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...

Now this is a clever approach to familiarizing aspiring astronomers with the phases of the moon! They first record the specific dates for ten special events in their lives. Then they use an online moon phase calendar to find out which...

Adolescence and teenage years are very difficult in terms of emotions, primarily due to the amount of change going on in growing teens' lives. Guide middle schoolers through disruptive changes and transitions with a set of activities...

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...

The speed of a dragonfly brings math into the real world as your learners collaboratively see the value in calculating unit rates in direct proportion problems. This six-phase lesson encourages you, as the teacher, to only ask questions...

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...
