In this activity, students are introduced to water and its three phases - solid, liquid, vapor. Students will use their senses to observe, taste, feel, and describe water, and their imaginations to understand the concepts of water's phases.

This article highlights resources related to water from the American Museum of Natural History and at-home activities on ice and water.

Students use NASA photographs and hands-on activities to compare the amounts of land and water on our planet. They discover that the world has five oceans, and that they cover 70% of Earth's surface. Students learn how this affects the entire Earth system.

Students learn about and experiment with the concept of surface tension. How can a paper clip "float" on top of water? How can a paper boat be powered by soap in water? How do water striders "walk" on top of water? Why do engineers care about surface tension? Students answer these questions as they investigate surface tension and surfactants.

This is an interesting lesson about the concept of living things. Students will be introduced to a pretend boy named C.M. Beg. The initials of the boy will be a mnemonic device to help students understand the basic characteristics of living things. C stands for change. M stands for move. B stands for breath. E stands for eat. G stands for grow.

Water is a limited resource that we use over and over again. The idea is to teach the science behind the water cycle, where water comes from and is located on the Earth. After research and developing and understanding of conservation students will create a water tower that will collect and store rainwater. Students will also create a Public Service Announcement (PSA) on water conservation.

When water utility personnel recognized their groundwater withdrawals were damaging ecosystems in the Tampa Bay area, they found new ways to reduce their dependence on it.

This article lists common misconceptions about states and changes of matter and the water cycle. It provides formative assessment probes and information about teaching for conceptual change.

This article describes six collaborative and real data projects that engage elementary students in collecting and sharing local data and communicating with students across the country and world.

This article from the free online magazine Beyond Weather and the Water Cycle provides appropriate science lessons for Grades K-5. The focus is on acquainting young learners with climate-change concepts that are not too complex for their grade level and will not frighten them. In each issue, the magazine develops articles around one of the seven essential principles of climate science. The author believes early lessons about water availability and extreme weather events will prepare students for complex climate concepts they will encounter in later grades.

In the growing season, farmers and ranchers keep a watchful eye for any sign of drought. Early warning information can increase their range of options for dealing with the lack of water.

Students will use various objects in the classroom to experiment with nonstandard measurement. They will make estimates and test them out. Then, working in pairs or small groups, students will use a ruler or a measuring tape to become familiar with how to use these tools for standard linear measurement. The purpose of this activity is to practice making standard and non-standard measurement and to learn the purpose of making linear measurements and how to apply them to scientific investigations. Students will learn how to make measurements, both nonstandard and standard (with a ruler). They will test their estimates and record their results.

In this unit, students explore the various roles of environmental engineers, including: environmental cleanup, water quality, groundwater resources, surface water and groundwater flow, water contamination, waste disposal and air pollution. Specifically, students learn about the factors that affect water quality and the conditions that enable different animals and plants to survive in their environments. Next, students learn about groundwater and how environmental engineers study groundwater to predict the distribution of surface pollution. Students also learn how water flows through the ground, what an aquifer is and what soil properties are used to predict groundwater flow. Additionally, students discover that the water they drink everyday comes from many different sources, including surface water and groundwater. They investigate possible scenarios of drinking water contamination and how contaminants can negatively affect the organisms that come in contact with them. Students learn about the three most common methods of waste disposal and how environmental engineers continue to develop technologies to dispose of trash. Lastly, students learn what causes air pollution and how to investigate the different pollutants that exist, such as toxic gases and particulate matter. Also, they investigate the technologies developed by engineers to reduce air pollution.

This article aligns the concepts of Essential Principle 2 of the Climate Sciences to the K-5 content standards of the National Science Education Standards. The author also identifies common misconceptions about heat and the greenhouse gases effect and offers resources for assessing students' understanding of interactions among components of the Earth system. This article continues the examination of the climate sciences and climate literacy on which the online magazine Beyond Weather and the Water Cycle is structured.

This article identifies age-appropriate national science education content standards and curriculum connections for introducing complex concepts contained in Principle 7 of the Essential Principles of Climate Sciences. The principle describes consequences of climate changes on Earth systems and human lives. The content standards will help teachers determine appropriate topics for their students. A number of resources from the online magazine Beyond Weather and the Water Cycle are highlighted for their connection to the science curriculum in the early grades. In addition, the article identifies common misconceptions about weather and the water cycle often held by students.

This lesson provides an overview of the major factors that affect plant growth including: water, air, temperature, light and nutrients. If sticking to the basics, the lesson can be taught using all factors except nutrients. However, nutrient information is provided for longer class periods.

This is a unit on fish habitats. The activities include the following: looking at pictures of fish and their habitat, talking about what all animals need to live, how fish live, making a poster of a fish habitat, and finally visiting a lake.

This article provides science content knowledge about forces that shape the Earth's surface: erosion by wind, water, and ice, volcanoes, earthquakes, and plate tectonics and how these forces affect Earth's polar regions.

This activity is an easy way to demonstrate the fundamental properties of polar and non-polar molecules (such as water and oil), how they interact, and the affect surfactants (such as soap) have on their interactions. Students see the behavior of oil and water when placed together, and the importance soap (a surfactant) plays in the mixing of oil and water which is why soap is used every day to clean greasy objects, such as hands and dishes. This activity is recommended for all levels of student, grades 3-12, as it can easily be scaled to meet any desired level of difficulty.

The books selected for this list complement articles in the issue of Beyond Weather and the Water Cycle that introduce the concepts of water availability and of extreme weather conditions. In nonfiction and fiction, the books for Grades K-5 emphasize that freshwater is a limited resource and explain how and why extreme weather events occur.
