High schoolers investigate plant reproduction, pollen collection and identification. They collect pollen samples over a twenty four hour period and examine them under a microscope.

In groups, students create their own scientific impact experiments using ordinary materials, and observe and measure results with a variety of impacting bodies and velocities.

Students explore what happens to water as it goes from solid to liquid and back. In this state of matter lesson, students observe, measure, and describe water as it changes state.

Pupils evaluate the importance of hormones in living things. In this biology lesson, students experiment on carrots to differentiate how humans and plants reproduce. They collect data from experiment to answer analysis questions.

Eighth graders compare and contrast the three different types of rock. For this earth science lesson, 8th graders classify rock samples according to their correct rock type. They design their own data collection table.

Students discover the motion of a sphere on an inclined plane and discover basic relationships involving distance, time, speed(velocity), and acceleration.

Students determine the monotonicity and concavity properties of a function, then apply the First Derivative Test and draw conclusions about the first and second derivatives from these properties.

Students explore rotating frames of reference, focusing on the weightless environment in space and the Coriolis force.

Students gain an understanding of Kepler's 2nd law--that planets (and satellites) move fastest at their closest approach to the center of attraction, and slow down when far away. They explore the concepts of "potential energy" and...

High schoolers explain that planets actually orbit the center of gravity of the solar system, and that distant planets may be detected by motions of their central star around the centers of gravity of their planetary systems.

Learners explore how the amount of sunlight and heat change in areas that are shaded.

Students observe stars in the night sky and stargaze on their own.

Students explore orbital velocities and how they vary along each orbit, according to Kepler's Second Law.

Students contrast a weedy annual grassland of introduced species with an undisturbed, ancient plant community of native bunchgrasses and wildflowers.

Sixth graders develop a reasonable hypothesis for a fictional science fair investigation. 'Raquel' is going to grow radishes and test for the best way to nourish them. They create a bar graph and write conclusions.

Seventh graders discuss continuity and change, identify various plant materials, and compare and contrast ways in which early people used plants in Texas in prehistoric times with ways that modern man in Texas uses plants today.

Students perform an experiment using brown paper bags to determine which foods have oil in them. This task assesses student's abilities to make simple observations and inferences from them.

Students make simple observations, test mixtures, and make generalized inferences from their observations. They observe bleeding of colored inks with water.

Students determine a baseline pulse rate then chart the changes in rate with exercise. They describe the changes and develop a rationale for their observations. The task assesses students' abilities to make simple observations, determine...

Students collaborate to gather information about the geography, history, economy, climate, culture, and other aspects of life on the island of Eleuthera.

Fifth graders identify great Americans to nominate as the "Greatest American Who Ever Lived." They examine several sources, print and non-print. Students use gathered information to explain why some sources are used more than others....

Students use the scientific inquiry method to examine the ecosystems and biomes in Illinois. Using the characteristics of a local habitat, they identify the best conditions for an ecosystem to survive and how a slight change can damage...

High schoolers use the internet to research articles on garbage, landfills and the environment. In groups, they identify ways to conserve or recycle materials found in landfills and determine the future of a local landfill. They share...

Young scholars investigate the status of private schools in Utah. This done by looking at the public school system and make comparisons. The question of private schools being better is not clear and many factors need to be considered in...
