Students work together to collect soil samples from different locations. In the samples, they identify the macroorganisms and classify them. They identify the conditions that affect how macroorganisms grow. They also analyze and identify...

Students investigate seed germination. For this lesson on scientific prediction, students conduct a scientific experiment using oat seeds.

Students discover the basic principles of aerodynamics, including the roles and identity of natural forces involved. They examine how the force of gravity is overcome by the curved shape of an airplane wing and air pressure.

Students explore the relationship between the force applied to a spring and its stretch. They design and conduct an experiment to determine the stretch of spring with 15N of force without having an actual 15N mass.

Students use FoilSim to design an airplane wing that generates a given lift. As they change parameters such as airspeed, altitude, angle of attack, thickness and curvature of the airfoil, and size of the wing area, the software...

Young scholars examine tree-ring dating and discuss the lack of water the settlers in Jamestown faced. They create paper tree rings, simulate rain patterns, and describe the history of construction paper tree sequences.

Students investigate the problem of osmosis by conducting an experiment. They use eggs with the shells dissolved to tell whether fluid can move across the membranes. The experiment provides high interest for all kinds of students to keep...

Students investigate the concept of lung capacity. They use flow meters to measure the maximum capacity of themselves and others. The data is collected in order to make some conclusions concerning the mean of individual lung capacity....

Seventh graders demonstrate scientific inquiry to design and perform an experiment involving Grow Creatures. They participate in a class discussion, and in small groups design an experiment that determines how to change the materials to...

Students study the radial solution of hydrogen activity. They illustrate eigenvalue problems in applied mathematics. Students explore Schrodinger's equation and particle wave duality.

Students use Curveball to complete the activity to determine how the speed of airstreams changes in relation to changes in the distance of the airstream from the center of the baseball.

Pupils use FoilSim to complete the activity and investigate the factors that affect lift and how wing area and lift are related.

Students design an experiment to analyze the timbre of different instruments. In this physics lesson, students analyze the missing quality in sound. They discuss their results in class.

Students use FoilSim interactive software to become familiar with the way in which the flow of air across or around an airfoil affects its ability to create lift.

Students, through the use of the Curveball interactive software package, become familiar with the way in which the flow of air across or around an object affects its ability to lift, spin, and curve. After reading the explanation given...

Students investigate the area under a curve and the rate of change.

Ninth graders, after reading the explanation given below, complete the problem-solving activities to demonstrate an understanding of the concepts presented.

Learners read an explanation from a NASA Web-based textbook, then demonstrate an understanding of the text by using it, along with FoilSim, to complete an activity that manipulates the lift coefficient equation.

Learners read an explanation from a NASA Web-based textbook on lift and an explanation on the FoilSim software package given below. They use FoilSim to evaluate the relationship between wing area and lift.

Students, after reading an explanation on lift from a NASA Web-based textbook and an explanation on the FoilSim software package given below, use FoilSim to evaluate the relationship between velocity and lift.

Third graders complete a diagram of the revolution of the earth around the sun and write a one paragraph explanation of the factors that cause seasons.

Fourth graders explore the earth's revolution around the sun and the changes in weather that follow this motion.

Students create and conduct various experiments to determine the origin of a family artifact, and then determine whether their results were successful. Students summarize their results and evaluate whether their hypotheses were correct.

Students explore the skills and information needed to complete a science fair project. They follow guidelines to create an document their science fair project.
