away) Draw two test tubes with thermometers in them - one before, one after an endothermic reaction Why is the second test tube colder than the first one? exothermic sending heat out (getting hot to the touch) - much more familiar than endothermic reactions - and getting warmer. Draw two test tubes with thermometers in them -- one before, one after an exothermic reaction Why is the second test tube warmer than the first one Complete these sentences with the "therm" word that fits. Be sure to mix these sentences with words learned in previous lessons. 1. Getting wet on a cool day and staying out side can lead to hypothermia 2. You can get a thermometer that will measure temperature in Fahrenheit or Celsius. 3. I have a Thermos full of coffee, piping hot. 4. A thermal blanket is designed to add a warm layer for cold weather, but not be too warm in warm weather. 5.The isothermal showed that it was 32 degrees in Boston, Massachusetts and 30 miles north of Cleveland, Ohio. 6.A thermonuclear bomb does more damage than other kinds of bombs, but is very expensive to make. 7. Spending too much time in the hot sun can cause hyperthermia, which can be fatal. 8. That endothermic reaction got very, very cold. 9. Setting off a thermonuclear bomb is an example of an exothermic reaction because it sends out a lot of heat. 10. In Greenland, geothermal energy from hot springs is used to heat houses. 11. A tree farmer might want to study dendrology 12. That's an interesting rock! A geologist could tell you what it is. 13. The thermostat in my car broke, so it overheated.
