Thermometer Clip Art

ETC Thermometer Clip Art –“over 790 views of thermometers. The images include Fahrenheit, Celsius, single and dual, laboratory, and outdoor thermometers with readings to the nearest degree. Also featured is a collection of blank and antique thermometers found in various nineteenth century books.”

Measurement: Length


Length is a measure how long something is from end to end.

Forthcoming, in sha Allah when we study this in our unit……


Metric System

The centimeter, meter, and kilometer are metric units of length.
  • A centimeter is about the width of your thumbnail.
  • A meter is about the length of a baseball bat.
  • A kilometer is about the length of 10 football fields.

Homeschool Math Lesson on measuring Temperature


Do more than just practice reading thermometers. Skip the math textbook and try this lesson plan for a more enriching and real life interactive lesson on measurement of temperature. 
Across the curriculum connections in math, science, and language arts. Enhance it with Arabic (or other foreign language of your choice).
1. Introduce the concept of temperature and its measurement.


2. Explore thermometers
Terms to know (definition and spelling): thermometer, temperature; Thermo is a root that means “heat;” meter is a root that means “measuring device.”
Practice drilling student on terms and their spelling
3. Explore temperature measurement in the metric system
  • Learn the boiling and freezing points in this system (given in the video above)
  • Learn the range of room temperature in this system
  • Learn typical temperatures for a hot and cold day in this system
Terms to know (definition and spelling): Celsius
Make sure student can give these temperatures when asked; make flashcards and drill orally
imageActivity: Have student complete Temperature-Metric System Notebooking page with the following data:
  • Boiling point of water: 100 C
  • Freezing point of water 0 C
  • Room temperature* (Range 20-27 C) student should be able to define what this means
or make his/her own study page or poster.

4. Explore temperature measurement in the US Customary system
  • Learn the boiling and freezing points in this system
  • Learn the range of room temperature in this system
  • Learn typical temperatures for a hot and cold day in this system
Terms to know (definition and spelling): Fahrenheit
Make sure student can give these temperatures when asked
imageActivity: Have student complete Temperature-US System Notebooking page with the following data:
  • Boiling point of water: 212 F
  • Freezing point of water 32 F
  • Room Temperature* 68 to 77 F; student should be able to define what this means
or make his/her own study page or poster.
5. Explore changes in temperature
  • Given a before temperature and change, determine the temperature after the change
  • Given a before and after temperature, determine the change in temperature

Check out Enchanted Learning’s Temperature resources to support your Temperature study.
*Room temperature is a common term to denote a certain temperature to which humans are accustomed. Room temperature is thus often indicated by general human comfort, with the common range of 20 °C (68 °F) to 27 °C (80 °F), though people may become acclimatized to higher or lower temperatures.
The term can also refer to a temperature of food to be consumed, which is placed in such a room for a given time.

Measurement: Temperature


thermometer-dualTemperature: The degree of hotness or coldness of a body or environment.





Sample Mastery Goals for unit on metric measurement of temperature (elementary and up)
  • State the definition of temperature
  • Tell what instrument is used to measure temperature; what liquid is found inside and why that liquid is used and explain roughly how a thermometer works
  • Spell the following terms correctly: Celsius, temperature, and thermometer
  • Tell the boiling point of water
  • Tell the freezing point of water
  • Tell normal body temperature
  • Give an example of the temperature of a hot day
  • Give an example of the temperature of a cold day
  • Tell the range or a temperature of room temperature and what room temperature means

Temperature in the Metric System
Temperature in the Metric system is measured in degrees Celsius.
Celsius is a scale and unit of measurement for temperature. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale two years before his death.(Wikipedia)
BBC Temperature Interactive –  cute interactive where student clicks on a Celsius temperature and it shows a graphic illustrate the conditions of the environment at that temp. Tip: When you click on a temp, it displays the graphic for quite some time that you would think it was stuck; however it returns to the home graphic and you can select another temp.
Temperature in the US Customary System
Temperature in the Metric system is measured in degrees Fahrenheit.
Fahrenheit is the temperature scale proposed in 1724 by, and named after, the physicist Daniel Gabriel Fahrenheit (1686–1736). Today, the temperature scale has been replaced by the Celsius scale in most countries.[1] But it is still used in nations such as the United States, and Belize.[2]   Source: Wikipedia, 2010_
Temperature on the Kelvin Scale
The kelvin is a unit of measurement for temperature. It is one of the seven base units in the International System of Units (SI) and is assigned the unit symbol K. The Kelvin scale is an absolute, thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics. The reference point that defines the Kelvin scale is the triple point of water at 273.16K (0.01 degrees Celsius). The kelvin is defined as 1/273.16 of the difference between these two reference points.
The Kelvin scale is named after the Belfast-born physicist and engineer William Thomson, 1st Baron Kelvin (1824–1907), who wrote of the need for an "absolute thermometric scale". Unlike the degree Fahrenheit and degree Celsius, the kelvin is not referred to or typeset as a degree. The kelvin is the primary unit of measurement in the physical sciences, but is often used in conjunction with the degree Celsius, which has the same magnitude. 0kelvin is −273.15 degrees Celsius

  • Take a liquid thermometer and leave it sitting out on a table for a few minutes. The temperature it shows will be the same as the temperature in the room

  • Pour a glass of ice water, and stick the tip of the thermometer into the water. Watch the way the liquid quickly shrinks down as it picks up on this new change in temperature!

  • Now, stick the end of the thermometer into a glass of warm water, and watch what happens! The red liquid inside will quickly shoot back up, showing you that it's now detecting a warmer temperature! Cool!!

Finding the Least Common Denominator


When adding or subtracting fractions with different denominators, you’ll need to find a common denominator. It is better to find the least common denominator so that there will be less work when it comes time to reducing the final answer.
“The least common denominator of two or more non-zero denominators is actually the smallest whole number that is divisible by each of the denominators.” (Help with Fractions.com)
When teaching my kids, I couldn’t pinpoint how to find the least common denominator, but rather just a common denominator (and sometimes they’d be huge!) So I went searching for methods, and this is what I have found.

For Younger Students:
Least Common Denominator Lesson from Math is Fun.com
Finding the Least Common Denominator (method of listing multiples)

Methods

Basically the same method illustrated in Ray’s Math:

Finding the least common denominator – part of another lesson, scroll down after Google Ad. (similar method as above)
3 Methods for Finding Least Common Denominator
Take The Frustration Out Of Finding The Least Common Denominator ( Help with Fractions.com) – shows 2 methods for finding the least common denominator (very detailed)
From my daughter’s algebra book:

Example using the above method:

Tools
Least Common Multiple Tool – Nifty, plug in three numbers and get your least common multiple/denominator. Great for checking your manual work.
Games & Interactives
Least Common Multiple Interactive – simple, yet neat online activity where student must find the LCM/LCD of numbers. This might be a neat alternative to doing problems from your textbook. (Only a handful of problems, but most are application problems)
Least Common Multiple (LCM) Game – super old site, but nifty idea for making a card game.
