See the water filtration system up close with a fun science experiment. Young scientists work for several class periods to design a water filter using household objects, and then decide which filter material would be most effective...

Students identify principles behind acid-base reactions. They predict factors that may affect an acid-base reaction. Students identify questions and concepts that guide scientific investigations.

Eighth graders investigate the water cycle and its processes. They examine temperature and precipiation data to classify climate of ten cities. They then create a climate map of the world.

During an inquiry-based lesson, scholars decide which variable to test and then design an experiment to determine the needs of producers. After two weeks, they complete a full analysis and research paper.

Fifth graders focus on the various types of fish living in different water environments. In groups, they research the different methods used to fish and participate in experiments to determine the effects of mercury on fish, the...

Students design, build, and test the specifications (water displacement and load line) for a model boat. The lesson focuses especially on integrating design principles with inquiry-based experimental skills.

Can a sidewalk increase the amount of pollution in local streams? Scholars learn the answer to this question though research and experimentation in the fifth unit in the six-part series. Pupils study runoff, impervious surfaces, and the...

Take your science class on a hypothetical field trip to Mars with an engaging astronomy lesson. After first learning about NASA's Mars rover missions, young scientists plan their own scientific investigations of Earth's...

This project provides students the opportunity to investigate parasites as a possible cause of the observed frog deformities. It asks students to view web-based evidence and interpret whether it supports the parasite hypothesis. Students...

Investigate deep sea discovery through the emerging technology being built.  For this physical science lesson, students analyze the different types of motion available in the human arm.  Students research educational websites...

Students create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...

Fifth graders study dehydration and dehydration of foods. They measure the amount of water lost from fruits as they are dehydrated. They use desktop publishing software to design an advertisement for dehydrated fruit after researching...

Students practice bleaching recycled fibers. Using colored copy paper, they cut it into strips and put it in a blender with water. They filter the pulp and stir in the bleach. They compare the original paper with the bleached sample...

Students discuss what happens to their wastewater. They read about the wastewater treatment process. Students are asked what types of things get flushed down toilets or goes down drains in sinks and showers. They are taught what happens...

Have you ever tried to light ice on fire? With methane hydrate, you can do exactly that. The ice forms with methane inside so it looks like ice, but is able to burn. The activity uses group research and a hands-on activity to help...

Learners use a model to conduct an experiment involving dam construction. Based on their observations, they draw conclusions about social, economic, and and environmental issues and make a decision concerning dam location. As a group,...

Young scholars use this design the illustrate how ink can be separated into its component chemicals using paper chromatography. They use five unknown samples of ink on pre-labeled chromatography strips are provided to students. Young...

Students learn the importance of caring for eggs as they hatch chickens. In this egg hatching lesson, students observe what happens when eggs are hatched into chickens by completing a e-worksheet and watching a web based movie.

Students explore Earth science by conducting an energy experiment in class. In this windmill lesson, students identify how wind has been used to pump water throughout history and the latest developments wind energy has produced. Students...

Students practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All...

Students compare the growth of watermelon from commercial seeds and those harvested from a watermelon. They complete science journals showing these comparisons based on the data they collect.

Students use this worksheet with the videodisk from Video discovery titled Evolution: Inquiries into Biology and Earth Science.Written because there is no computerized control program available, it is to be used with a standard videodisk...

Learners explore biology by creating a poster with classmates. In this oceanography lesson, students identify the importance of coral reefs to the ocean's ecology and examine a food web of ocean animals. Learners define a list of...

Students discover new ways to preserve the ecosystem by completing graphic organizers.  In this environmental instructional activity, students read an article from the Natural Inquirer in small groups and fill out a graphic...
