Measuring with water

Measuring volume can be a mystery for 5th graders, but this hands-on activity gives the gift of discovery. The volume of simple rectangular solids and irregular shapes are calculated through various methods including displacing liquid in...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

Students investigate the water cycle by performing a simple hands-on activity using a plastic container, plastic cup, a rock, and a reflector lamp. They observe the model and measure the water level from time to time.

Before your learners excuse themselves to get a drink at the water fountain, prompt them to think about where that water comes from. A middle school science instructional activity encourages groups to research their community's source of...

Your class sets up a mini water cycle model to examine the process. Then they watch an animation, following a water molecule through the cycle. A well-developed lab sheet guides learners through the lesson and a PowerPoint presentation...

We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity. 

Students perform an experiment to measure the density of tap water vs. salt water.

Learners explore the water cycle and associated phase changes. They predict what happens to the mass of an ice cube in a Ziploc bag, discuss and act out phase changes and diagram the water cycle.

The goal of this collection of lessons is to make middle schoolers more aware of the ways in which they are dependent upon water to maintain their standard of living. Learners compare water use in Lesotho to water use in the United...

Did you know you can conserve water by drinking tea instead of coffee? Learn about other products that use larger amounts of virtual water in an online lesson. Pupils complete a series of questions to test their understanding of the...
