Biomedical Devices for the Eyes

Sometimes we all need a helping hand. Scholars get together to lend a hand in creating an assistive device that must be able to grab a hard-to-reach object. Now that's some help we could all use!

Blow your learners' minds with a sweet lesson on nanotechnology that uses sugar to demonstrate the difference nanoscale surface area makes in dissolving and crystal formation. Plenty of supportive background information is read to...

When given too much data to simply memorize, it helps to sort it into manageable groups. The second lesson plan in the six-part series of Cosmic Chemistry challenges groups of pupils to take a large amount of data and figure out how to...

View molecular structure for various compounds with three-dimensional color images. 

Let's get a closer look at DNA and other molecular structures. The first lesson in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The resource presents...

When you have to flow, you have to flow. The lesson introduces class members to microfluidic devices and their uses in medicine. They watch a short video on how the diameter affects the rate of flow. The worksheet has individuals...

Eighth graders explore and demonstrate an understanding of the factors that contribute to the efficient operation of mechanisms and simple machines. They design and make a mechanical toy device that moves a given object a specified...

While it is impossible to know both the speed and the location of an electron at the same time, Lewis dot structures enable people to visualize them. The video explains valence electrons, drawing Lewis dot symbols, knowing when dot...

Think you can solve the energy problem? You'll first need to know about current energy use. Analyzing a set of circle graphs lets scholars see where energy consumption is the greatest, both by sector and by household use. They develop a...

How does that bridge stay up? What are the forces acting on that column? This site helps students understand how structures can be built by having them build their own. Also provides images of real structures for kids to compare with...
