Students explore physical sciences by conducting a water properties experiment. In this water pressure lesson, students utilize an empty soda bottle, water jug, water and knife to create a mock water fountain. Students create a water fountain by poking holes in precise locations while discussing the force and pressure associated with the device.
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 ATM levels and research how to deal with the effects of water pressure while examining the ocean floor.
Students compare the pressure of water at different depths and gain an understanding of how increased water might affect animals living in deeper waters. They participate in an experiment to show that depth, not volume, affects water pressure.
Students explore water pressure.  In this physics liquid pressure instructional activity, students perform several experiments in which they determine and explain what happens when pressure of a liquid is not the same on all sides of a submerged object.
Third graders complete an experiment to introduce them to the concept of water pressure. In this water pressure lesson plan, 3rd graders create pressure in a water bottle and observe the force of water that is created.
Learners discover that there is more water pressure on the bottom of the ocean than at the top. They examine how the high pressures of the deep ocean may affect the types of plants and animals that can grow there.
Play "Would You Rather" with your physical science class as an anticipatory set. Each game question is related to the pressure put on an area of the body. Let this activate a discussion on forces, pressure, and area. Give your class Newton's second law of motion and the formula F=ma. With the concept in mind, your class will explore pressure using a variety of hands-on materials. Finally, they apply their learning to the real-world scenario of deep-sea diving. A video about James Cameron's ocean exploration, handouts, detailed teacher's notes and background information, and a link to an online mapmaking activity combine for a richly detailed lesson! 
Begin by discussing pressure and showing a video clip of James Cameron's record-setting deep-sea dive. Then assign lab groups to explore how depth affects pressure and to construct a manometer. There is another video to follow the hands-on activities and a model-making project to conclude. This thoroughly-planned lesson will take your physical oceanography class to new depths!
Students identify characteristics of water. They describe the process by which light decreases and pressure increases as water depth increases. They demonstrate the principle of water pressure in a small group experiment.
Students examine air pressure. In this air pressure lesson, students perform a series of experiments to evaluate the effects of air pressure.
Students demonstrate the pushing power, or pressure, of air by completing six short experimental activities.
Students investigate barometric pressure.  In this weather lesson, students participate in several hands-on activities to show air has pressure. Students lift a textbook without using their hands, observe a demonstration where a napkin in a glass stays dry when submersed in water, and create their own barometer.
Young scholars explore geography by conducting an in-class experiment. In this deep sea exploration lesson plan, students identify the different zones of the ocean and utilize water bottles, masking tape and scissors to conduct a water pressure experiment in class which simulates deep sea diving. Young scholars define a list of oceanography vocabulary terms in class.
Students view a video clip on dams. They discuss how the dam is reinforced and how it holds the pressure of water. They participate in an activity in which they use liter bottles to represent the dam.
Students discover that air is a real substance and its' properties, through teacher demonstration and learning stations. In this physical science lesson, students explore the properties of air through the use of various learning stations. Students are able to understand the answer to why air has pressure.
First graders describe the properties of air. They conclude that air is a gas, that air has weight, that air exerts pressure and that moving air is called wind.
Young geometers apply their knowledge of volume of spheres to tackle this real-world problem about the unique water storage tank located on the campus of Montgomery College in Germantown, Maryland. After reading a published article about the tank, pupils use their skills to solve three problems presented as task questions. The activity includes good facilitator notes.
Students perform experiments measuring water pressure. They record their observations after poking holes in plastic bottles filled with water with the lids on and then off. They discover the role gravity plays in the water flow.
Fourth graders engage in a lesson which explains the differences in the three confusing terms used to describe pressure and their measurement. After a lecture/demo, 4th graders complete a worksheet imbedded in this lesson plan.
Students observe what happens when the pressure of a liquid is not distributed evenly on an object.  In liquid pressure lesson students view a demonstration and see how the pressure of a liquid works.
