Students 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.

Students investigate the properties of matter. In this properties of matter lesson, students observe containers of different metals and discuss their properties including density. Students find the density of an unknown metal and of...

In this water desalinization worksheet, students will design and construct their own desalinization plant. Then they will describe how they set up their experiment and if it worked or not.

Students conduct experiment with water striders by placing the insect in two different solutions and discuss their observations. They discover that weight and surface area are important factors in their experiment.

Students explore the unique behaviors of water. They investigate surface tension using water drops on a penny and pennies dropped in a cup.

Can scientists sort molecules based on their interaction with oil and water? The simulation demonstrates how this is possible. Pupils decide when to insert a molecule and observe how they sort themselves based on polarity.

Instill the concept of adaptation with the help of Blubber Gloves—ziplock bags, shortening, and duct tape. Scholars discuss how animals and plants keep warm in polar regions, record their predictions, and try on their Blubber Gloves to...

In this mixtures worksheet, students read about mixture and what determines if a solute dissolves in a solvent. They answer three questions about solutions and determine from a list of compounds which are soluble in water.

Third graders are introduced to the topic of habitat . They create a zoo exhibit fo a polar bear that is being donated to the Albuquerque Zoo. The zoo is not big enough for a brand new cage, so the students choose which of three...

Students make a model of a polar bear and discuss why fur/skin color is important. They also perform a simple experiment using black and white socks to determine how color affects temperature.

This is not they typical set of teacher instructions. It is an organized chart of the important organic compounds. For each, the involved elements, the name of the building block monomers, the names of polymers, extra information, and a...

Ninth graders examine the electrolysis of water by completing an experiment.  In this water lesson students will explain how hydrogen can be extracted from water and how energy flows through an electrolysis system. 

Illuminated physics stars show what they know about light by taking this exam. They match several related vocabulary terms to descriptions and answer multiple choice questions about the characteristics of light, magnification, and...

Students investigate adhesion, cohesion and surface tension. In this molecular forces lesson plan, students observe multiple demonstrations that show surface tension, the attraction of water molecules to each other and the ability of...

In this solutions worksheet, learners review the properties of solutions, the polarity of molecules, molarity, and solubility curves. This worksheet has 8 short answer questions and 15 problems to solve.

Young scholars get a first hand look at the benefit of a "blubber layer" in cold climates through a simulation using vegetable shortening and icy water. Through this simulation, students examine how adaptations help organisms survive.

In this solutions, suspensions and colloids instructional activity, students use diagrams to show how particles are different in each of these mixtures. They also distinguish between characteristics of each of these types of mixtures and...

Let there be light! When your physics learners take this midterm exam, light will be their focus. They will show what they know about electromagnetic waves, interference, refraction, reflection, lenses, prisms, and more! The test is...

In this covalent compounds worksheet, students name 6 compounds given their chemical formulas, they write the formulas for 6 compounds given their chemical names and they answer questions about boiling points and solubility. They write...

Students chill out on a hot day with this outdoor activity. In this early childhood physical education lesson, students have fun experimenting through play with ice and toy animals in water.

Explain the properties of water. Identify the properties of water that make it a polar molecule Describe hydrogen bonds and how they differ from covalent bonds Discuss the differences between hard water and soft water Compare the heat of...

Students examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.

Provide a review for the exam so individuals don't tank. AP® provides the free-response questions for teachers to use to help their pupils prepare for the exam. The six BC questions from 2007 include regions bounded by functions, water...

Students observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water
