Students ask questions about the nature of science as they experience a 'Fossil Hunt'. They reconstruct a book that has been literally destroyed, just as the fossil record has been changed by billions of years of geological processes.

Students analyze and discuss the evolutionary history of dinosaurs.  In this investigative instructional activity students monitor different organisms in the environment and analyze the pressures that affect the chances of...

Fifth graders are presented with three rocks and a variety of tools and are asked to investigate the properties of the rocks to see which rock is best for building tables and benches for a museum picnic area.

Students examine adaptation through a hands-on activity and determine how the gene pool can affect adaptability. They simulate a predator and prey relationship by going on a hunt for colored acetate disks. After a three minute hunt, they...

Eighth graders examine different solutions.  In this solution material instructional activity students complete a lab activity and several worksheets. 

Students examine the problem concerning the evolution of seed color in pinto bean plants "How does natural selection change the frequency of genes or traits over many generations"? Students work in teams to design an experiment that...

Students simulate the changes in a natural population of birds or other species. They establish baseline data of population fluctuation for a closed population with a stable food supply. They graph the data to complete their mutations.

Learners create a definition of eutrophication.  For this organic material lesson students work together to create a storyline.

Students explore vermi-composting. In this vermi-composting lesson, students listen to the story Diary of a Worm and discuss the parts of a worm. They create worm bins and add organic food for the worms to recycle. 

Students conduct observations using their five senses. In this science lesson, students describe different states of matter. They investigate the factors affecting mold growth.
