Create a simulation of acid rain in your classroom with lemon juice and bean plants to help kids study the effects of pollution on plants. In addition, learners will listen to a story and write responses based on guiding questions.

First graders access prior knowledge about pumpkins and read the story Pumpkin, Pumpkin. They will sequence the life cycle of the pumpkin through the use of picture cards and then sing a song about the life cycle of the pumpkin and plant...

Elementary schoolers study the geographic location of the Sonoran Desert. They pay close attention to the characteristics of the plants and animals found in this desert environment. The student handouts embedded in this plan are...

Young scholars engage in a lesson which explores the wate cycle. They get to see some very entertaining video, do fun hands-on activities and gain a better understanding of evaporation, condensation, precipitation and collection.

Students create a diagram that traces the path of a raindrop from its source into the water supply for their house and back to the environment. They also diagram the processes that occur in a sewage treatment and water treatment plant.

The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

Learners explore water and ice. In this physical science lesson, students participate in a science inquiry and observe the characteristics of ice and water. Learners compare the differences between a solid and liquid and record their...

Students discover the forms water can take. In this hands-on science lesson, students examine how water can change from a solid to a liquid and then back again.

Students investigate how water goes from a solid to a liquid then back again.  In this experimental lesson students conduct their own experiment and see how water changes form. 

Geology beginners examine three different rock samples and determine their origin by their characteristics. By making and recording observations, they become familiar with features of igneous, metamorphic, and sedimentary rock types....

Hydrology hopefuls learn about their local watershed. Through discussion and online interactives, they see that their habits affect the water supply. The lesson concludes with a pledge to filter out bad water usage habits. It makes a...

It's raining, it's pouring! Simulate the precipitation process with rope or hula hoop and assorted colored construction paper. This simple game should give young learners a better understanding of how rain falls.

Learners complete a KWL chart on what they comprehend about water. They complete a water activity determining how much usable water is available, and they determine the water usage in their households. Students take notes on water and...

Students explore cycles in nature. In this cross curriculum agriculture lesson, students define "cycle" and research weather and planting folklore. Students make a bracelet in which individual colored beads represent the many "cycles" of...

Learners explore how various substances change from a solid to a liquid or from a liquid to a solid and how temperature, pressure and nature play an important role in this process. In this melting and freezing...

Second graders explore weathering and how the water cycle plays a part in weathering. In this weathering lesson plan, 2nd graders put gravel and sugar cubes in a jar and shake, simulating weathering. Students use the scientific...

Greenhouse gases affect marine wildlife in life-threatening ways. Through experimentation, your classes explore the acidification of water from the main greenhouse gas carbon dioxide. As they introduce carbon dioxide to water, a pH...

Fifth graders examine the stages of the continuous water cycle that exists on Earth. They observe a water cycle model that is set up in the classroom and write descriptions of what they see. As a class, they discuss models of the water...

Students explore the traits of water condensation and evaporation. In this water cycle lesson, students develop an awareness of the importance of water for sustaining life. Students participate in a hands-on activity in which water is...

In this rock cycle worksheet, students use different colored crayons to represent different types of rocks. They follow step by step procedures to model the rock cycle with the crayons. Students draw the rock cycle, show weathering,...

Third graders conduct an experiment to determine how water moves through different soils found in the Apalachicola River watershed. They read a scenario, conduct the experiment, answer follow-up questions, and draw the water movement...

Students discuss ammonia, and ways it may get into the aquarium. They complete a worksheet about the Nitrogen Cycle. Students learn how to get the ammonia and nitrite out of their aquarium.
