How Sensitive Are The Lungs to Radon?

She had a terribly busy day converting oxygen into carbon dioxide; now she just needs a moment to breathe. In the activity, scholars review the function of the respiratory system and discuss bioengineering's role in medicine/health and...

After reading about how wind turbines work to collect clean energy, groups brainstorm and design their own windmill. Within the provided financial and physical constraints, groups must build a working windmill using only the materials...

Sound, vibrations, resonance, and frequency are explored as learners use music to foster scientific inquiry. They engage in three different sound experiments and follow up discussions to foster a better understanding of how musical...

Students investigate how pollution affects lung health. In this pollution and lung health lesson, students build lung models from a soda bottle and balloons, and then discuss how the emissions from fossil fuels can adversely affect lung...

In March 2009, NASA launched the Kepler Space Telescope to look for exoplanets. Almost immediately, it identified planets and has continued to work for many years. An informative video introduces this telescope, how it works, and shares...

Hop into exploration of a frog's anatomy with this collection of dissection resources. With the help of the included virtual dissection website, worksheets, and printable diagrams, students will have no problem navigating their way...

Create models of the infrared, visible, and ultraviolet portions of the electromagnetic spectrum. Working in small groups, your class can investigate metric conversions calculations. They will find the length of the waves in nanometers,...

Guidelines and worked examples for using the small x approximation to solve equilibrium problems with large Kc values. [14:04]

Students name the main components of the respiratory system. They write a reaction that contains complete sentences, and uses proper spelling and grammar, after viewing a video. Students define the following terms: lungs, respiration,...

How can heat power an engine? Scholars observe a heat engine working and control variables to determine the most efficient setup. They change the amount of heat input as well as the stroke length. Energy efficiency numbers prove the...
