Tell your child that tall buildings sway slightly in the wind. This is one of the many factors architects and engineers consider when designing a building. Share the formula that determines how much a skyscraper will sway to the left or to the right: building height (H) divided by 500 = sway amount (X). H ÷ 500 =X
Use the formula to calculate how much these buildings will sway:
Two International Finance Centre: 1,362 feet tall. (1,362÷ 500 =2.72 feet)
Have your child put the buildings above in order, by height; then graph from tallest to shortest.
(1. Burj Khalifa; 2. Taipei 101; 3. Shanghai World Financial Center; 4.&5. Petronas Towers 1&2; 6. Willis Tower; 7. Trump International Hotel & Tower; 8. Jin Mao Building; 9. Two International Finance Centre; 10. CITIC Plaza)
Metric Conversion Convert heights to metric equivalent for the top three buildings. Create an equation using this information: one foot = 0.3048 meters. (Height in feet [F] x 0.3048 = height in meters [M])
Burj Khalifa: 828 Meters tall (2,717 x .3048 = 828)
Taipei 101: 508 Meters tall (1,667 x .3048 = 508)
Shanghai World Financial Center: 492 Meters tall (1,614 x .3048 = 492)
This month Katherine Paterson begins her reign as the new National Ambassador for Young People's Literature. Paterson authored Newbery Medal-winning books Bridge to Terabithia (1977) and Jacob Have I Loved (1981), among others. During her two years as ambassador, Paterson will work to remind and inspire parents and kids of the joys and importance of young people's literature.
At the end of December, the Bureau of Land Management began a two-month roundup of wild horses in northern Nevada. The aim is to remove about 2,500 mustangs from public and private lands. Federal officials say the move will protect the habitat of a variety of wildlife—wild horses included. The horses will receive veterinary care upon capture and will eventually be put up for adoption.
Activity Ideas Math Tell your child that more than 3,040 wild horses were living in northern Nevada as of September.
If 3,040 is three times what the land can support, how many horses can the land support? (1,013 horses)
Without the roundup, the population could grow by 20-27% a year. Assuming it grows by 20%, how many horses would there be after one year? (3,648) // Two years? (4,378) // Three years? (5,254) Four years? (6,305) Five years? (7,566)
Now, imagine the population grows by 25%. Calculate the resulting population numbers by year. One year: (3,800) // Two: (4,750) // Three: (5,938) // Four: (7,422) // Five: (9,279)
About half of the nearly 37,000 wild mustangs live in Nevada. Estimate how many live in Nevada. (18,000) Now, calculate the number: (18,500)
