Young scholars explore the effects of aquatic trophic relationships on water transparency. They observe and explain the effects of reducing nutrient inputs on agal density on water transparency.

Students examine the Magnus effect and its history.  In this forces lesson plan students investigate the lift of a rotating cylinder.      

In this Earth's atmosphere worksheet, students observe the effects of air pressure using an egg. They describe what happens to the egg and what makes it do what it does. Then they determine how to get the egg out of the bottle opening at...

In this liquids and gases instructional activity, high schoolers review 9 vocabulary terms associated with liquids and gases by completing a crossword puzzle.

Fifth graders use various strategies to find the area of land, the area of forestry and the population of Japan and the US. In this size per unit lesson, 5th graders explore how to figure ratio. Students draw pictures to...

Students investigate how temperature and salinity causes ocean layering. For this ecology lesson, students observe and sketch their experimental result. They report their findings in class.

Students experiment with floating the spaghetti, the gas functions like a life preserver. Pupils comprehend that a person is slightly more dense than water. They comprehend that a life preservers are made of low-density materials. The...

Pupils explore biological impact by completing a worksheet in class. In this animal population lesson, students utilize river rocks and jars to conduct a coqui frog population role play activity. Pupils define a list of amphibian related...

Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Present the class with a question on whether the water level of a pond will rise they take a large rock out of a boat and drop it into the pond. Groups come down on all sides of the question and try to justify their answers. The activity...

How does a hot air balloon fly? An experimental lesson has scholars build a balloon from a garbage bag and monitor the movement of air. As the temperature of the air in the balloon increases, gravity moves the denser cool air down,...

Groups use a marble to determine the viscosity of household fluids. The procedure calls for pupils to measure the amount of time it takes a marble to fall a specified distance in the fluids. Using unit conversions and algebra, the teams...

Students separate plastics according to their densities, develop a method for separation and identify variables in an experiment and a fair test, changing only one variable at a time for a fair comparison. After testing, they develop a...

Fifth graders investigate buoyancy by conducting a science experiment.  In this water properties lesson plan, 5th graders predict which of their different paper boat designs will float for the longest period.  Students conduct...

Learners perform an experiment to determine the stomaltal index on the upper and lower epidermis of two species of leaves. Stomatal densities change in response to changing atmospheric levels of carbon dioxide and to annual rainfall.

Students construct their own lava lamp using simple substances. In this physics lesson plan, students explain how difference in density causes convection. They solve for forces and buoyancy using mathematical equations.

Students, in this experiment, collect leaves from two species of trees and the stomatal index on the upper and lower epidermis of each leaf be determined.

  Students build boats out of clay to test the buoyancy of the boat in water.  Students break into pairs and construct their boat to specific guide lines, then experiment with their boat in the water.   

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

Students observe a demonstration on the role of thermal conductivity in heat transfer.  For this thermal conductivity lesson, students design and conduct an experiment to compare the thermal conductivity of four substances....

Young scholars 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.

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...

In this moon's atmosphere worksheet, learners read about the tenuous lunar atmosphere and solve 4 problems. They find the density of helium particles, they find the grams of given atoms in the moon's atmosphere and they find the volume...

Students conduct a variety of experiments to explore gel electrophoresis. In this biology lesson, explain how this process separate DNA and RNA. They discuss the practical applications of this method.
