Without water there would be no life on this planet. Biology learners find out why by reading this handout. Create a worksheet of questions to answer after the reading. Follow it up with quick demonstrations or laboratory activities that...

How can you effectively provide detailed concepts of water properties to your high school class in a way they find exciting and challenging at the same time? By letting them play, of course! Through a variety of...

Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The lesson plan is...

Learners develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

Through three activities, first-time physical scientists wonder at the properties of water. Freeze some soda cans and a container of water prior to the investigation to show that water expands when frozen. Lab groups experiement with...

Students use video, Internet research, graphs and tables, worksheets and hands-on experiments to investigate the properties of water in a lake environment. They work under direction or through an inquiry process.

Sprouting scientists explore the concept of density by making mass and volume measurements for five different liquids. From these measurements, they calculate densities. They apply their learning to explain Galileo's thermometer works...

Students investigate water pollution. They develop an understanding of the behavior of organisms, of the structure and properties of matter, and of natural and human induced hazards by conducting lab tests. They present their data...

Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

Here is a great way to get pupils to express a scientific concept in a fun way. After hearing the story of Walter the Water drop and learning facts about the water cycle, the class will write a creative expository piece describing what...

Playing with balloons, water, oil, and bottles help put this lesson over the top! Participants use air-filled balloons in water tanks to experience gas compression. They also use oil-filled bottles to experiment with buoyancy. Included...

Learners investigate quality of water in a stream, lake, or pond by examining chemical, physical, and biological characteristics.

Help your classes feel like they can walk on water! An engaging inquiry-based lesson has young scholars experiment with different surface coatings. They make observations about their properties and how they relate to the surface tension...

How do we clean up oil spills and other pollutants in the water? Explore water treatment strategies with a set of environmental science experiments. Groups remove oil from water, work with wastewater treatment, and perform a water...

Students study the flow of water in the environment.  For this water cycle lesson students evaluate the consequences of changes in the water cycle using data. 

Sixth graders work together to complete an experiment about the quality of freshwater. In groups, they collect fresh water samples from a variety of sources and test the pH levels. After completing a KWL chart, they test the amout of...

Students explore hydrology concepts. In this environment and biology lesson, students identify and describe macroinvertebrates using a variety of pictures and resources. Students observe and write about a classroom aquarium in which...

The goal of this science lesson is to have youngsters be able to identify the physical and chemical changes in the carbon cycle, and water cycle due to weathering. The in-class inquiry/experiment is quite interesting and easy to...

Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

Understand how chemical reactions recombine atoms to create the "chemicals of life". An experiment, showing the basic chemical reactions of an iron nail or a match, helps young children start their understanding of permanent changes.

Students are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during the...

Certain materials do not always maintain the same physical properties when they exist in the nanoscale. Help your classes to explore this idea through an experimental lesson. Scholars use spectroscopy with samples of silver solution...

Learners examine the process of photosynthesis; its products and reactants, and the sequence of the process. They diagram the light reactions, record observations of plants, and discuss how difficult it is to measure plant growth as it...
