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 new curriculum series by the Smithsonian Science Education Center. It is aligned to a group of grade 2 standards. It has a focus on physical science with a secondary focus on engineering. In this module, students:

  • Organize solids by color, shape, and hardness
  • Obtain information from a text about how hard and soft materials are used to make different types of sculpture
  • Carry out investigations to see whether a sculpture made from pieces can be taken apart and made into a different sculpture
  • Argue from evidence for whether sand is a solid or a liquid
  • Analyze data from tests to find the best material to use in a cold pack
  • Construct an explanation for how a silver necklace can be made starting from wax wrapped in clay
  • Plan and carry out investigations to find the best material for a replica gemstone
