Learners experiment with inner tubes, weights, flasks, and pistons to demonstrate the gas laws. In this molecular motion instructional activity, students demonstrate pressure as a force per area. They conduct an experiment to show the...

Students develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Students review the characteristics of wetlands and list their benefits. After viewing short videos, they identify the organims that make their home in wetlands and how they have adapted. They compare and contrast the characteristics...

Students estimate the measurement in centimeters for common classroom objects. They check their estimations, discuss the differences and write a paragraph summarizing the activity.

Students take part in various activities ranging from creating a human clock, to small group problem solving to reinforce the concept of telling time accurately to five minutes on an analog clock.

Students participate in a paper folding activity that has them create a ruler for measuring to the closest 1/16th of an inch.

Young scholars build and apply concepts of geometry. In this geometry lesson, students create a building using proportions and scale drawings. They use Cabri technology to create a virtual drawing first.

Students construct using Cabri software. In this geometry lesson, students convert between units and apply the correct measurements to build objects. They create the room virtually and manipulate the shapes to the desired measurements.

Students discover the relationship between the sides of a polygon and the number of diagonals that can be drawn from one vertex, the number of triangles that those diagonals form, and the sum of the interior angles of that polygon.

Students test different sized marbles and how fast they can go. For this energy lesson plan, students test different sized marbles going down an incline. They predict which would have the most potential and kinetic energy. After the...

Students investigate the relationship between work and mechanical advantage. In this physics lesson, students calculate the work and efficiency of pulleys. They identify the different types of pulleys.

Eleventh graders study osteoporosis and understand the relationship between calcium and bone mass.  In this investigative lesson students participate in an activity in which they graph and construct basic bone biology.

Students study the attributes of liquids. In this science exploration lesson, students participate in a hands-on activity that requires them to examine the volume and shape of liquid.

Students measure shadows at different times of the day to determine when a shadow casts its longest and shortest shadows.

Students conduct an experiment. In this shadows lesson, students record the height of a meter stick. Students then cast shadows and record their length. Students compare the length of the shadow with the actual height of the meter stick.

Students correlate string tension with sound pitch. They describe how string mass (thickness) effects sound pitch and demonstrate an understanding of the physics of the acoustic guitar. They see that sound is produced by vibrations.

Pupils determine the force of a helium balloon that allows it to rise a specific distance.  In this helium lesson students calculate the amount of paper needed to construct a weight and determine the density of a piece of paper. 

Learners are able to identify the units associated with linear work. They are able to calculate the work done on an object. Students discover how the force exerted on an object and the distance the object moves determines the work done...

Students explain basic principles of aeronautics such as gravity and lift. In this How Things Fly lesson, students visit the interactive, hands-on How Things Fly gallery at the Smithsonian. Students perform three experiments that...

Students keep a food diary for a day and examine the calories, and nutrient intakes.  In this food diary lesson students complete several activities including a food diary analysis. 

Third graders practice measuring different objects. They discover the concepts of ratio and proportion and practice converting numbers into the correct unit. They read stories as well to help them with the concepts.

Students investigate how mass affects the speed of an object. For this physics lesson, students record data on the data table and graph results. They analyze findings and formulate a conclusion.

Students analyze velocity and how it is determined. They experiment with velocity in order to measure and calculate the magnitude of speed. They use examples in their novel "Skateboard Renegade" to relate velocity to real life situations.

Students conduct an experiment to observe the properties of both salt and freshwater. They explain why freshwater will stay at the surface while salt water will travel up a river bottom because of density. Students also research the...
