Students study the effects of water, salt water and heat on common household materials. They separate an emulsion and show that the materials are completely recoverable and observe the effect of acetone and water on polystyrene.

Students investigate the force of gravity and how it effects different objects that are put into acceleration when applied the experiment of free falling. They drop different objects that have a variety of masses and some that cause air...

Fifth graders observe how water changes phase through a teacher-led demo. In this earth science lesson, 5th graders relate the demo to the water cycle. They draw and label each stage of the cycle.

In this chemical equations activity, students calculate how many grams are used to in the equation written as well as the grams formed in the chemical equation. Students identify the limiting reagent in some of the chemical equations....

Students investigate population dynamics such as variation in density of females, composition of food sources an environmental factors such as light and temperature on Drosophila. They then relate their findings to human populations and...

High schoolers experiment with Drosophila to determine if density of female flies, food sources, temperature and light affect the population dynamics of growth. Students graph their data and compare their results to the number of human...

Fourth graders research soil layers and create a soil profile in a jar.  In this soil profile activity, 4th graders working in groups, research a given layer of soil, make a 3-5 minute presentation to the class, and complete a...

Learners develop abilities necessary to do scientific inquiry. They develop an understanding of chemical reactions, structures and properties of matter. They develop decision-making skills in natural and human-induced hazards.

Students examine the rock cycle and the path that rocks go through to rearranged in different ways. They define key vocabulary terms, then in small groups conduct a variety of experiments using crayon shavings as simulated rocks and...

Students research a NASA Website and record information about an assigned city's tropospheric ozone residual monthly climate. In groups, they graph the information for the past year. They form new groups and compare their city's...

Students examine the organic and inorganic components of soil. In this environmental science lesson, students identify the factors that influence soil formation. They collect soil samples, conduct tests, and analyze the results.

Learners identify the cause of indoor air pollution. In this indoor air pollution lesson, students list, group, and label sources of indoor pollution. They brainstorm a list of all of the indoor pollutants they can think of before...

Students explore the layers of earth's atmosphere and conduct an experiment to identify carbon dioxide. They construct models using styrofoam to represent molecules in the atmosphere's layers. To discover how sunlight efffects...

Tenth graders investigate the carbon monoxide level at a fixed latitude to determine if there is a relationship to population density. They download data sets and generate a graph, and find locations using the Earth's coordinate system....

Pupils build an understanding of the dynamics and composition of the atmosphere and its local and global processes influencing climate and air quality. They analyze air masses and the life cycle of weather systems.

Students are introduced to the concept of surface tension, its dependence on material composition, and how it can produce uniquely shaped surfaces.

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...

Students practice their vocabulary skills. In this vocabulary skills lesson, students recall vocabulary words regarding indoor air quality.

Students build an understanding of the dynamics and composition of the atmosphere and its local and global processes influencing climate and air quality. They analyze global atmospheric changes including changes in CO2, CH4, and...

Pupils uncover the nature of volcanoes and locate some of the world's active, dormant, and extinct volcanoes. They also discover how scientists detect, measure, and predict volcanic activity.

A review of a full unit on energy and matter, this slide show starts with basic definitions of states of matter and their mass. It then develops the ideas of the forces that that matter can exert. Details about bonding within matter and...

Students organize and analyze data regarding changes in tropospheric ozone and then hypothesize about the consequences of these changes.

For this electrolytes worksheet, students calculate percent composition, determine the electrical conduction of electrolytes, and explain the Tyndall effect. This worksheet has 7 problems to solve.

First graders are introduced to the topic of researching by the librarian. Using a worksheet, they use various sources in the library to choose one animal from various groups. They complete a fact sheet on each animal and report their...
