Working in teams, students learn the basics of fluid power design using the PFPD as their investigative platform. They investigate the similarities and differences between using pneumatic and hydraulic power in the PFPD. With the main components of the PFPD already assembled, student groups determine the correct way to connect the valves to the actuators using colored, plastic tubing. Once connected, they compete in timed challenges to test their abilities to separate material out of containers using the PFPDs. NOTE: No special pre-requisite knowledge is required for students to be successful in this activity.

Pumps are used to get drinking water to our houses every day! And in disaster situations, pumps are essential to keep flood water out. In this hands-on activity, student groups design, build, test and improve devices to pump water as if they were engineers helping a rural village meet their drinking water supply. Students keep track of their materials costs, and calculate power and cost efficiencies of the prototype pumps. They also learn about different types of pumps, how they work and useful applications.

To explore different ways of using solar energy, students build a model solar water heater and determine how much it can heat water in a given amount of time. Solar water heaters work by solar radiation and convection.

The sodium/potassium pump is a good example of active transport of molecules across a membrane. In this example, active transport is coupled to ATP hydrolysis to obtain enough free energy to transport the ions against their concentration gradient. This ion pump is an example of antiport membrane transport, where the transported molecules are pumped across the membrane in opposite directions (as opposed to synport). The sodium gradient is generated for use by cotransport systems, such as the active transport of glucose from the extracellular environment into the inside of the cell. The non-equilibrium state of the sodium gradient is essentially free energy to be used for the import of molecules against their own concentration gradient.
