Seasons

The Earth's seasons are not caused by the differences in the distance from the Sun throughout the year. The seasons are the result of the tilt of the Earth's axis. This tilting is what gives us the four seasons of the year - spring, summer, autumn (fall) and winter. Since the axis is tilted, different parts of the globe are oriented towards the Sun at different times of the year.

Summer is warmer than winter (in each hemisphere) because the Sun's rays hit the Earth at a more direct angle during summer than during winter and also because the days are much longer than the nights during the summer. During the winter, the Sun's rays hit the Earth at an extreme angle, and the days are very short. These effects are due to the tilt of the Earth's axis.

Measuring Angles with Protractors

  Measuring Angles with Protractors We are finishing out our geometry unit by using protractors to determine the measurement of angles. We have really been having fun with protractors! Here is a website that will walk you through the steps if you need a refresher:  Steps to Use a Protractor Kiddos will also need to be able to determine the degree without having a ray line up with the zero line. To do this, you need to skip count from one ray to the other to see the rotation degree. You can also subtract the degrees of the rays from each other (165-40=125 degrees or 140-15=125 degrees). When you are subtracting the degrees you need to be sure to use both outside numbers on the protractor or both inside numbers on the protractor. The angle below would measure at about 125 degrees. They will also need to be able to draw an angle using a protractor. Finding the missing angle is also a concept we have worked on. Angle COA is a straight angle and therefore measures 180 degrees. We k...

Fractions & Decimals

Image
  Fraction and Decimal Connections We are working on the connections between fractions and decimals. Decimals and fractions represent the same thing: a number that is not exactly a whole number. To convert fractions to decimals, decimals need to have a 10 or 100 in the denominator. Then you just plug it into the correct place value.                         So,  Here are some games that will help practice this skill: Model Decimals and Fractions Matching Game Puppy Chase Please let me know if you have any questions.

Weather Instruments

Image
Weather Instruments There are many types of instruments used to measure and collect weather data. Some of the instruments we are learning about include thermometers, wind vanes, anemometer, barometer, rain gauge, and weather maps. A THERMOMETER measures the air temperature. Most thermometers are closed glass tubes containing liquids such as alcohol or mercury. When air around the tube heats the liquid, the liquid expands and moves up the tube. A scale then shows what the actual temperature is. A BAROMETER measures air pressure. It tells you whether or not the pressure is rising or falling. A rising barometer means sunny and dry conditions, while a falling barometer means stormy and wet conditions. A RAIN GAUGE measures the amount of rain that has fallen over a specific time period. A WIND VANE is an instrument that determines the direction from which the wind is blowing. A WIND SOCK is a conical textile tube, which resembles a giant sock, designed to indicate wind direction and relativ...
