In this plate tectonics worksheet, learners answer questions about plate tectonics including topics such as the lithosphere, the asthenosphere, rising and sinking convection currents, continental drift and the types of boundaries.

In this density worksheet, students answer 12 questions about the density of substances. They read a diagram of a graduated cylinder and determine the volume, mass of water. They interpret a diagram with three liquids and indicated their...

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

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...

Learners use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

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.

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.

In this forces in fluids activity, 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 explore the Big Bang Theory and the Theory of Plate Tectonics. In this history of life lesson, students explain two ways the Theory of Plate Tectonics and the Big Bang are of direct benefits to humans.

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 formulate a hypothesis using critical thinking skills. They use an orange to examine the displacement of water as the orange sinks or floats.

Students study the ocean and its characteristics.  In this oceans lesson students complete a lab activity and are able to predict temperature of certain depths. 

High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...

Students end up learning the formula for density and calculate the densities of various materials, and predict if they sink or float.

In this density worksheet, students complete a science lab experiment to determine the density that an object will float or sink in water. Students fill in a chart with their data, answer 4 short answer questions and write 1 conclusion...

Sixth graders investigate the properties of water. In this life science lesson, 6th graders create a concept map of water. They share their work with the class.

Pupils examine why some objects float in water while others sink and the ability of something to float does not depend entirely on its weight. Archimedes' principle is introduced and buoyant force is discussed. Practice calculations and...

In this biology instructional activity, students use the website given to become familiar with the equipment of a lab. The activity involves a link to a virtual laboratory. Then they determine an objects mass and volume by placing it in...

Students explore and analyze the relationship of buoyancy and displacement needed to make an object float. They examine various boat designs, then design and build clay and aluminum boats that hold a cargo of marbles.

Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.
