Compare and Contrast

This week in LA, students have been working on compare/contrast brochures. Students chose a topic to explore and wrote about the topic's similarities and differences. These brochures are due on Wednesday whereupon the students will share their brochures with the class.

Week of March 5

Have you ever wondered why Leap Year exists? Here is some interesting information about it.

Leap Years are needed to keep our calendar in alignment with the Earth's revolutions around the sun. It takes the Earth approximately 365.242199 days – or 365 days, 5 hours, 48 minutes, and 46 seconds (a tropical year) – to circle once around the Sun.

However, the Gregorian calendar has only 365 days in a year, so if we didn't add a day on February 29 nearly every 4 years, we would lose almost six hours off our calendar every year. After only 100 years, our calendar would be off by approximately 24 days!
