Discuss the availability of clean, plentiful water and the causes of water pollution. In groups, sixth graders discuss problem-solving methods for keeping water clean. They explore the function of water treatment plants and perform...

Students explore the causes of water pollution. In this environmental lesson, students conduct experiments with natural filtration systems.

Do some experimentation with reduction-oxidation! Stoichiometry superstars use a single-replacement reaction to study limiting reactant, theoretical yield, and the reactivity of metals through a lab activity. The teacher's guide includes...

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.

Students experiment using the basic principles of gel filtration. They use the gel filtration technique for testing for the presence of specific substances. Students discover that starch is a larger molecule than glucose.

Immerse your chemistry class in the world of organic chemistry! Science scholars isolate acetaminophen from an over-the-counter sample during an intense and interesting lab. Groups use many different separation and analysis techniques to...

High schoolers make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Students investigate the concept of a filter. They use simple supplies in order to construct one after watching a demonstration performed by the teacher. An important warning that the project water is not clean for drinking is included....

Avoiding lab safety rules will not give you super powers. The lesson opens with a demonstration of not following safety rules. Then, young chemists practice their lab safety while finding the mass of each item in a mixture and trying to...

Students write and balance five chemcial equations which have been observed throughout the process of completing the experiment. They use vacuum filtration to recover suspeneded particals from a colloidal suspension. Students correctly...

Students explore techniques used to filter water and different pollutants. In this prevention of water pollution lesson plan, students define water pollution and list ways water is polluted. They explore water purification and complete a...

For this thermal decomposition of calcium carbonate learning exercise, students perform three experiments on calcium carbonate, make observations, and write the equations for each reaction. Students explain in detail what happened at...

Students perform two experiments to show the properties of enzymes. They use pectinase to produce apple juice from applesauce to show enzyme action and then taste the difference between raw and boiled papaya seeds as evidence of enzyme...

Fifth graders design an experiment in which they separate mixtures. In this mixtures lesson, 5th graders define mixtures, solutions, solutes, and solvents. They watch a video, complete worksheets, and perform an experiment to separate...

Students examine how river travel affected the Lewis and Clark expedition. They define gravity, slope, and velocity, conduct a river formations experiment, complete an activity sheet, and watch a video about Lewis and Clark.

Students examine how water is treated prior to becoming available for human consumption. In this water treatment lesson plan, students conduct an experiment in which they filter water. Students formulate a hypothesis, test, analyze data,...

Students investigate the need for filtered water. In this filtered water instructional activity, students explore the health hazards posed from consuming unfiltered water. Students construct a water filtration device.

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.

Students perform simple experiments to show properties of enzymes through studying how apple sauce can turn into apple juice and experimenting with papaya seeds. Students witness how enzymes speed up reactions through witnessing the...

Learners work together to perform simple experiments discovering the properties of air. They share their results with their classmates. They examine how engineers use the properties of air to clean the air of pollutants.

Students explore mixtures and compounds. In this lesson, students do an experiment to distinguish between mixtures and compounds. Students complete ten different phases of the experiment testing many different substances. Students will...

Learners explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also discover several things that engineers are doing to...

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