An inventive and interesting lesson plan on the water cycle (and other cycles associated with it), is here for you. After doing a well-designed hands-on inquiry in class, learners also identify organisms and processes that are involved...

Looking for a tree-rific addition to your water cycle unit? Teams of young foresters examine the role of transpiration in the water cycle through a week's worth of activities. Pupils analyze how trees take in and transport water during...

Students explore the water cycle. In this water cycle lesson, students examine water as a resource as they create a water cycle poster and create a water cycle model. Water cycle game instructions are included as well.

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

Students explore the relationship between the amount of water in the atmosphere available for precipitation and the actual precipitation observed by satellite. They examine seasonal changes in precipitation. They practice using Internet...

The goal of this science lesson is to have youngsters be able to identify the physical and chemical changes in the carbon cycle, and water cycle due to weathering. The in-class inquiry/experiment is quite interesting and easy to...

A thorough background and nitrate sampling lab sheet are provided to share with your young scientists. After discussing the nitrogen cycle with the class, you will break them into small groups and show them how to use their inquiry...

The evaporation of water and what happens to it as it travels through the water cycle are the focuses of this instructional activity. The evaporation of water seems like a "magical" process to people of all ages. This instructional...

Third graders create a KWL chart about water. For this environmental science lesson, 3rd graders demonstrate how much water on Earth is usable. They act out the different stages of the water cycle.

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

Students participate in an experiment about evaporation. In this water cycle lesson, students use water, thermometers, and measuring tools to make a puddle and measure the size four times throughout the day. Students discuss their data...

Second graders participate in a three part lesson in which they identify and describe forms of moisture in the environment. Part one of the lesson involves the three stages of the water cycle, part two focuses on creating humidity by...

Students explore the properties of water and how it changes states. In this kindergarten to 2nd grade science lesson, students pair a hands-on science activity with two suggested books. This inquiry lesson has...

Students explore reasons for varied salinity in bodies of water. In this geographical inquiry lesson, students use a variety of visual and written information including maps, data tables, and graphs, to form a hypothesis as to why the...

Third graders complete a KWL chart on what they already know about water and what they want to know. As a class, they participate in an activity in which they discover the amount of drinkable water on Earth and are introduced to the...

Students 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 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...

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....

Here is a simple inquiry experiment designed to demonstrate that the energy from sunlight can evaporate water. Young scientists follow provided procedural steps to construct a model of our atmosphere using a bowl, a cup, water and...

Students perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson, students use their senses and inquiry tools to understand the changes in state of water. Suggested...

Students 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 perform several water quality tests on groundwater from their area. They use test strips to determine the pH, hardness, alkalinity, nitrates, iron and chloride levels.

Students examine the rock cycle and the path that rocks go through to rearranged in different ways. They define key vocabulary terms, then in small groups conduct a variety of experiments using crayon shavings as simulated rocks and...

Young scholars use the Internet to research current and past snowpack levels and river gauging station readings. They determine the relationship between snowpack and river flow. They predict future river flow.
