Students examine samples of water to determine its cleanliness. They visit a waste treatment plant and/or reservoir. Students explore what protects the water supply from contamination by chemical or organize pollution. They trace the...

Students observe methods by which air can crush aluminum cans. As water in the can boils and is sealed, the can collapses as it cools. When the procedure is reversed, the can expands to its original shape. After the alternate experiment,...

Third graders investigate how water is released from different plants into the atmosphere. They observe and investigate two types of plants with domed lids with condensation and communicate those observances and inquiries on an in-class...

Pupils study the benefits of reservoirs while locating and identifying water sources that flow into Tuttle Creek Reservior.

When presented with three unopened bottles of water, students are asked to tell decide which one is contaminated with a microbe. Students work in small groups and role play being a Microbiologist, a patient, or a recorder. The patient is...

Third graders investigate the concept of bodies of water. The information is obtained from the internet while conducting research. Then students draw upon prior knowledge from a film to combine information for the purpose of creating a...

Students work in small groups and design a ship out of balsa wood. They hypothesize what happens when the ship is placed in water then make predictions as to which ship stays afloat the longest with the greatest amount of weight added.

Students investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.

In this water worksheet, students compare and contrast elements and compounds. Students define chemical symbols, chemical formulas, and chemical properties. This worksheet has 19 short answer questions.

In this water testing pre-lab worksheet, students describe positive ions, precipitate, and the Tyndall effect. This worksheet has 14 short answer questions.

Students investigate the factors affecting climate using Live Access Server. In this geography lesson, students graph atmospheric data using Excel spreadsheet. They compare and contrast temperature, precipitation and water vapor of two...

Young scholars 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 observe the concept of evaporation. In this evaporation lesson plan, students observe this by either charting as the sun evaporates water over time, or watching a boiling pot steam.

In this scientific method worksheet, middle schoolers test how many drops of water can fit onto a penny before it overflows and answer short answer questions about the process.

Students determine how much moisture in the air affects the diurnal temperature range. They investigate to determine the different climatological regimes of both the Southern Plains and the world. and greenhouse gases effect the earth's...

For this everyday editing learning exercise, learners correct grammatical mistakes in a short paragraph about the Greek myth of Aquarius. The errors range from capitalization, punctuation, spelling, and grammar.

Turn on water, put hands in the water, pump soap. Keep track of a learners' steps to independence with a handwashing task analysis sheet that lists nine observable behaviors that can be rated.

We can see the result of electricity  but not the process itself. The simulation compares electric circuits to a water tower and water wheel cycle. Young scientists adjust the height of the tower, the amount of resistance, and if...

Middle schoolers measure salt content in water. They determine salt content of four samples using a hydrometer.

Plant roots are the focus here. Pupils discover that some plants actually store food in their roots, that roots provide water for plants, and that gravity and sunlight have an effect on plants. This terrific, six-page plan has two...

Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

A helpful worksheet encourages pupils to make environmentally-friendly choices at home. The packet presents many ways that learners can help the environment, such as taking shorter showers in order to conserve water.

Students investigate nutrient cycling in a simplified desktop ecosystem involving aquarium and hydro-ponically grown plants. They set up an aquarium with 10 gallons of water at least a week before the lab is planned and place...

Space scientists use water displacement to determine the mass of a cubic centimeter mini meteorite, and then use it as a small-scale representative of an asteroid. They figure out the orbital velocity of an asteroid. Then they use a...
