Equipped with a magnifying glass and three different samples of sand, second graders took on the roles of scientists. As part of a hands-on activity in Eileen Scanlon’s class, they made observations about the color, size and shape of each sand sample.
Scanlon said the students asked questions about how the sand came to be the way it is and wondered how it was formed. Throughout their Amplify Science unit on landforms, they have been learning that landforms change over time.
“Since they can’t observe that change directly, the students made sand observations to determine what landforms are made of and eventually come up with ideas about why and how landforms change,” Scanlon said.
