Students hypothesize about the nature of falling objects, design an experimental test to answer the question using everyday objects, analyze data to form conclusions, and infer that mass does not affect the speed of falling objects. This...

Students study the structure and habitat of the hydra in this lab lesson. Students determine if the hydra can be used as an indicator to detect pollution from automobile exhaust.

Students work together to design an experiment that compares and contrasts differnet plant cultivation systems. In groups, they evaluate the results of the experiment to discover if the cultivation system could be used in space. They...

Student design an experiment in order to determine where weeds grow the best. Through data collection and observations, they discover optimum conditions for weed growth, conditions that make it difficult for weeds to grow, and create...

Students study motion and how different variables can change the outcome.  In this motion instructional activity students answer questions about their experiment and see what the different variables did. 

Students, working in research teams, investigate the eating habits of crickets. They collect and record data and compare their methods and results with other groups by making tables or graphs. They sumarize their findings with posters or...

Students conduct a scientific investigation to determine if a magnet attracts paper clips through different materials. Students write out their procedures, collect data and present it in a table or chart, and analyze their results.

Students engage in a laboratory instructional activity in order to increase understanding of the impact of phosphates at the chemical and ecological levels. The lab exercise is completed with the goal of getting them to predict the...

Students create paper airplanes.

Students observe that movement of a solute in the solvent increases the rate of dissolution. They demonstrate that when the solute is broken into smaller pieces it dissolves faster.

Students view a video clip about the effects of El Nino. They work together to develop a question about weather folklore. They participate in an experiment that tests their hypothesis.

Young scholars experiment to define which environmental factors favor decomposition by soil microbes. They decompose carrots in dirt, weigh the carrots periodically to determine how long it takes. They look at how engineers use this type...

Young scholars design investigations to test various materials to prevent heat gain in frozen water. The task assess students' knowledge of scientific inquiry including the following skills: observation, data collection, measurement,...

Young scholars observe yeast fermentation using different energy source. In this chemistry lesson, students measure the gas collected in the balloon. They upload their observations on the internet so they can share it with kids across US.

Given investigation scenarios and lab procedures, students will identify independent variables, dependent variables, constants, and control groups.

Dozens of statistical terms are defined and illustrated in this glossary.
