Fifth graders draw a plan that they think will clean the sludge in a jar. Students construct the treatment system they designed, take a bottle of sludge to the system and try it out, writing down what happened.

For this science worksheet, students find the words that are needed for the acquisition of vocabulary and the answers are found at the bottom of the page.

Students are able to describe the importance of wetland vegetation. They describe the impacts human activities have on water systems. Students compare and contrast the effect of different soil types on water filtration.

In this water in the environment activity, students match 10 terms related to water to their definitions. They identify 10 sentences as true or false related to groundwater, layering and landfills. They fill in the blanks for 2 sentences...

Students conduct experiments to study the quality of water. They examine how pollutants get into and affect the water supply in this unit.

Learners brainstorm the different characteristics of potable water. In this general science instructional activity, students test several water samples and hypothesize which samples and brands they are. They discuss where drinking water...

Fifth graders examine what contaminated water looks like, and how it becomes polluted. They examine a teacher demonstration of water is not polluted but does contain rocks and other things that do need to be cleaned out before drinking...

Students determine the presence of drugs in water. In this chemistry lesson, students experiment on water samples using thin layer and column chromatography. They determine the concentration of drugs present using graphical analysis.

Students design and construct a water filter using activated carbon, cotton and other materials to remove chocolate powder from water. They test and record their observations, and complete a KWL chart.

When nature calls, you need to answer. Physiology learners discover that it is a just your body's way of regulating pressure and water content. Along with osmoregulation, they also examine thermoregulation, two vital processes with which...

In this word search worksheet, students locate 20 words related to science. The word list includes volume, mixture, and solute.

In this recognizing different types of changes worksheet, students answer questions about such things as reversible change, irreversible process, climatic change, filtration process, physical change, and change in the state of a...

Students observe a precipitation and neutralization reaction and learn to filter the products of the precipitation reaction. In this precipitation and neutralization lesson plan, students create curds and whey using milk and vinegar....

Fourth graders simulate filtration of water containing contaminates to determine how nature cleans water. They make predictions, report observations, and construct reasonable explanations concerning their outcomes. then connect this to...

Fifth graders play a game in which they list as many environmental issues or terms in alphabetical order. They brainstorm ways they can save the environment and create a mural that displayed research found from the internet and Encarta.

In this biology worksheet, students look at the function of filtering in the nephron of the kidneys and the biochemistry is emphasized.

Your class will learn all about the function of the kidney and how  it operates in animals from different habitats.  The methods of absorption, filtering and excretion are detailed and pupils will learn of the different...

What is a reasonable percent yield in the manufacturing process? Scholars develop a process for producing chalk in the third lesson of a six-part series. Then, they must determine the theoretical and percent yield. Discussions about...

Elementary schoolers who are learning about filtration and mixtures could use this activity to gain practice in filtering techniques. In it, they are asked how to manipulate a container in a way that would lead to properly filtering...

Almost 200 slides make this a vast collection! It is a quirky collection, titled "Marine Fisheries Management," but having little to do with that occupation. What you will find are two-toned blue backgrounds with no pictures, but a few...

High schoolers examine the water cycle and the factors that interact with watersheds.  In this watersheds lesson students describe the purification process, trace the flow of infiltrate water through aquifers, and research the...

Young scholars examine environmental change of land, water, and air, discuss Clear Skies Legislation, and experiment on solid compaction and resultant water filtration.

Students examine soil. In this soil composition lesson students participate in soil sedimentation and filtration activities. The students discuss what non-living and living things are in soil and why it is so important.

In this leaching landfills worksheet, learners conduct an experiment by following the procedures, observing the results and discussing the conclusion about how garbage leaches into our water.
