Greg¡¦s father bought Greg a microscope because he wanted to see tiny think .He used the microscope to observe many thinks. First, he saw salt through the microscope. The salt looks like big blocks, and the salt looks 100 times bigger than it really is. Then he looked at different thinks through the microscope and he found many interesting facts. From this story, we can learn how to observe think through the microscope. We also know every part of the microscope. From Greg¡¦s observation, we can understand ¡§Every little crystal of sugar and salt has sharp corners just like diamonds.¡¨ And that¡¨ The cotton thread was really many threads twisted together. We should be like Greg and observe things a lot. We can learn many interesting facts, and learn how to use the microscope. ~
