How Can We Change Solids And Liquids?

How Can We Change Solids And Liquids?

How Can We Change Solids and Liquids? is part of Smithsonian Science for the Classroom, a curriculum series by the Smithsonian Science Education Center. It is designed to address a bundle of grade 2 engineering and physical science standards. In this module, students:

  • Construct an explanation for how an artist made a sculpture from marine debris.
  • Use observations to describe patterns of behavior in solids and liquids.
  • Construct an explanation about what happens to crayon wax when heated and cooled.
  • Design a solution for changing melted crayons into crayons they can use.
  • Compare a variety of materials to make a prediction about which ones will make the best filling for a boo-boo pack.
  • Analyze data from tests of their selected boo-boo pack materials to determine if they work as intended after being frozen.

Below are digital resources that support teaching of this module.

Washed Ashore Image Gallery
Use this gallery of the huge variety of artworks created as part of the Washed Ashore project to engage and inspire your students. As an enrichment activity, encourage students to think about how they could repurpose plastic items to create a piece of art that would raise awareness about the problem of plastic pollution in our oceans.

Tami’s Tower
In this game, used in an extension activity, students have to build a tower to help Tami, the golden lion tamarin, reach the fruit. Tami’s Tower is available online and as a mobile app. It is also available in Spanish.
