Today is Monday. But Dale and his classmates don’t have     2     in the classroom—they are on a trip to the science museum. They want to     3     some things about science.

In the museum, they see many     4     things. Dale likes the Color Room on the     5     floor (楼层) in the museum. In the room, the students learn about seven colors of the rainbow. They learn how to make a rainbow with a mirror (镜子) and water, too. It is fun and useful for     6    .
