How can you compare linear functions? The seventh installment of a 12-part module teaches learners how to compare linear functions whose representations are given in different ways. They use real-world functions and interpret features in...

Everybody loves video day! Grab your class's attention with this well-designed and engaging resource about graphing. The video introduces a scenario that will be graphed with a piecewise function, then makes a connection to domain...

New Horizons set forth on a mission to Pluto in 2006. Ten years later, the spacecraft is still on its way. Here, enthusiastic scholars predict what they will be like—likes, dislikes, hobbies, etc.—when New Horizons arrives at its...

You're only 10 minutes late? Do you know how much the universe has expanded in those 10 minutes? Scholars graph supernovae based on their redshift and see if the results verify Hubble's Law. If it does confirm it, the universe is...

Middle schoolers examine the effects of variables. They view a video which introduces the concepts, take part in an internet-based activity, then engage in a hands-on activity which allows them to practice what they have been studying.

Students examine the changes in the U.S. in the period of industrialization before the Civil War. They analyze census data, list/describe inventions and innovations, explore various websites, conduct a Factory Simulation activity, and...

Learners investigate the First U.S. Industrial Revolution. They identify positive and negative effects of early industrialization, read first-hand accounts, role-play and interview individuals, and participate in a debate.

For this Christopher Columbus worksheet, students utilize the Internet to access a specific website to find the answers to eight short answer questions associated with the voyages of Christopher Columbus.
