Students watch a video clip about German submarines lost during World War II. They work together to create their own submarine out of a plastic bottle. They test the buoyancy of the submarine in different activities.

Students form hypotheses and carry out an investigation in order to answer a central question: Does soap float? The focus of this lesson is on scientific inquiry, but it incorporates scientific topics such as sinking and floating.

For this thermochemistry worksheet, students answer questions based on the reaction of charcoal and liquid oxygen. Students write a balanced chemical equation, determine the limiting reagent, calculate the mass of each product, and...

Learners investigate safe laboratory procedures, classroom management guidelines, and group roles and procedures. They study a set of safety guidelines with their parents, and to sign a contract stating that they understand the...

Learners will explain the Archimedes's Principle. In this instructional activity on plankton, students will describe three factors that can affect the buoyancy of plankton. This instructional activity contains extensive background...

Learners explore to investigate if the distribution of Purple loosestrife around the school district area is relevant to its distribution and control. They create a comprehensive map to support their thesis and data and then head out...

Students explore an estuarine system to gather data on density driven currents. This type of current is contrasted with temperature and wind driven currents.

In this currents worksheet, students review the Coriolis effect, surface currents, and density currents. This worksheet has 8 short answer questions.

Students identify the physical and chemical properties and explore the differences.  In physical and chemical property lesson students test polymers for the differences between the physical and chemical properties, record their...

Covering both permeability and porosity, scholars perform a hands-on experiment testing various soil types. The material includes a pre-lesson worksheet to help focus pupils on the task at hand. 

Students define the terms estuary and watershed. They conduct an experiment to determine the density differences between fresh and saltwater. They examine the salinity distribution of the Peconic Bay Estuary.

High schoolers collect chemical, physical, and biological data from a local lake throughout the year. In addition, students discuss the design of an experimental structure for water collection at several specific depths as well as assess...

Third graders explore the difference between a physical change in a substance and a chemical change. students study the volume, density, altering shape and chemistry of a copper penny.

Sixth graders read Hatchet by Gary Paulsen, discuss refraction, identify example of it from novel, and perform classroom experiments demonstrating refraction and reflection.

Students use plastic bottles, water, and condiment packets to simulate how natural gas comes from decaying ocean plants and animals. In this natural gas lesson plan, students also fill out lab packets and answer exit questions.

In this thermodynamics worksheet, learners read about conduction, convection and radiation. They answer 47 questions about heat transfer, thermal equilibrium, insulators, conductors and the states of matter.

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.

Learners examine what lies within the Earth. They research and create scale models illustrating the layers of the Earth and write skits advocating a travel plan to send a probe into the Earth's mantle.

Students forecast future population growth of the U.S. Virgin Islands. In this U.S. Census lesson plan, students explain the factors that influence population density on the U.S. Virgin Islands, including geography and economic activity.

Students explain the impact of glacial melting to global climate change. In this environmental science lesson, students design an experiment to investigate the effect of salinity change to melting glaciers. They share their results to...
