Sometimes, solid + liquid = gas
Third graders experiment with common household liquids and solids. In this chemical reaction lesson, 3rd graders discuss phase changes and experiment to find other ways to create gases. They use water, vinegar, lemon juice, flour, baking...

Classifying Shells
Pupils observe and classify different types of shells. They compare and contrast an exhibit they created with one that already exists in a musuem. They discover the different characteristics of shells.

Chemical Changes
Eighth graders observe two types of interactions in a sealed plastic bag. One bag contains baking soda and water, and the other baking soda and vinegar. They determine what evidence indicates that a chemical change is occurring.

Water and Ice
Students investigate how water changes state. In this water activity, students observe, measure, and describe water as it changes state. This activity includes extensions which can be accessed via the provided web links.
Curated OER
Melt the Ice
Students examine and discuss how water changes from a liquid to a solid to a gas. They explore this concept by having an ice cube race, competing to see which group can change the solid water back into liquid water first.
Curated OER
Liquids in Bottles
Students investigate different liquids to develop their concept of a liquid. They work at a center to tip, swirl, shake, roll, and otherwise investigate seven liquids in small, clear plastic bottles: plain water, corn syrup, liquid...

Project Geode
Students predict the appearance of a geode's internal structure based on its mass and density. They form a hypothesis based on the data they collect. They also identify common minerals found in Illinois.
Curated OER
Water and Ice
Students study the liquid and solid states of water. In this water states lesson, students complete three experiments to study water as it cycles from a liquid state to a solid state and back. Students finish with a Venn Diagram...
