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...

Students 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, high schoolers 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...

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...

Young scholars 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...

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 learning exercise, students compare and contrast elements and compounds. Students define chemical symbols, chemical formulas, and chemical properties. This learning exercise has 19 short answer questions.

In this water testing pre-lab worksheet, learners 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...

Pupils 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.

For this scientific method worksheet, students 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...

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

Get into springtime with a festive practice sheet designed to test scholars' knowledge of grids. Learners locate items such as watering cans, snails, and flowers following the x and y-axis. Worksheet themes include Earth Day, gardening,...

A dripping faucet may be enough to drive you crazy, but it also teaches you a little about ratios. Presented with the volume of a sink and the rate the water is dripping, scholars must devise a plant to determine how long it will take...

Soften up an egg. Learners use vinegar to test for calcium carbonate in an egg shell and an antacid tablet and compare the reaction with vinegar to the reaction with water. In a second experiment, class members break down an egg shell...

Heat up a lesson on solar energy. The first of three parts in the Experimenting with Solar Heaters unit has scholars construct solar heaters. They then use them to heat up a container of water and calculate the amount of heat energy...

If changing one variable can improve a design, why not try changing more? Using the results from the previous activity, scholars decide on the variables that caused the most improvement in the effectiveness of the solar heater. They take...
