My Science Teacher① Usually when people decide to be teachers, they go to college, get a degree, and find a job at a school. They prepare lesson plans, give out homework, and make up tests. To them, it is just a job, a way to make a living. But for my science teacher, Mrs. Cook, teaching is not just her job; it's who she is. She teaches through her heart.② She has so much enthusiasm in her lessons. She is the one who goes out late at night to buy 10 pounds of sugar for our experiments She brings in water from the nearby canal to make her point, and to make us remember the lesson. She makes us think that each new fact could change our lives.③ Mrs. Cook wants all of us to do well in school. She tries to reach each student. She neither ignores the sleeping kid in the back nor lets the problem students alone. She shows special concern to slow students, and often helps them after school. None of us can slip away from her attention.④ Middle school is probably one of the hardest times of our lives. We change friends so often, and fight with our parents constantly. But Mrs. Cook has made this year so much better for us than it could have been. We know that if we had to turn to anybody, it would be her. And I'm not alone in feeling this way; she is a role model for our whole class.⑤ Science had never been my favorite subject. I had never borrowed science books. had never performed experiments in my home. But this year, it's the science class that I don't mind waking up for, the test I don't mind taking.
