Second graders discuss the term "endangered". They identify the reasons some animals are in danger of being wiped out. They discover ways humans can help the species survive.

Learners plot the locations of fallout from two disasters that polluted much of the world's air. They plot the ash fallout from the 1980 Mt. St. Helen's eruption to see what the wind patterns in the United States look like overall. Next...

Learners predict the movement of an air borne pollutant using their understanding of air currents. They determine which governments and/or communities should be contacted to be forewarned. They also explore the properties of their...

Students investigate the motion of water currents by mapping the possible movement of messages cast into the ocean in bottles.They accurately plot the appearance of bottles on a world map and illustrate the flow of an ocean current...

Eighth graders identify the three main types of chemical bonds. In this chemistry instructional activity, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.

Students examine drops of water on several materials used on the outside of buildings. They make selective observations on and compare plastic, wood, brick, metal, roof tiles and glass.

Students explore the concept of density by trying to make a penny and other materials float.

Eighth graders determine which of two solutions is more acidic by adding each to a given base. Students have to apply this analysis process to a problem scenario involving an alien creature.

Students design and conduct investigations that illustrate the process of decomposition. After a lecture/demo, students simulate the process of soil composting in the classroom. They closely chart the decomposition of their soil.

Students learn the effects of friction and examine how certain lubricants can only be used with certain materials.

Third graders examine the difference between a food web and food chain. They also examine the importance of the sun in a food web and food chain. Students understand what happens when you remove parts of the chain.

In this science worksheet, students examine the words and concepts related to forces in order to solve the crossword puzzle. The new vocabulary can be acquired this way.

Middle schoolers estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays

Fifth graders investigate electricity and how it used in a circuit to be useful energy. They also use this investigation in order to understand how energy can change forms and still be considered useful if put into the right form.

Students demonstrate sound waves and make changes in the waves resulting in changes in pitch. Students associate changes in pitch in various "musical instruments"with size and shape and the sound waves they produce.

Students research how surface sea temperature changes throughout the year. They draw a time series of sea surface temperatures for each month of the year and a depth profile for a summer and winter month using an OceanExplorer Profiler...

Pupils collect chemical, physical, and biological data from a local lake throughout the year. In addition, students discuss the design of an experimental structure for water collection at several specific depths as well as assess the...

Seventh graders study the Erie Canal and New York state. They design a three-day vacation itinerary using tourism sites, which highlight historical facts and include the modern remains of the New York Canal system.

Learners use descriptive language to write riddles on their favorite seasonal subjects; they illustrate the "answers" to their riddles using the medium of their choice and compile both riddles and illustrations to create a book.

Students conduct a series of hands-on experiments that help them explain the role of lift in fixed-wing flight. They observe the flow of air and water around several surfaces and then consider the dynamics of airflow around an aircraft...

Students experiment to investigate the role in fixed-wing flight. They watch as air and water flow around surfaces to examine the dynamics of airflow around an aircraft wing.

Second graders examine how their choices affect the environment. They identify different types of pollution and its source. They ask questions to end the lesson.

Students design and construct a solar cooker. They use the Internet to research solar collectors and the process of changing light energy into heat energy.

Students collect data and make a frequency table, change ratios into percents, and analyze data to make predictions.
