There's more to melting than meets the eye! Junior physical chemists investigate the differences between specific and latent heats as a substance undergoes a phase change. Users remove heat from the system and observe changes in kinetic...

Be water wise! Science scholars learn the water cycle on a global scale in part seven of a 13-installment series. The hands-on interactive allows them to explore Earth's water storage, types of precipitation, and the cycling of water...

Go to extremes to illustrate boiling point! Junior chemists explore the effects of heating and cooling on polar and non-polar substances. The interactive allows users to raise and lower the temperature, set specific temperatures, and...
