Students will make a car powered by an elastic engine. Introduction Rather than converting chemical energy to kinetic energy like your family car, this car (adapted from http://pbskids.org/designsquad/projects/rubber_band_car.html) ...

Students use yeast to explore CO2 production by living organisms. This is an excellent opportunity for students to design their own experiments to determine which variables affect the yeast's ability to ...
... of the arch. At the ground, strong supports, or abutments, keep the arch from moving outward. Architecturally, the dome is one of the strongest designs because it supports the weight of the roof evenly ...
... students design, evaluate, and suggest improvements for a container that will protect their precious payload: an egg. There are three basic ways to increase the likelihood of safely dropping an egg: ...
In this activity, students design a series of challenges to test their body's performance in a variety of ways. Human Performance Challenges Introduction The human body is an incredible machine. ...
This activity is designed to get students thinking about what happens when air moves. Sometimes it is difficult to think about air and what it does because it is invisible. The air cannon is a way to 'see' ...
... Thrust and lift are artificially created forces used to overcome the forces of nature and enable an airplane to fly. The engine and propeller combination is designed to produce thrust to overcome drag. ...
In this activity, students assess the physical features that make it possible for birds to fly. Introduction Humans are not physically designed to fly. We cannot create enough lift to overcome the ...
... wings come in a variety of designs. What they all have in common is that air is made to flow faster over the wing's top surface than under the lower surface. This is mainly accomplished by an upward tilt ...
... slips smoothly through the air since its shape produces little drag. A flat piece of paper has more surface area opposing thrust, which produces more drag and slows it down. Planes are designed to ...
In this activity, students design and compare different kinds of paper airplanes to determine which results in aerodynamic flight.  Introduction What makes a paper airplane fly? Air. How easily ...

In this make and take, students exploit the force of drag to make a parachute that will drop as slowly as possible to the ground. They are encouraged to modify their model to find the design that is the ...
Use some rather unique building materials to design and build a structure which is strong enough to support a book. Then try out different base shapes and see what happens! HOW STRONG IS YOUR HOUSE? ...
