Help your class determine the types of pollutants coming from vehicle exhaust. Groups use an air quality monitor to determine the emissions from different vehicles, to gain knowledge about combustion energy, and to predict how the...

When going for distance, does it make a difference at what angle you launch the rocket? Teams of three launch foam rockets, varying the launch angle and determining how far they flew. After conducting the series of flights three times,...

How high did the ball go? Engineering teams build a working pneumatic system that launches a ball into the air. The teams vary the amount of pressure and determine the accompanying height of the ball. An extension of building a device to...

Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the...

Following detailed directions, teams collect the voltage and current outputs of a photovoltaic cell by adjusting the resistance. Using the collected data, they determine the highest power output. Implications for weather and a large...

Sugar isn't good for you, but it's great for yeast! Scholars design an experiment to investigate how variables affect the rate of sugar consumption in yeast. The last installment of a nine-part Life Science unit considers how scientists...

Accept NASA's challenge to design heavy lifting vehicles. Groups of three design balloon-powered rockets to carry as much payload to the ceiling as possible. The teams are encouraged to launch several times while making...

Physical science juniors will enjoy this sensational enrichment on aerodynamics, especially if they are also sports fans! With a focus on physical features and behaviors, collaborative groups make observations on five different golf...

Collaborative groups connect resistors and solar panels in series and measure electrical resistance, voltage, and current. The objective is to order 16 solar panels from strongest to weakest. They graph current-voltage and power curves...

Drop a perfect project into your lesson plans. Groups use different building materials to create models of parachutes for food drops. After testing out their prototypes, they make improvements to their designs.

Learners identify and implement methods to standardize testing stations that measure solar panel output power. After collecting electrical ouptut data from several solar panels, they plot the current-voltage and power curves. Students...
