As more people start living and working in space, we have to design our crew capsules and space habitats to keep people comfortable. That doesn’t just mean comfy beds and space sweatpants but also includes what our work environments and new homes will sound like on the inside. First, astronauts have to get to space using rockets, which generate a large amount of noise inside the crew capsule. Once they’re in space, astronauts are busy tending to many tasks. They perform daily tasks including… Read more

To slow the spread of COVID-19, the CDC recommends wearing a mask or cloth face covering—particularly in places where it is impossible to maintain social distancing (staying at least 6 feet away from others). This recommendation is for everyone age two or older (children under the age of two should not wear masks). Many instructions to make your own mask are available online. This activity will help you think through the process of designing and making a mask as an engineering problem.… Read more

Did you know that the seaweed you've seen in the ocean or even eaten as a snack is inspiring innovators to imagine new materials? Large brown algae, like kelp, contains polymers—long chains of molecules—that are more environmentally friendly than the ones in most plastics. These natural polymers (alginates) could eventually be used to create sustainable everyday objects. Try your hand at using a bit of chemistry to turn biodegradable polymers from algae into your own custom… Read more

Have you ever seen an arch structure in a building, such as over a doorway or surrounding large windows? Arches have been used in structural engineering since ancient times. In this activity you will test the strength of a naturally occurring arch shape: the shell of an egg. So grab some eggs and put them to good engineering use in trying to answer the following question: Just how much mass can an eggshell can support? Read more
