This film chronicles the introduction of the hula hoop, a toy that set off one of the greatest fads in United States history. According to Wham-O, the manufacturer of the hoop, when the toy was first introduced in the late 1950s, over 25 million were sold in four months. This short scene illustrates the difference between a movement along a demand curve and a shift of the entire curve, a subtle point that many students struggle with.

This lesson guides students to learn the science behind cloning, explore the benefits and consequences of human cloning, and communicate their knowledge and points of view. Students begin by reading an article titled Primer on Ethics and Cloning by Dr. Glenn McGee, available for free on the AIBS's ActionBioscience.org website. The lesson provides questions for the instructor to guide a class discussion about the article. Instructors can then choose from different activities to engage students further in this issue. One activity has students role play advisory teams providing information to a committee on the ethical issues of human cloning. The teams conduct research online, keep a journal recording their research paths, and answer questions in presentation format. Another activity has students researching and presenting information on human cloning. Through their research students can learn about cloning technology and related laws, as well as the perspectives of groups or individual scientist's viewpoints. Included are web site evaluation worksheets that are useful for student internet searches on any topic.

HydroViz is an educational "virtual" hydrologic observatory developed for a "real" watershed and is based on integration of field data, remote sensing observations and computer simulations of hydrologic variables and processes. The main purpose of HydroViz is to support hydrology education in engineering and earth science courses.

During this activity students build a plastic pipette rocket. The first concept will to learn how igniting varying mixtures of hydrogen and oxygen will affect how far the rocket will fly. Second students will observe and manipulate variables to better understand the fundamental chemistry concepts: principles of combustion reactions, kinetics, stoichiometry, gas mixtures, rocketry, and different types of chemical reactions. Finally, students will assess their own understanding of these chemistry concepts by investigating how NASA scientists launch real rockets into space. One follow-up activity would be to investigate and collect data on a launching a heavier object at the school football field.

This lab gives students the opportunity to find the optimum mixture of hydrogen and oxygen as they react on a micro-scale.

This activity is an observation where students study clouds and predict the weather.

This activity is a teacher demonstration of an ice cream model representing glacier movement across Minnesota. Teacher/student questions and discussion should be encouraged during the demonstration.

Hands-on group activity in where children go outside to find clouds, document with pictures, and identify them.

This activity is a geology lab where students learn about fossils found in sedimentary rocks and show their understanding by writing a literary nonfiction paper from the perspective of one of those fossils.

This activity is designed for students to discover how making observations of the environment is the key to making sound predictions. Students will also learn how both positive and negative outcomes of these predictions can affect and shape future decisions.

This model-eliciting activity (MEA) challenges students to develop a model for predicting the characteristics of a person who has committed a crime. Students work with real data on shoe length, height, and gender to develop the model. Students write a report to the crime victim that identifies a suspect and justifies their decision. The activity sets the stage for students to learn about regression models, and reinforces their understanding of central tendency and variability. It is suggested that this activity be used prior to a formal introduction to linear relationships.

This activity is a kindergarten field and classroom investigation where students make observations, collect data and share conclusions that shows they understand that the sun is a source of light.

While working in groups to facilitate peer tutoring, students use samples of four igneous rocks (gabbro, basalt, granite, and rhyolite) to observe differences in texture, color and grain size and make inferences about the relative cooling histories and silica content associated with each magma type.

Spreadsheets across the Curriculum Module. Students use spreadsheets to analyze data on software piracy rates in various regions throughout the world

This activity is a student based inquiry looking at various natural disasters and their impact.

Based on a fable about government debt, students identify the relevance of crowding out, monetizing a debt, external debt, and stimulus spending.

This context-rich problem helps students to apply the characteristics of imperfect competition to a real world setting.

This activity is a classroom investigation where students predict, explore and evaluate what happens to water as it travels through the water cycle.

By presenting the students with fossils and other earth materials and giving clues as to their origin, they will be able to identify the fossils and materials and be able to form a hypothesis as to how they were formed and what it was before preservation.
