Third graders measure their feet and their parents' feet, record data on computer-generated graphs, and calculate and record mean, median, and mode.

Tenth graders examine the ecosystem of Lake Wilmar through three coordinated performance tasks. They first investigate the effects of pH on freshwater animals by comparing the zooplankton counts from three different areas. They then...

High schoolers collect and analyze data to study wavelengths of visible light. They cover Styrofoam cups with three different colors of sun filtering products and shine a lamp directly on the cups. They determine the most effective...

Students examine tadpoles at various stages of development. They make careful scientific observations and compare the changes that occur at five different phases of a frog's life.

Students are given three unknown samples and must perform two chemical tests in order to determine if the samples contains protein and/or starch. Students work with corrosive or toxic reagents.

Students study the contamination of drinking water and what human activities play a role in it.  In this environment lesson students complete worksheets and complete a lab activity. 

Students collect data on the cooling of water in two different test tubes, one that is wrapped in wet newspaper and one in dry newspaper. They then relate this cooling effect to the body's perspiration.

Students explain the historical significance of use of the scientific method in developing the first airplane and appreciate the process involved in developing a new technology.

Learners measure the effect of water temperature on the rate of a chemical reaction, similar to the interaction of a weak acid and carbonate rock, using hot water and effervescent antacid tablets.

Students participate in a hair analysis lab. Using a digital microscope, students compare and contrast hair samples. They determine if the hair samples are human or animal. After completing lab results sheets, students share their...

Fourth graders explore fractions. They compare different fractions using fraction bars. Students find equivalent fractions and they use fraction bars to visualize addition of fractions.

Ninth graders study the Big Bang theory.  In this big bang theory lesson students research the Internet and complete several activities and create a presentation.

Eighth graders examine two different types of tires and the effects of different factors on the amount of force needed to overcome sliding friction such as when the vehicle tries to stop.

Students use one of four absorbent products to separate as much of the oil and water mixture they are able to do. The purpose of this task is for students to collect and analyze data for the purpose of determining which absorbent is...

Small groups of students perform paper chromatography to separate food dyes into their component colors. Students perform the experiment and collect, organize, and represent their data to form an explanation of their outcomes. Students...

Students use their basic knowledge of physiology to analyze graphical data of paramecia under diverse conditions. From the data analysis, Students develop explanations of the animal's response to the concentration of different solutions...

Students determine the best material from which to make a jacket to keep the body warm in a cold, dry, windy climate. This task assesses the student's ability to perform an entire investigation. In this question the independent...

Students determine the average speed of a toy car as it travels six different distances set up by Students. Three trials are done for each distance. The only requirements is that the longest distance must be at least three times longer...

Students interpret a graph of ocean depths and topographic features. This task assesses students' abilities to interpret figures, organize and represent data, apply knowledge of scale to a profile, and apply theoretical knowledge.

Young scholars receive balloons representing the "Life Cycle of the Stars." As the attached script is read, students follow the directions for the color of balloon they are given. Young scholars chart the results for their star. They...

Students utilize technology for research. They research the potential causes of the sinking of the Hunley.

Students measure oxygen percentages in room air and air exhaled after they perform various activities. They explore various websites, and record and analyze the data from the experiments.

Students investigate Newton's Laws of Motion and the Law of Conservation of Energy. They examine how a ball and half-ball behave and relate these laws to what happens to the ball. Students produce a graph of the data collected and...

Eighth graders investigate what would happen to the length of a rubber band as more and more rings were hung on it. They base their explanation on what they observed, and as they develop cognitive skills, they should be able to...
