Student measure mass to discover how pennies have changed in their composition. In this measurement lesson, 8th graders investigate through an open-ended problem to discover how the US pennies composition changed in the 1980's.

Learners explore the idea of parallax. In this astronomy lesson, students study the distances of stars. They investigate how parallax can be used to determine these distances.

Students investigate the different methods used in integrated pest management. In this biology lesson, students evaluate experiments and case studies on IPM. They discuss the pros and cons of using this method.

Students determine the physical and chemical factors that affect plant growth. In this biology lesson, students explain the role of hormones in plants. They investigate how competition with other plants affect their growth.

Students investigate the different types of sundials and their history.  In this shadows and time of day lesson students build their own sundials. 

Students explore oxygen and its physical and chemical propeties.  In this investigative lesson students complete several experiments using oxygen.

Students investigate the formation of clouds and rain in this experiment. They decide how dust in the air helps to make clouds form and how dust helps meteorologists make forecasts.

Learners investigate the concepts of magnetism and its properties. They construct a magnet and test foods for iron content. Then students define the use of a motor and make their own electric motor while working in small groups. Then...

Students interpret and analyze data.  In this middle school mathematics lesson, students conduct an experiment in which they investigate which solar collector, black, white, or silver, absorbs the most heat.  Students examine...

In this human cells activity, 7th graders complete a science experiment using human cheek cells. Students sketch the cells at high and lower power and label the cell nucleus, cytoplasm, and cell membrane.

Students investigate various tree leaves and use a dichotomous key to classify the leaves. In this leaf classification lesson, students study various types of leaves and their Genus. Students record observations for each Genus.

Students investigate volcanoes. In this landforms lesson, students locate two volcanoes on a world map. Students compare and contrast the types of volcanoes by using various Internet sites.

Students investigate the attributes of scientists. In this scientific process lesson, students participate in a classroom activity that requires them to describe the jobs of scientists. Students discuss their findings. 

Students design their own wind turbine according to client's needs. In this science and technology lesson plan, students analyze the pros and cons of using wind power. They construct a model of their proposed wind turbine and present it...

Students investigate the celestial sphere and circumpolar motion. For this science lesson, students view an applet, The Celestial Sphere and Circumpolar Motion. Students discuss the Earth's rotation and stellar movement.

Students investigate the affect of soap and water temperature on surface tension.

Students create an accelerometer and take measurements of acceleration in a moving car. They study the car speeding up in a straight line, slowing in a straight line and curving at constant speed. They prepare a lab report showing...

Ninth graders investigate the structure of proteins and how it affects their function. They build a protein model with four helix units and describe how this structure aids the protein in doing its jobs.

Learners investigate the organisms of bacteria. They are given a culture of bacteria that can be observed under a microscope. The students make observations that are recorded. The lesson includes the mention of specific safety...
