Splitting Water with Electricity
Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.
Curated OER
Water Cycle
Young scientists explore Earth elements by conducting an experiment. They define water vocabulary terms such as condensation and precipitation. In addition, they conduct a water experiment in which they build a terrarium, so they can...

Seashore Explorers
There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...
Curated OER
Disappearing Water
Students explore the water cycle. In this earth science lesson, students observe and measure water in a closed container and in an open container. Students record their observations and compare their sets of data to draw conclusions...
Curated OER
Water and Ice
Students explore water and how it changes forms. In this investigative lesson plan students participate in an activity that shows them how water changes form and what it looks and feels like.
Curated OER
Walking Magic
Young scholars conduct experiment with water striders by placing the insect in two different solutions and discuss their observations. They discover that weight and surface area are important factors in their experiment.

Exploring the Lotus Effect
The Lotus Effect ... is it not some kind of yoga pose. In the last installment of a nine-part series, young scientists observe the Lotus Effect on lotus leaves and water-repellent cloths. They observe how motion and damage affect the...
Nuffield Foundation
Investigating the Effect of Temperature on the Activity of Lipase
How does temperature affect lipase activity? Young scholars conduct an experiment to collect data on the interaction of lipase at different temperatures. They add lipase to a solution of milk, sodium carbonate, and phenolphthalein and...

Properties of Water with a Splash of Color
Young scholars explore the properties of water. In this cross curriculum art and physical science instructional activity, students experiment with a variety of materials to demonstrate the cohesive forces and adhesion of water. Young...
Curated OER
Surface Water and Groundwater
Students examine distribution of water and minerals. In this surface and groundwater lesson, students conduct an experiment with fresh and salt water making hypothesis and drawing conclusions about minerals.
Curated OER
Water and Ice
Students observe and discuss what happens when water turns to ice and when ice turns into water. In this freezing and melting lesson plan, students observe ice and water and complete hands on activities that change their properties.
Curated OER
Water Cycle Activity
Students build a model and observe the cycle of evaporation and condensation that occurs in the water cycle. They see how the water cycle works, such as water condensing on the side of the jar and drops precipitating into rain that...
