Water Filtration
As an example of nature's water filtering system, young ecologists conduct an experiment in the lab. They construct a funnel out of a plastic bottle, fill it with specified layers of materials that simulate layers of soil, then run muddy...
Curated OER
Water and Ice
Students participate in various air experiments to understand that air is all around us. In this states of matter lesson, students focus on the role of air in the water cycle. Students understand that air is densest near the ground....
Curated OER
Water Pressure in the Ocean
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...

Physical Changes and the Water Cycle - Three
Third graders observe and reproduce the water cycle in their very own classroom. A simple, yet very effective, demonstration on how water evaporates is observed by the young scientists. They make observations and sketches in their...

Environmental Concerns (1) Analysis of Lead in Paint (2) Analysis of Water
A scenario and background information are provided for two different open-ended experiments that experienced chemistry classes can perform toward the end of the school year. In the first, they design a method for testing flakes of paint...

How Many Drops of Water Can Fit on a Penny?
Using a simple method, learners explore gravity, cohesion, and adhesion. They perform an experiment in which they determine how many drops of water can fit on a penny. Afterwards, they discuss their results.

Settling The Wasterwater Problem
High schoolers name models that are representations of larger objects. They suggest ways that industry, agriculture, and mining affect water quality. Pupils demonstrate the use of lagoons for treating wastewater. Students define the...

Heating and Cooling of the Earth's Surface
Scholars collect data from heating sand and water before forming testable hypotheses about why sand heats up faster. Afterward, they develop and run experiments to test their hypotheses.

Unit 3: Scientific Writing
Write-on! Demonstrate a writing model and support learners as they write an informational essay on a water resource issue of your (or their) choosing. The lesson plan provides a well-scaffolded summative writing...
Curated OER
It's Raining, It's Pouring: The Water Cycle
Learners investigate the relationship of the steps in the water cycle, and create a simulation of the water cycle in a jar.
Curated OER
Making a Surface Coating
Students prepare a nonaqueous surface coating by first making a polymeric resin and then adding an organic solvent. There product is a basic varnish that hardens by loss of organic solvent to the air. Students make a simple paint by...

Earth's Water
If the majority of our planet is covered with water, why do we need to bother conserving it? With a thorough and varied investigation into the location and types of water on the earth, learners will gain an understanding of why this...
Curated OER
Water in the Atmosphere
A slide show serves as the backdrop for a lesson on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make observations and...
Curated OER
Life on the Surface of the Earth
Students discover that life occurs on or near the surface of the Earth in land, air, and water. They read the literature selection, 'Whose Forest Is It?'
and discuss with students that there are examples of of many living things
that...
Curated OER
Water Resources
Students explore the differences between surface water and ground water. They collect data using maps and graphs and investigate a Texas river basin and a nearby aquifer. They complete a written report of their findings regarding the...

Surface Tension Basics
Back to the basics (of surface tension). The first installment of a nine-part series teaches young scholars about the basics of surface tension and how it relates to water droplets. They also learn how this concept allows for the...

Surface Tension Lab
What constitutes a good soap bubble? In the second installment of a nine-part series, scholars apply their understanding of surface tension to soap bubbles. They experiment to determine the best solutions to use for the...

Aerogels in Action
Model an oil spill cleanup. An engaging engineering lesson has groups using aerogels to simulate an oil spill cleanup (vegetable oil in water). Along the way, they learn about nanotechnology and hydrophilia/hydrophobia.

The Liquid State
Due to surface tension, dew — a liquid, is spherical in shape. Learners explore the properties of liquids in activity seven in this series of 36. Beginning with its basic properties such as boiling point and moving through to surface...

Please Pass the Salt
Salinity is the focus of two experimenters that work to answer the question, How does salt change the physical properties of water? Super scientists compare the freezing rate of salt and fresh water, combine the two waters to...

Can We Absorb Nanoparticle Pollutants?
Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

Constructing an Aquifer
Rainwater doesn't stay where it falls. Learners use modeling to demonstrate how rainwater disperses once it hits the ground. The activity includes an investigation of the height of the water table in an aquifer and how it is affected by...

Is There Water on Mars?
Students 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...
