Heredity is the passing of genetic traits from parent to offspring. This is done through dominant and recessive genes.

Dominant genes are the strongest and are usually labeled with a capital letter - "B" for brown, for instance.

Recessive genes are typically hidden by dominant genes. Label the recessive gene for blue eyes "b" - lowercase.

If you get two dominant genes for eye color - BB - you're a brown-eyed beauty. Inherit a dominant and a recessive gene - Bb - you get the dominant color: brown. When both parents contribute a recessive gene, in this case blue-blue or bb, you've got blue eyes. These examples are all inherited traits.

Inherited traits are characteristics that are determined by an organism’s genetics and passed from parent to offspring. This can include eye color, hair color, skin type, height, etc.

Acquired traits, or learned behaviors, are behaviors that are acquired by an organism’s interactions with its environment and /or parents. This can include riding a bike, swimming, drawing, climbing, etc.

Inherited behaviors are behaviors that are instinctive. This includes breathing, smiling, blinking, etc.

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...
