Exploring Energy
When asked to list everyday objects that require energy, most people list technology that use batteries or electricity. Through hands-on exploration, young scientists discover energy is much more than just circuitry. They play with...
Concord Consortium
Diffusion Across Semipermeable Membranes
Mitochondria use two semipermeable membranes to work properly. Young scientists adjust the pore size for two membranes. They then observe the diffusion of two different sizes of molecules.
