Advice
Really getting involved with the students and their projects makes an impact on the kids. They look up to you! Being passionate about science, or even teaching, helps immensely during this experience, and makes the experience better for both you and the students! The days are long and the week seems to drag on, but you come home every day feeling so good about the impact you're making on the students each day, not to mention you're gaining experience with kids that can help you in the future (whether with your career or personal life).
