Students experiment to discover how different variables affect the water cycle. They do hat flow experiments and construct a computer heat flow model.

Learners participate in a hands-on activity that demonstrates how the water cycle functions. Students look specifically at condensation and evaporation during the recycling of water.

Explore soil, genetic traits, natural resources, and pollution in a series of lessons that focus on biodiversity. Kids complete experiments to learn more about the importance of varied genes and organisms in an ecosystem.

Scientists use ice core samples to obtain temperatures of the earth from 400,000 years ago! The third of five lessons instructs pupils to interpret historical climate data to see changes over time. In part I, participants interpret...

After a reading of Lois Ehlert's Planting a Rainbow, class members plan a rainbow garden, research growing cycles of the fruits and vegetables in their section, and then plant and maintain the garden.

Photosynthesis seems nothing short of magic: a little carbon dioxide and water, add energy, and poof, you get food! A thorough, collaborative lesson teaches youth the process of photosynthesis thanks to a skit they perform with a group...

In this water worksheet, learners answer 10 multiple-choice questions about the water cycle. Students also describe how they think their community is involved in sustaining water resources and write a pretend radio announcement about...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Students use Inspiration to map cyclical events. They recognize links between separate events and structural patterns. They explore the Internet Connection section to browse additional resources on teaching about cycles used in...

Students state the physical, chemical or biological processes associated with these environments: Pelagic ocean zone, California coat Cave, Indiana Barrier island beach, North Carolina Sand dune, Dunes National Park, Colorado Wetland and...

Students model a watershed and delineate one using topographic maps. In this hydrology instructional activity, students use aluminum foil to model a landscape and observe how water moves on it. They also observe the features of a...

Students identify the stages of the salmon life cycle. In this fish instructional activity, students experience first hand what it would be like to be a returning salmon attempting to identify a home stream by smell.

Students apply cause and effect relationships to water pollution in a stream. In this pollution lesson students recognize the importance of clean water in their daily lives. Students accompany "Fred the Fish" as he travels down stream....

Middle schoolers demonstrate how water flows by building a human watershed using themselves. In this ecology lesson, students compare and contrast point-source and non-point source pollution. They write what they have learned from this...

Learners investigate about cycles through games, shared readings and a shared writing activity. They play a game of Ring Around the Rosie to be introduced to the concept of "cycle."

Students develop an understanding and appreciation of water purification techniques and their implications for health maintenance.

In this where water goes quiz worksheet, students complete an on-line quiz, clicking on questions and matching answers, scoring 1 point for each correct answer. A printed version is available.

A video and laboratory investigation are highlights to this lesson on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...

As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...

Quite a detailed and advanced look at the transport mechanisms of a plant. The absorption and control of sugar and water concentration are explained and will help an understanding of homeostasis concepts and organ specialization.

Give young geologists an up close and personal look at volcanoes with a series of hands-on earth science lessons. Whether they are investigating the properties of igneous rocks, building their own volcanoes, or making...

Students explore decomposition and soil health by creating their own garden.  In this agriculture lesson, students build a "lasagna garden" with organic matter found in the area and plant perennials native to their region....

There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...
