Week of Dec. 7-11

December 10:

Math: Your work on adding and subtracting fractions was amazing! Don't forget that if you simply have proper fractions to write the number sentence horizontally, and when adding or subtracting mixed numbers, write the number sentence vertically. Keep up the great work!

Science: We looked at solids, liquids, and gases today.

Solids have a definite volume and a definite shape.

Liquids have a definite volume but no definite shape.

Gases have no definite volume or definite shape.

Math: We continued adding and subtracting fractions today. Remember that when we add or subtract mixed numbers to add or subtract the fractions first before the whole numbers. Don't forget to convert any improper fractions to mixed numbers as well.

Science: Another physical property of matter is the ability to sink or float. We saw that the larger foam ball actually sank when compared to the smaller golf ball. Just because an object is large doesn't necessarily mean that it will sink, and just because an object is small doesn't necessarily mean that it will float. The clay activity is always fun, and it was so cool to see your minds at work in figuring out how to make it float! Check out the photos!

December 8:

Math: The last section of fractions includes rounding to nearest 1/2 and adding and subtracting fractions. Fractions that are one part away from the half will round to the half; most unit fractions will round to zero; fractions that are one part away from one whole will round to 1.

Science: Magnetism is the pushing or pulling force between the poles of magnets. Opposite poles (N & S) will attract; like poles (N & N, S & S) will repel. Only certain metals (iron, nickel, cobalt, etc.) are attracted to magnets.

December 7:

Math: We began working on a comparing fractions practice. When comparing fractions, show an EFT for both. As soon as you find a common numerator OR denominator, stop, and compare the two. Don't forget to show the comparison of the original fractions and then flip them in case you don't see the exact answer in the answer choices.

Science: Displacement is finding the volume of an irregularly shaped object (toy car, pencil, ball, rock, etc.). Matter is anything that has mass and takes up space, therefore, the golf ball took up space in the water when it was dropped in the graduated cylinder. The water level started at 200 mL before the ball was put in, and the water level rose to 240 mL after it was dropped in. 240 mL (water and ball) - 200 mL (water) = 40 ml (volume of ball).
