This Wikispace has a large list of links that are useful for all subject areas. I hope this information helps you in you classroom. I am always thrilled when I come across resources that I can use in my classroom!
One link I have explored from here is www.healthehuman.com.
This website is an online daily health tracker. The tracker has 20 different features for logging your daily health, from medicine tracking to sleep tracking and diet and exercise to body measurements. The website (http://www.healthehuman.com/features/trackers) states that "each tracker is designed to help you quickly input, organize and understand that specific area of your health through an intuitive interface, insightful daily summaries, charting and analysis features, a flexible goal management feature, and an extensive set of reporting and data export features."
How I can use this in my classroom:
I would use this website during a Fitness Testing unit. During this unit, students learn the importance of physical fitness and about Body Mass Index (BMI). Students can use this website to set health goals for themselves and be able to manage their progress, which is significant due to the importance of students keeping track of their health habits, which is precisely what this tool offers.
