Learners use microscopes to investigate the diversity of life that exists in pond water. They then conduct a controlled investigation to study the effect of a pollutant (rice) on a microcosm ecosystem.

Young scholars explore the concept of mass balance, flow rates, and equilibrium using a simple water bucket model. In this JAVA based online interactive modeling activity, they vary flow rate into the bucket, initial water level in the...

Students participate in a series of experiments to determine how acid rain contributes to the deterioration of buildings and monuments. Using common building materials, students compare the noticeable short-term affects of distilled...

Students show how constant irrigation, with repeated evaporation of water that left salts in the soil, eventually ruined much farming land in southern Mesopotamia. They discuss the idea that with the development of irrigation people...

Students discover the purpose of plant roots and how they move water through a vascular system. They conduct an experiment using colored water to observe the movement of water through the roots and stem of a plant in a controlled...

Fifth graders conduct an experiment.  In this changing matter lesson, 5th graders receive a cup of crystals, record their observations, add water to the crystals and record new observations. Students then discuss the differences...

Students experiment with liquid measurements using water. They measure liquid ingredients for punch using cups, pints, quarts, etc. and drink their efforts. They take a liquid measurement conversion quiz.

Students examine how food webs illustrate the ways in which organisms depend on each other for energy and nutrients, and make food webs showing the feeding relationships among organisms encountered in the Gal??pagos coastal waters.

Students conduct an experiment with potato cores and a sucrose solution to investigate how salt water fish process water. They develop a lab report of their experiment.

Young scholars participate in a simulation to illustrate the spread of HIV. They use phenolphthalein, water and test tubes to simulate the spread of the virus and discuss results and variables after the activity.

Students examine the benefits wetlands provide to man and nature. They compare types of wetlands in northeast or east-central Florida. They discover ways that uplands affect wetlands and water bodies.

Seventh graders, after defining/brainstorm the task, divide up into groups and are assigned to an alternative energy source (wind, solar, or water) to research. They complete a presentation with visuals on their findings from their...

Second graders construct a pond habitat in the classroom using a small swimming pool partially filled with water, real cattails, a tree log adjoining, and plastic animal life appropriate to a pond setting. They examine the frog in detail...

Students are able to describe the reproductive cycle of the gopher frog. They are able to describe the impacts of habitat loss and degradtion on gopher frog populations. Students are explained that many factors limit the survival of...

Learners use hands on scientific observation to determine characteristics of wood. They work directly with the materials and record their observations. Students test if wood absorbs water, if wood floats or sinks, and if all wood...

Fourth graders explore how the landscape of the planet can be changed by different elements of wind, water, ice and chemicals through hands-on activities. They examine pictures of areas around town and discuss anything they think is out...

Learners brainstorm what matter is and how they define it. They construct a water molecule with marshmallows and toothpicks. In addition, they watch videos to explore the use the idea of nanoscience to investigate the properties of...

Students review the Scientific Method with a hands-on activity. Working with a partner, they hypothesize the number of water drops that fit on the heads side of a penny. They collect data and share their results with the remainder of...

Students identify and interpret plant growth as well as gain graphing skills and other important knowledge related to potting plants. They take a regular milk jug and cut off the top, leaving the handle and the rest intact. Then,...

In this changes of matter worksheet, students write in what happens when water is heated and when water gets very cold. This worksheet is a graphic organizer.

Students make coffee filter eggs. In this art activity, students cut coffee filters into egg shapes. Food coloring is added to water and students drop the colors onto the eggs using a eyedropper. Students allow the filters to dry and...

Fourth graders sample the rich diversity of Canada's people and cultures, glimpse the vastness of Canada's lands and waters, and get an idea of the wealth and variety of its resources, wildlife, and history.

Students explore the volume of groundwater using math problems. They compute mathematical problems to figure the volume of groundwater and calculate the average porosity in an aquifer. Students estimate the amount of water needed to...

Students investigate different factors that affect plant growth. They research the effects of water supply, radiant energy, air temperature, and soil temperature. Students also gather facts that influence plant nutrition that include the...
