Learners explore botany by participating in a seed experiment. In this plant nutrition lesson, students define several science experiment vocabulary terms like observation, treatment, and replicate. Learners utilize soaked seeds in a...

Learners complete a virtual lab to test for a corn mold that can lead to dangerous toxins. They walk through a detailed step-by-step procedure then see their findings. Throughout the activity, they learn how to use lab tools and practice...

Students act as chief research scientists with the responsibility of testing a new drug. Students design a controlled experiment to test a hypothetical experimental drug. Students write a clear, concise, and detailed plan to present to a...

Researchers think they have evidence of a new planet deep in our solar system that is the size of Neptune and orbits the sun far beyond Pluto. The orbit simulator shows the orbits of our well-known planets, as well as Pluto and the comet...

Students investigate what a controlled group is by creating an experiment.  In this plant growth instructional activity, students identify the different parts of a plant and discuss what is needed for a plant to be successfully...

Students conduct an experiment to determine which style of tape will stick the best.  In this controlled experiment lesson, students predict which tape will stick best to a marble that rolls over it, then they conduct the experiment...

Students create a biosphere using the computer program SImEarth. They work in small groups to create "Daisyworld" in which they model aspects of the Gaia hypothesis. They form a question to answer and choose variables to investigate in...

Students examine each soil sample and record observations. In this biology lesson, students design an experiment to test soil flow rate. They write a lab report about the experiment.

Students create and conduct experiments on a "classroom river habitat." They manipulate the biotic and abiotic factors so that they are able to compare an artificially prepared river model to a naturally occurring lotic ecosystem.

Students create an experiment about ozone levels using a Smog City Simulation on the Internet. They complete a worksheet and study associated vocabulary.

Students take on the role of epidemiologists. They investigate an "outbreak" in serious birth defects that occur in infants born to teenage girls. students discover a link between the use of the acne drug called Accutane and birth defects.

Role play community members who are both for and against the construction of a dam. Research the pros and cons and then hold a classroom debate. This activity ideally follows a series of stream studies, links to which are included. Use...

Students research principles of flight. They design their own paper airplanes and make predictions about the performance of different designs. Students keep track of their findings in an electronic journal.

Students apply an interactive smog visualization application, Smog City to see how ozone levels are related to population levels and emissions. They study associated vocabulary and complete a worksheet.
