The four cycles in Earth's biogeochemical system are covered in this worksheet. Science stars fill in the blanks or define vocabulary terms pertaining to the hydrologic, carbon, nitrogen, and phosphorous cycles. This resource provides a...

The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...

In this ESL/EFL comprehension worksheet, learners read or listen to an article entitled, "Water Supply returns to Chinese City." They participate in discussion activities, and written exercises. They complete fill in the blank, true or...

Students investigate pH levels in bodies of water and experiment with acid/base reactions. In this water and pH lesson, students observe changes in pH levels of a sample solution and observe a Bronsted-Lowry reaction. Students...

Using a colorful infographic handout and a guide sheet, hold a class discussion about how a bathtub can serve as a model for the greenhouse effect created by Earth's atmosphere. Participants will understand that as energy or matter is...

Young scholars research the water cycle and identify main vocabulary associated with the water cycle. They build and observe a closed system model that demonstrates the water cycle in action.

Students discuss the different types of water found on Earth. They discover why not all water is used for drinking and calculate how much water they use. They create their own water conservation plan.

Students differentiate between how they use water in response to a need and how they use water for pleasure. They read books about water, participate in class discussion and illustrate their observations.

Young scholars discover the amount of water used for everyday activities around their home in this lesson. They research the amount of water needed by accessing a provided internet link. They then graph the information they discovered...

Seven pages of fascinating reading on marine debris preface the activities in this lesson plan. Four different activities are employed to simulate how the debris is distributed in the ocean and along beaches. Early ecology learners...

Young scholars conduct a number of experiments involving evaporation and condensation. They view and discuss a video about the water cycle and then design posters about the rain based on the book "Cloudy With A Chance of Meatballs".

Students explain the processes involved in the cleansing and purifying of surface water. After a lecture/demo, students engage in an experiment that illustrates how water is cleansed before we drink it.

Seventh graders discuss water quality, water availability and water resources and how water is used in the world around them. They view a video on water quality then test for pH, temperature and dissolved oxygen to indicate water quality.

Pupils explore potential issues of a water shortage.  In this water conservation lesson, students brainstorm the many uses of water and what life would be like if there was not enough water available.

In this unit of lessons, students examine water quality issues. They discover ways they can conserve water and practice making drinkable water from water desalination.

Third graders observe various demonstrations dealing with the water on our earth, such as a comparison of the amount of salt water and fresh water on earth, then participate in a role playing activity in which they become a molecule of...

Students work together to examine the role of water in their lives. They discover the process to clean water so it is clean for one to drink. They explore the role of environmental engineers and their problem of getting clean water to...

Middle schoolers complete an online quiz about their familiarity with water issues. As a class, they watch a demonstration by their teacher and work together in groups to make water change into its various states. To end the activity,...

Young scholars design an experiment to determine which liquid is water. In this chemistry lesson, students perform the experiment as outlined in their design. They record observation and formulate conclusion.

Young scholars comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and...

Students create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...

The size of a nanoparticle is difficult for pupils to grasp. A hands-on experiment is designed to give your classes perspective. Learners analyze different sports drinks for the content of electrolytes as an introduction to nanoscale....

Why do we sweat? Scholars analyze data about body temperature, sweating, and other factors to better understand sweating. They note the changes after drinking ice water to sweating, skin temperature, and body temperature. Analysis...

Earthquakes are really no one's fault. A thorough lesson explains the different types of earthquakes how they happen. Learners interact with the online lesson to simulate earthquakes and examine their results. The lesson is appropriate...
