Hydrophobic Surfaces—Deposition and Analysis

For Teachers 9th - 12th Standards
Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

Protein Folding Exploring

For Students 9th - 12th Standards
The potential energy of peptides varies over time as they fold. An exploratory simulation encourages pupils to play with various strands of amino acids to observe the folding and potential energy levels. Young scientists generate all...

Protein Folding

For Students 9th - 12th Standards
Long strings of amino acids fold themselves into stable peptides. The simulation allows scholars to observe the process in multiple ways. Using hydrophobic, hydrophilic, or a combination of proteins in three different solutions, the...

Molecular Sorting

For Students 9th - 12th Standards
Can scientists sort molecules based on their interaction with oil and water? The simulation demonstrates how this is possible. Pupils decide when to insert a molecule and observe how they sort themselves based on polarity.

Polar and Non-Polar Interface

For Students 9th - 12th Standards
Why is there so much frozen water at Earth's poles? Because water is a polar molecule! Young scientists observe polar molecules moving in a mixture of oil and water. They see the changes in potential energy in the hydrophilic and...

Aerogels in Action

For Teachers 5th - 7th Standards
Model an oil spill cleanup. An engaging engineering lesson has groups using aerogels to simulate an oil spill cleanup (vegetable oil in water). Along the way, they learn about nanotechnology and hydrophilia/hydrophobia.
