One of the factors that automotive engineers must consider is wind drag. The less wind drag, the more efficient the car will be. They perform many tests in wind tunnels, then refine their designs and test again. Using simple materials,...

Explore capillary action from different perspectives. In the fourth installment of a nine-part series, scholars perform several experiments to observe capillary action. They look at the meniscus of water in a glass, observe capillary...

Stability is key when building a bridge. Scholars explore the forces acting upon bridges through an analysis of Newton's Laws and Hooke's Law. The activity asks individuals to apply their learning by building a bridge of their own.

Bridge the gaps in your knowledge of bridges. Individuals learn about bridge types by building models. The activity introduces beam bridges, arch bridges, truss bridges, and suspension bridges.

Information on the biomedical use of nanotechnology, specifically in the detection and treatment of cancer, is the focus of a lesson that seems like it is out of a science fiction novel. Pupils learn about electrophoresis, which is used...

Science can be quite tasty. A delectable unit from NASA shows learners why it's important to consider food, nutrition, and health in space. Four lessons explore the idea in great depth, including testing cookie recipes. Along the way,...

What is the connection between sound and vibration? Learners find out as they conduct a series of experiments with instruments they create. The experiment is well explained, includes modifications for visuall and hearing impaired...

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...

Mix it up and engage learners in a lesson on music and physical science. Using cups, strings, guitars, and voice, the class will experiment with sound vibration and frequency. They'll use each instrument and fill out a worksheet that...
