Students explore heart rates. They record pulse rates, predict which exercises cause a faster heart rate, make a chart, and graph the results. Students write an essay using the data to support their predictions. They write a hypothesis...

Students discuss and define the idea of a powerful image. In groups, they use the Internet and magazines to search for images they deem as powerful. They develop a hypothesis to why some people believe an image is powerful while others...

Pupils compare and contrast the cell cycle of frog eggs, normal cells, and cancer cells. They watch a video about early development of the frog embryo, generate a hypothesis in small groups, and listen to a teacher-led lecture. ...

Fourth graders realize that plants need light, water, and carbon dioxide to carry out photosynthesis. They participate in groups of 4 to plant (with materials provided) a test group of beans to compare to the control group, write a...

Learners study the function of lungs. In this lung function instructional activity, students complete an experiment using balloons to study the way lungs work. Learners study a diagram of their lungs and make a hypothesis for their lung...

Students examine the population of aphids. They identify adaptations they have made for their environment. They make predictions, test their hypothesis and collect information that either proves or disproves their theory.

Young scholars create their own bird study in their own schoolyard using the scientific method (see Testing a Hypothesis in Join the Project). Students do research in the library, at a local college, or on the Internet to determine the...

Middle schoolers make a prediction/hypothesis based on what you currently know about "mixed messages".

Pupils develop interviewing techniques--organize ideas and materials; record and summarize data; develop hypotheses about information collected; present results.

Students organize information obtained by observation and order it in historical sequence; to use evidence to support hypotheses.

Students form their own hypothesis about the relationships between force, mass, and acceleration for their dynamics cart system. They collect data and express it in a graphical format to visualize the relationships.

Students examine seasonal changes by watching tulip plant growth across the continent utilizing the Journey North website. They develop hypotheses as to why the plants emerge and grow where they do.

Students examine how evidence from fossils can be used in paleogeographic interpretation. They gain experience in developing multiple hypotheses.

Students explain that when forces on an object are balanced, the motion of object does not change. They describe how an object changes its motion when forces on it are unbalanced. They plan and conduct a scientific investigation to test...

Students observe the behavior of termites and draw conclusions about their behavior. They record data as to termite behavior and recognize elements in the experimental design which must include a hypothesis.

Students review the needs of animals, hypothesize the needs of plants, and set up experiments to test hypotheses.

Students examine an original engraving of a piece of equipment called, The Grasshopper Catcher. They describe how technologies developed in Iowa during the Industrial Revolution influenced farming practices, and develop hypotheses about...

Fifth graders create a 3D Pie graph using the Chart Wizard in Excel to represent their assigned states' data. They discuss the similarities and differences between states, and form a hypothesis on the relationship between location and...

Students research biographies and develop hypotheses about conditions for women at various points in history. They utilize a worksheet imbedded in this plan to organize their findings.

Second graders classify objects and formulate hypotheses regarding various materials and their magnetic properties. They complete a worksheet and watch a video.

Students search the Internet to find a site that contains an amortization table and make a hypothesis about the results of changing time and rate. They examine the affects of time and rate on a mortgage and discuss the difference in the...

Fifth graders compare and contrast the rate of soil erosion along water and along a vegetation area. They observe the differences and record their information and write a hypothesis of what they think happen if the erosion continues.

Learners brainstorm a list of possible actions that they could do to protect the water resources from pollution. They create hypotheses and conclusions by completing experiments and observing different pollutants.

Learners investigate the relationship between upstream influences in their watershed and the watershed's estuary. They apply the scientific process to test a hypothesis while examining the impact of upland activities on estuaries.
