Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

How much plastic do manufacturers use to create water bottles each year? The class explores the number of water bottles used throughout the years to determine how many consumers will use in the future. Class members compare different...

Young scientists explore Earth elements by conducting an experiment. They define water vocabulary terms such as condensation and precipitation. In addition, they conduct a water experiment in which they build a terrarium, so they can...

Students measure the amount of surface tension using a balance scale after a classroom demonstration students diagram the appearance of several liquids and label them.

Students study the amount of potable water on the Earth. In this water lesson, students examine the amount of potable water as compared to all the water on the Earth. They discuss why many parts of the world do not have access to good...

Students examine and calculate the percentage of potable water remaining on the earth. In this ecology and geography lesson, students brainstorm the main factors affecting water distribution. Students use mathematical problem solving to...

Students explore and examine the increases and/or decreases for water user groups: irrigation, municipal, manufacturing, steam electric power generation cooling, livestock, and mining. They utilize percentage changes during their...

Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...

Thirsty plants soak up every bit of a rainfall, but what happens to the rain that hits the roof? Calculate the amount of rainwater from your school's roof with an Earth science activity, which brings measurement skills, observation...

Students determine a watering schedule that promotes healthy grass growth. For this plants and natural resource conservation lesson, students plant grass seed in liter bottles and follow two different schedules that include "more...

Students complete experiments to determine how rocket fuel is affected by surface area and temperature. They compare the reaction rates of antacid tablets. They discuss their results to complete the lesson.

Learners explore the differences between surface water and ground water. They collect data using maps and graphs and investigate a Texas river basin and a nearby aquifer. They complete a written report including maps and data regarding...

  Learners observe a leaf and discuss the way that water is released from a leaf through its stomata.  For this water cycle lesson, students calculate how much water leaves produce from a whole tree.     

Learners construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas - produced from a chemical reaction between an antacid tablet and water -...

Finding a balance between too much protein and not enough doesn't have to be a guessing game. Young scientists use an interactive lesson to learn how to calculate protein content in cattle feed and how to mix feed to create the ideal...

In this rain forest worksheet, students use different basic math skills to calculate the percentage of Earth covered by rain forests today compared to fifty years ago. They study the effects of how cutting down trees contributes to water...

Learners construct paper. In this applied Science activity, students create paper using lint. Learners investigate the different fibers in their homes.

Students study the water quality of a stream in their area, by measuring the temperature, pH, alkalinity and conductivity. They integrate biology with earth science when using the microscope to study the living organisms in the water.

Students set up their own monitoring system. They collect samples from an appropriate sampling site. They analyze data and determine the water quality. They present their information to the class and draw a conclusion.

Water, water, everywhere? Each pupil first uses an Internet program to select 50 random points on Earth to determine the proportion of its surface covered with water. The class then combines data to determine a more accurate estimate.

Learners are designing a stunning new water feature for an aquarium, but they soon discover that more than just a pretty home for their fishy friends is required.  From calculating the volume of a composite shape through the...

Students, after researching a Texas coastal basin, map and graph the information they collect and then translate it into a short report to be presented to their classmates. They brainstorm unique ways to maintain Texas estuaries as well...

For this ocean worksheet, students are given a map of the world and they predict the amount of water that covers the Earth's surface. They count the total number of squares on the given map that represent the water and they land and they...
