The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

Getting water to a tap requires an understanding the fundamentals of fluid flow. Groups design, build, and test a piping system to get water from the source — a five gallon bucket — to a tippy tap. The objective is to be able to...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Combat ocean acidification with bubbles. Young engineers create a system that reduces the acidity of water. Dry ice in water helps simulate ocean acidity, and blowing bubbles into the water results in a gas exchange that neutralizes the...

What a bright idea! Young scientists conduct an experiment on flowers to finish the last of a six-lesson unit on Cells. Putting the stems into dye-injected water and leaving it overnight results in flowers that glow. This is to simulate...

What is water worth to you? The answer probably depends on many different variables. Learners explore the value of water in space and what it takes to transport the resource to locations in a galaxy far far away. They then consider...

Three days of erosion exploration await your elementary geologists. Learners begin by examining rivers via Google Earth, then they model water flow in sand, and finally, they identify resulting landforms. This lesson is written...

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

What's in a cell, anyway? Kids read informational text on what makes up both animal and plant cells, including a page of vocabulary terms they will need to be familiar with (cytoplasm, ribosomes, vacuoles, etc.). Full-color images...

Energize the cells of young biologists with an edible life science activity. Engaging students in exploring the inner workings of plant and animal cells, this activity involves using colored jello and various sweet and...

Don't desert a resource on the desert! Scholars work in groups to build on their ideas from the previous lesson to design a sustainable guest village in the Saguaro National Park. Each group produces a PowerPoint presentation to share...

You've probably heard of solar-powered cars, but what about wind-powered cars? Scholars build cars that can travel at least six feet. They can only use their breath to move the car—so, obviously, a sail might be a good feature for the...

Middle schoolers work as a team to help improve the quality of life in rural Africa and develop a plan how to spend grant money the United Nations has provided them with.

Students read about old telephone books are being recycled to make new objects and then answer short answer questions about it. In this recycling lesson plan, students also look into their books to find information.

Challenge your students to create a satellite that can hold a cup of water and does not leak during a bumpy rocket launch. This site comes complete with a challenge, tips, a lesson plan, and a place for students to document their...

Resource provides an explanation of Cell Transport. Includes many practical examples, as well as pictures. Sections include Water and Solute Movement, The Cell Membrane. Cells and Diffusion, Active and Passive Transport, Carrier-assisted...

Engineers work in many fields associated with precipitation. Engineers study glaciers to better understand their dates of formation and current demise. They deal with issues of pollution transport and water yield, and they monitor...

This hands-on activity explores five different forms of erosion (chemical, water, wind, glacier and temperature). Students rotate through stations and model each type of erosion on rocks, soils and minerals. The students record their...

The Tippy Tap hand-washing station is an inexpensive and effective device used extensively in the developing world. One shortcoming of the homemade device is that it must be manually refilled with water and therefore is of limited use in...

In this activity, students work with specified materials to create aqueduct components that will transport 2 liters of water across a short distance in their classroom. The goal is to build an aqueduct that will supply Aqueductis, a...

In a class demonstration, students observe a simple water cycle model to better understand its role in pollutant transport. This activity shows one way in which pollution is affected by the water cycle; it simulates a point source of...

In an open-ended design activity, students use everyday materials (milk cartons, water bottles, pencils, straws, candy) to build a small-scale transportation device. They incorporate the use of a wheel and axle, and lever into their...

AtoZteacherstuff.com presents "Identifying Erosion", a lesson plan for grade levels 3-5. Related URLS and teacher feedback provided.

Student teams learn about engineering design of green fluorescent proteins (GFPs) and their use in medical research, including stem cell research. They simulate the use of GFPs by adding fluorescent dye to water and letting a flower or...
