Heat Engine
How can heat power an engine? Scholars observe a heat engine working and control variables to determine the most efficient setup. They change the amount of heat input as well as the stroke length. Energy efficiency numbers prove the...

Particle Tracks
Did you know physicists can identify new particles by observing the path they take in a particle accelerator? Scholars explore the variables that determine the direction and radius of the circular path different particles take. They...

Which Tape is Stickiest?
Students conduct an experiment to determine which style of tape will stick the best. In this controlled experiment lesson, students predict which tape will stick best to a marble that rolls over it, then they conduct the experiment...

Using Graphs to Compare
Pupils use the FoilSim computer simulation program, and demonstrate an understanding of the lift variables by explaining their graphical representations. They demonstrate an understanding of forces and motion.

Stow Lake
Does the depth of a pond matter to the waves created when rain is falling? Many people assume the answer is no, but interestingly, it does matter. Pupils explore this concept and other variables related to wave behavior through a...

Investigating Velocity Effects at Takeoff
Young scholars use, with increasing confidence, problem-solving approaches to investigate and explain mathematical content. They make and test conjectures. They use tables and graphs as tools to interpret expressions, equations, and...

Newton's Apple
Scientists state that the higher something is above the earth, the greater the gravitational potential energy. Does this mean there is more gravity acting on the moon than on an apple falling from a tree? Scholars adjust the distance...

What's The Big Deal About Accutane?
Young scholars take on the role of epidemiologists. They investigate an "outbreak" in serious birth defects that occur in infants born to teenage girls. students discover a link between the use of the acne drug called Accutane and birth...

Reading Trees: Understanding Dendrochronology
Students 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.

Design of Airfoil for Given Lift
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...
