This week students reviewed percent change (increase and decrease). They also practiced simple and compound annual interest. Students compared simple and compound interest.

This introductory week in Fitness was sure to bring on sore muscles. Students were introduced to a variety of exercises, while focusing on correct technique to minimize injury. The exercises were put together in a series of workouts. We will continue having fitness during the next two weeks of health.
Tips on a full air squat: feet outside hips and inside shoulders, toes pointed forward (or slightly turned out...whatever your hips allow you to do), heels flat, chest up, squat down until your hamstrings cover your calves while keeping your knees out tracking over your feet. At no point should your knees be in front of your toes. If you keep falling backwards during your squat or your heels come up, find a spot where your heels can be higher than your toes and try it. You will find that once you start to open up your hips and stretch out your calves, a squat will become easier.
In health, we began to read the book, "Chew On This." This book is a 'tell all' book based on the implications of fast food from both a health and an ethical standpoint.

Community Event: Sunday, January 10th. Join me and Golden Eagle Audubon Society members for a family bird walk in Marianne WIlliams Park from 1 - 3 pm. Binoculars and guide books will be provided. Meet in the parking lot near the ponds.
Words Worth Knowing: wind chill, upwelling, thermocline, anemometer
Students presented their weather forecasts this week. Based on their presentation skills, I think that there might be some future news and weather casters in this groups of seventh graders. Following their presentations, students were able to view the actual data from the weekend and reflect on their accuracy. On Wednesday, the students explored how La Niña and El Niño global weather patterns. Currently we are experiencing an El Niño that is tied for the strongest in recorded history. Finally, on Thursday students learned about causes and impacts of temperature inversions. Next week students will be independently researching either an extreme weather event or a category of events (example Hurricane Katrina or hurricanes). Students, you may want to have your own device available to use for researching next week. This assessment will be due next Thursday. All reassessments and late work need to be submitted by Thursday, January 14th in order to prepare for the end of the semester. Click the links below to learn more about topics covered this week.
