How's the Air Up There?
Students experiment with soda cans and water to discover why air pressure is greater closer to Earth's surface.
Curated OER
What's it Like Inside the Sun?
Students perform experiment in which they model convection as it occurs in our Sun. They also explain that convection acts where the effect of gravity and heat are present (low density fluids can rise and cool, and high density fluids...
Curated OER
Water and Ice
Learners investigate what happens to solids and liquids when they change from one form to another. The amount od space taken by frozen water begins the discussion and students are led to formulate their own hypothesis to research.

Float My Boat
Fourth graders, in groups, experiment with density and the displacement of water by creating and designing their own boats and seeing which boat holds the most centimeter cubes without sinking..
Curated OER
Icebergs Ahead!
Students experiment with density of ice, and examine how density affects how icebergs float in water.
Curated OER
Wind Dynamics and Forests
Students perform experiments to explore differences in wind speed and forest density. Through experimentation and observation, students realize that changes in vegetation affect the atmosphere and wind conditions. They create a model...
Curated OER
Boy, Is That Buoyant!
Fourth graders see that salt increases the density of water and creates a condition wherein objects are more buoyant than would be expected under normal conditions. They describe the relationship between heat energy, evaporation and...
Curated OER
Self Portrait, What Nerve!
Students conduct an experiment to determine the distance between touch receptor fields in parts of the right-hand side of the body. They enter data into the data table.
Curated OER
What is an Estuary?
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.
Curated OER
Herb is the Word
Middle schoolers conduct an experiment to determine how different soils affect plant growth over a six-week period. After determining the physical properties of different types of soil, students plant various types of seeds into the soil...

Detecting Magnetic Materials in "Martian" Soil
Pupils simulate some of the Pathfinder experiments by devising methods of collecting and measuring magnetic substances in pseudo-Martian soil. The efficiency of each of the methods used to collect materials is evaluated in this...
Curated OER
Population Dynamics of Growth of Drosophila
Students experiment with Drosophila to determine if density of female flies, food sources, temperature and light affect the population dynamics of growth. Students graph their data and compare their results to the number of human...
Curated OER
STABLE ANGLES OF SLOPES
Students conduct an experiment using soil and shoeboxes to explore factors controlling and affecting the slope of a hillside. They analyze angles, surfaces, etc. to gain an understanding of instability of slopes.
Curated OER
What Floats Your Boat?
Learners discover the Archimedes principle through a buoyancy experiment. They measure the water displacement of a lump a clay which is denser than water then reshape the clay into a bowl which floats but displaces more water.
Curated OER
Changes Inside Planets
Students investigate the concept of planetary differentiation. They complete an experiment to simulate it using gelatin and food. The lesson includes vocabulary to increase reading comprehension skills as part of the inquiry. The lesson...

Bell Live! The Great Lakes: A Superior Adventure
Students participate in a virtual field trip to Lake Superior. In groups, they perform experiments in which test the level of toxins and bacteria in the water. They also watch video segments life in the lake and discuss their observations.
Curated OER
Earth History Part II
Eighth graders hypothesize what caused the break up of continents. In this earth science lesson, 8th graders study about the events that took place during Mesozoic and Cenozoic Era. They reconstruct a supercontinent and report their...
Curated OER
Emulsion_ Compulsion
Students experiment with common household products to determine the properties of emulsions and how they fit into the classifications of matter through this series of lessons.
Curated OER
What's the Matter with My Jell-o?
Students work in teams of four as they conduct four controlled Jell-O experiments over a two-day period. The Family Page extends this learning to the community by providing families with challenges to explore at home.
Curated OER
Not a Drop to Drink
Students design an experiment to determine which liquid is water. In this chemistry lesson, students perform the experiment as outlined in their design. They record observation and formulate conclusion.
Curated OER
Thermo and Fluid Dynamics of a Homemade "Lava Lamp"
Students construct their own lava lamp using simple substances. In this physics lesson, students explain how difference in density causes convection. They solve for forces and buoyancy using mathematical equations.
Curated OER
The Sun as the Driving Force of the Water Cycle
Students study the water cycle and how the sun is an important factor. In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.
Curated OER
What's Matter?
Students explore many of the basic properties of matter including atoms, ions, elements, molecules, and density. The class explores an interactive flash-animated Web site to answer questions and clarify misconceptions they might have had...
