In this mixtures worksheet, learners answer twenty three questions about student presentations on topics such as amalgams, homogenized milk, antifreeze and coolants, soaps and detergents and water softeners.

Learners study the Miller-Urey Experiment including its history and criticism.  In this origins of life lesson students repeat this experiment to see how it works.

High schoolers observe the rusting process in the lab. In this chemistry lesson, students rank metals according to their conductivity. They give real world applications of this activity.

Students observe the growth of a seed, predict what will happen when seeds are planted without soil, and conduct an experiment using a hydroponics system.

Pupils examine the effects different substances have on proteins. They test different molecules reaction to water. They discover how the amount of water affects the shape of the protein.

Students explore the mesosphere and lower thermosphere globally and achieve a major improvement in our understanding of the fundamental processes governing the energetics, chemistry, dynamics, and transport of the atmospheric region....

High schoolers are explained that thermophiles are organisms that have optimal growth temperatures above 50oC. They investigate the temperature ranges for the growth of common bacteria. Students answer the question of do either of these...

In this science activity, students match each type of scientist listed in the left-had column to its correct description found in the right-hand column. There are 34 different scientists to match on the sheet.

Students examine the consequences of behaviors and what the concept of trade offs are.  For this good decision lesson students read an article and answer questions on making good decisions. 

Students explore the potential challenges of living in space.  In this investigative lesson plan students search the Internet to locate 16 nations that are working together to build the Independent Space Station, then they divide...

In this science worksheet, students participate in an Earth Day activity by completing a crossword puzzle. Students read each clue. The answer which fits in the puzzle is provided in a scrambled word form. Students unscramble the words...

High schoolers collect samples of rainfall, cloud condensation, and water that trickles through the soil. These samples are tested for pH, conductivity, and the presence of sulfates, nitrates, calcium, and magnesium.

Eighth graders visit the Virtual Earthquake Web site and complete activities that demonstrate how geologists locate the epicenters of earthquakes. The site uses actual data from historic earthquakes.

Fourth graders determine, through laboratory activity, the presence or absence of glucose in a variety of plant leaves and stems. They work in groups and perform a three part laboratory which shows them how plants convert sunlighht to food.

Students compare water quality of different sources. They test water samples for odor, phosphates, pH, bacteria, and dissolved solids. they fill out a data table and answer questions about their findings.

Students participate in hands-on activities to explore the endocrine system. Students research and write about the endocrine system to demonstrate their knowledge. Handouts and worksheets are included in the lesson.

Young scholars study why plants are green and how water is transported in them. They examine how plants respond to different amounts of light.

Young scholars discover the concept of decomposition. They examine how it makes the soil more fertile and how it helps plants. They put a compost bin in their backyard and record their observations.

High schoolers identify Gram positive and Gram negative bacteria using staining techniques. Students research importance of identification of bacterial types in diagnosing bacterial diseases.

Students measure the pH of soil samples from a hypothetical site to locate a contaminant spill and will predict the direction of groundwater flow using mathematical modeling. They use the engineering design process to develop...

Students gain an understanding of earthquakes. They examine vocabulary associated with earthquakes, how earthquakes happen, and preventive measures taken to diminish damage or harm in the event that an earthquake should happen.

Fifth graders discuss the importance of water quality for humans and fish and make predictions about what happens to water that is polluted. In small groups, they conduct experiments to compare and contrast water that is unpolluted and...

Studentsbrainstorm ideas about Cancer and its couses. They read an article which describes communities in the United States that have been affected by high rates of cancer and information which describes hereditary factors that...

Students explore nutrient, bacterial, and toxic surface water pollution. They identify the amount of water they use each day and summarize the kinds of substances that cause water pollution. They predict what will happen in water...
