Sweeney, Ryan M.; Martin-Hansen, Lisa; Verma, Geeta; Dunkhase, John – Science Scope, 2009
Learning about osmosis and diffusion is often a challenging task for middle school students. Here the authors present a lesson that was converted from a "cookbook" lab (McLaughlin and Thompson 2007) into a more inquiry-oriented lab that uses inquiry teaching strategies and hands-on investigations to teach middle-grade students about osmosis and…

Taylor, Amy; Jones, Gail; Pearl, Thomas P. – Science Scope, 2008
Nanoscience, or the study of the world at the size of a billionth of a meter, has the potential to help students see how all of the sciences are related. Behavior of materials at the nanoscale differs from materials at the macroscale. This article introduces three nanoscale properties and how they relate to various science domains. Three…

Gordon, Jessica – Science Scope, 2008
Water is an essential resource for all living things. How we live on our watershed can impact water quantity and quality. It is important to recognize how humans alter watershed dynamics, but students often find it challenging to visualize watershed processes and understand how decisions that they make as individuals and together as a community…

Campbell, De Ann – Science Scope, 2007
Biotechnology is a fairly new concept for middle school students as well as teachers. If the latest craze of TV shows focused on crime scene investigation events were not so popular, the term and concept might be even obscure to the public. There is an increased presence of biotechnology in our daily surroundings that makes it practical and…

Schroeder, Carlos – Science Scope, 2007
Teaching science by means of inquiry-based projects has the potential to transform the science lab into a place of debate and discovery, but teachers run the risk of either leaving students to work too independently or forcing them to be too dependent on our guidance. To counter these challenges, the author implemented changes in the way topics…

Drouin, Pamela; Welty, David J.; Repeta, Daniel; Engle-Belknap, Cheryl A.; Cramer, Catherine; Frashure, Kim; Chen, Robert – Science Scope, 2006
In this article, the authors present a classroom experiment that was developed to introduce middle school learners to the carbon cycle. The experiment deals with transfer of CO[subscript 2] between liquid reservoirs and the effect CO[subscript 2] has on algae growth. It allows students to observe the influence of the carbon cycle on algae growth,…

Schaefers, John – Science Scope, 2006
An infrared (IR) thermometer lab offers the opportunity to give science students a chance to measure surface temperatures, utilizing off-the-shelf technology. Potential areas of study include astronomy (exoplanets), electromagnetic spectrum, chemistry, evaporation rates, anatomy, crystal formation, and water or liquids. This article presents one…
