Life science learners investigate live cells. They examine wet mount slides of cyanobacteria and Elodea plants. They peer into the dynamic microscopic world of protists. Afterward, they construct a model of a cell, including rudimentary...

Junior geneticists construct models of DNA to discover sequencing and pairing of nucleotides. They use the models to simulate protein synthesis and then translate the codes into physical traits. Finally, they use the traits to create a...

Investigators use indirect evidence to guess what is occupying a sealed box. You could also use a set of plastic Easter eggs to encase the unknown items. Another terrific activity involves having students drop a pencil on a sheet of...

Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...

Science learners scrutinize shadow size and quality, and experiment with diffraction. They model superposition of electromagnetic waves, and experiment with interference. These activities are action-packed and challenging for your...

Venture into the world of macromolecules with three exciting, distinct laboratory activities. Young chemists examine the forms of carbon and discover how they are associated with atomic arrangement, construct models of carbon-containing...

An introductory exploration of the nature of light is provided via activities and demonstrations. Science superstars observe various light sources, learn how to apply inverse square law, and practice using a light meter. Follow-up...
