Pique interest in water pressure, demonstrate buoyancy, and explore water displacement concepts with a homemade Cartesian diver. You may want to change the name of the toy, however, as is is not documented the Rene Descartes...

Guide your learners through the water cycle with this lesson plan. Over the course of the instructional activity, they read two Magic School Bus books, discuss the water cycle, come up with water facts, complete a diagram of the water...

Students spend time examining the concept of water pressure. In groups, they research the amount of air pressure that is felt at different levels above sea level. Using a calculator, they calculate the water pressure given different...

Pupils participate in a role play where they play clouds, the ocean, rain drops, and more in order to learn about the water cycle. In this water cycle lesson plan, students have discussions and learn vocabulary.

Learners examine the disparity of resources between developing and industrialized nations, and research the problem of water availability as world populations increase and natural resources are stressed.

Ninth graders conduct research on the subject of sea water. They use a variety of resources to obtain information. There are helpful resource links listed in the lesson. In conjunction with the research students make inquiry of the...

Put the pressure on as your class endeavors to construct an indestructible submersible! By watching a video, participating in class discussions, and the applying the complete scientific process, learners design a capsule that is slightly...

Students observe and discuss what happens when water turns to ice and when ice turns into water. In this freezing and melting lesson plan, students observe ice and water and complete hands on activities that change their properties.

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 explore the water cycle. In this earth science lesson, students observe and measure water in a closed container and in an open container. Students record their observations and compare their sets of data to draw conclusions...

How can you launch an object that isn't propelled by air? The resource provides directions to build a launcher to launch rockets made of two-liter bottles. The launcher, built mainly from materials found at the local hardware...

Learners decide whether or not there is or has even been water on Mars. They analyze temperature and pressure data from the Pathfinder mission to Mars, and then they analyze images of Mars, interpreting the landforms they see and...

Although it requires a little extra preparation the first time you use this geyser demonstration, it can be used repeatedly once it has been constructed. This demonstration is useful in showcasing how heat leads to increased pressure and...

Here is an attractive learning exercise that walks chemistry learners through a review of aqueous solutions. There are matching, short answer, and multiple choice questions dealing with boiling and freezing points, precipitate, molality,...

This presentation is about air. What makes it unique is that, in addition to simply providing information about the components of air and the action of air pressure, it  includes a series of four experiments that bring these...

Learners investigate water column data. In this earth science and seawater instructional activity, students determine how temperature, salinity, and density have an impact on sea water by viewing and analyzing data obtained from a number...

Students predict what happens to the balloon as the water in the flask boils. In this physics lesson, students explain why they made such prediction. After the demo, they give some real life examples of this concept.

Why are the properties of the water important when exploring the ocean? Young scientists discover the tools and technology used in deep sea exploration in the fourth installment in a five-part series. Groups work together to...

How much water does your body lose during exercise? How much should you hydrate during and after exercise? Address the importance of hydration with your young athletes using this informative handout.

Students complete an experiment in which they demonstrate that air exerts a force. In groups, they create their own siphon and define air pressure. They estimate the time it might take to siphon various amounts of water. They collect,...

Middle schoolers are introduced to the basic principles of atmospheric pressure. After watching demonstrations, they discover the capability of air pressure and how it affects weather. In groups, they use an inquiry template to solve...

Students list reasons why water is important and investigate and graph the freezing points of different solutions.

Middle schoolers investigate water vapor. They view and analyze photos, conduct Internet research, and analyze the total water vapor/total liquid water data plot.

To reinforce the action of air pressure, have your meteorology pupils construct a barometer. They place the barometer into a closed system, a miniature atmosphere if you will, and notice the movement of the needle on the homemade...
