Explore terminology related to water droplets. The sixth installment of a nine-part series teaches young scientists about wetting and contact angles between water droplets and surfaces. It also distinguishes between hydrophobic and...

Scientists could measure the diameter of the sun before they knew its distance. Scholars construct a simple mirror box to measure the diameter for themselves. They compare this measurement with the official size, listed in a...

Discuss Archimedes' Principle and fluid forces with your young scientists as they describe the relationship between mass, volume, and density during a series of engaging activities. They use the Participle Theory of Matter to explore the...

Historians have proven that as early as 1497 skilled navigators were using a kamal to sail across oceans. Scholars learn about navigation tools and astronomy before building their own kamals. They then learn how to use it to determine...

Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

Experiment with optical resolution using an inquiry-based lesson plan. Young researchers calculate fellow classmates' optical resolutions. They apply the information to understand the inner workings of optical instruments.

Young classes are sure to get a charge out of this lesson plan! Learners experiment with circuits of a solar cell. They practice determining current, voltage, and power for the circuit and maximize the voltage and current of the cell.

Don't let all your hard work go up in smoke. Pupils conduct an experiment to see the harmful effects of cigarette smoke. They observe how smoke changes the color of white wool and an indicator solution.
