Students determine that some liquids are able to evaporate more readily than others. They create a balance using cups and a ruler to determine which end of a strip dipped in alcohol or water evaporates the fastest, hence loses the most...

Students observe that water has weight and that weight decreases as water evaporates. The changes that occur as a sponge dries on a yardstick balance illustrates this concept.

Young scholars recognize that one source of drinking water is ground water located in aquifers. They create a model of an aquifer and summarize their experience in a report.

Students carry out an experiment to monitor diurnal fluctuations in dissolved oxygen, carbon dioxide, pH, and water temperature. They determine the CO2 and pH of the samples (and optionally, dissolved oxygen). Students complete their...

Students explore Squanto's contribution to the settlers. They plant seeds and follow instructions for water and fertilization. Students keep a record of the growth of the seeds. They write a paragraph that tells what they learned from...

Young scholars examine the differences between snow and rain. For this precipitation lesson, students measure one inch of rain and snow to calculate the amount of liquid water. Young scholars use a snowfall "conversion" chart to measure...

Pupils participate in an exercise/experiment designed to show how environmental pollution can affect the quality of drinking water.

High schoolers perform an experiment which will illustrate how to measure the approximate pH of chemicals in water using a pH indicator. They understand that a pH indicator is a chemical that changes color when it comes in contact with...

Learners observe one of the direct effects of acid water on plant growth. Students engage in an experiment which will take about 2 weeks. Learners will understand the effect that acid rain has on plant growth.

Students observe the effects of limestone on the acidity of water. Some areas of the nation have a lot of limestone in lake bottoms and in soil, which helps neutralize the effects of acid rain. Students see this effect first hand.

Students how islands form, rising water levels, growth of coral, and volcanoes. They complete Island Investigation worksheets after researching island formation on various Internet websites.

Students explore the structure and property changes of water through videos and classroom discussion. They are introduced to atomic arrangement of solids by looking closely at carbon in different forms, such as graphite and diamond....

Students participate in a hands-on activity to see how plants take up water and dissolved pollutants.

Students construct a thermograph for maximum and minimum temperatures for the 2-week period. They illustrate how the earth's atmosphere is heated by convection and conduction currents and evaporation of water.

Pupils discover how water moves through different types of soils. In groups, they use the same sample from a previous activity and empty it into a milk carton in which they have layered with cheesecloth to determine the percolation rate....

Students perform introductory swimming techniques. They review water safety rules. Students blow bubbles and put their head into the water. They touch designated body parts while standing in the water and finally touch the bottom of...

Students examine the three different types of soil and their physical properties.  In this soil lesson students design and implement a model of a water treatment plant. 

Students discuss and experiment with the phases of water.  In this phases of matter lesson, students recognize the different states of matter.  Students measure and record changes and understand when the state changes.

Students examine the influences of water and mulch on soil temperature.  In this investigative activity students complete a soil experiment. 

Students describe how the sun's rays produce colors. They describe how water causes the sun's rays of light to bend, producing a rainbow.

Students examine how each animal's habitat provides what that animal needs for survival. They discuss what an animal needs to survive-food, shelter, water, and space.

Students complete an experiment in which they demonstrate that air exerts a force. In groups, they create their own siphon and define air pressure. They estimate the time it might take to siphon various amounts of water. They collect,...

In this chemistry worksheet, students determine the number of water molecules is a given volume of water. Students determine the empirical formula for given compounds from the percentage mass of elements. This worksheet has 20 problems...

Students observe a scientific experiment and pose a hypothesis. For this scientific inquiry lesson, students make predictions about the combination of alcohol in water and how it will affect a floating ice cube.
