In this salinity worksheet, students simulate conditions of salt and fresh water mixing and observe the various densities of these solutions based on their salinity.

Students observe 2 demonstrations of density. In this density lesson plan, students observe a vial with various substances of different densities. Students then observe the differences between a diet coke and a regular coke can when on a...

In this density demonstration, students compare a can of diet coke to a can of regular coke. They list the similarities and differences of each prior to the demonstration. The cans are placed in a tank of water and students record their...

In this forces in fluids worksheet, students identify the principles behind the forces acting upon objects in fluids that make them float, lift and spray.

In this plastics worksheet, students experiment with an unknown plastic and determine the polymer name and resin code by using a flow chart of various tests. They answer five questions after they collect their data.

Students participate in a hands on activity simulating an oil spill. In this oil spill lesson plan, students conduct an experiment about an oil spill, discuss how it would affect the environment and provide solutions to prevent oil spills.

Students investigate surface tension in water. In this water molecules and surface tension lesson, students observe 3 demonstrations to show how water molecules are attracted to one another, how soap reduces the surface tension in water...

Students examine geographical change. In this mountain barriers lesson, students conduct an experiment to discover how mountains affect surrounding land.  Students draw conclusions on how change in land affects plant and animal life.

Students use streaming videos, web sites, and hands on activities students to explore matter. They focus on how temperature affects matter and what the particles look like in the states of matter.

Students experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine currents.
