The Changing Moon

How the moon's appearance changes

during the lunar cycle?

EngagementOne summer Woody and Lynn's

mom and dad sent them to summer camp. Every night they went looking for snipes. On the

first night they noticed the moon was very large and bright. As

each night passed, they noticed that they could see less and less of the moon. Woody said it was because the sun is in a different

position each night. Lynn disagreed. She said "You're

wrong! It' the position of the moon that changes."
