Iris: Resonance: Modeling Resonance in Buildings Using Paper Model

Through the analysis of paper chromatography to separate ink from the pen found at the crime scene, learners analyze the different stains and through calculations determine the thief. 

Technology or engineering teams are given a task to design, construct, and test the efficiency of a structure that will foster an even temperature throughout an entire sunny day. Intended as a long-term project, pupils research, plan,...

After reading about the history and recycling of paper, creative crafters collaborate to think of a new process for making recycled paper. A complete teacher's guide and student worksheets are included. There is no written procedure for...

What volume of information about units of volume can your brain possibly hold? The third installment of an 11-part Math in Science video series introduces viewers to metric units of volume, using common objects as examples for...

A USGS seismologist demonstrates how to use spaghetti noodles and raisins to model building resonance during earthquake ground shaking. [1:21]

Cancerous tissues contain more water than normal tissue, which causes the cancerous tissue to resonate longer on the screen and be seen. High school learners can see how MRIs detect tumors in someone's head. Radio transmitters emit their...

Physical or earth scientists construct this clever contraption to demonstrate how size effects frequency. Several paper rings of various sizes are taped onto a board and shaken to create vibrations. The resonant frequencies are easily...

Start with a basic house created in JavaScript code and practice programming with loops as you add rows of windows, grass, flowers, or trees. How about some apples growing in the trees? You get the idea. Your coding students can let...

Learners investigate chemical reactions involved in making a blueprint. In this blueprint paper lesson plan, students expose blueprint paper with writing that has been soaked in a solution of potassium ferricyanide and iron (III)...

Construct a demonstration apparatus for your lesson on resonance. Instructions are provided here to assemble dowels and balls into swinging objects that have different frequencies. It is a neat visual to include during your lecture if...
