In Ana Belen Garcia's third-grade science classes we did a very interesting project.
The students completed a chart during one week, and recorded their habits. The categories included physical activity, screen time (watching TV, playing computer games, or playing nintendo), and sleep time.
We learned that it's important to have a balanced life, by eating healthy, having friends, doing physical activity, and resting. Some students reported using the blog to play games and learn, which is also excellent!
