Have you ever wanted a robot assistant that could do all your household chores? Science fiction has been showing us such robots for decades, but they're still not available! What's taking so long? In this project you will investigate some of the challenges in programming a "robot" to do a simple household task, such as making a sandwich. Read more

How do driverless cars know what to do at an intersection? How do they know when they should stop and when it is their turn to go? What about yielding to pedestrians? In this activity, you will write your own algorithm, or list of steps, for a driverless car to follow when navigating through various road scenarios like stop signs, traffic lights, and roundabouts (traffic circles).

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

Are you curious about how public health officials think about and model how diseases like flu and COVID-19 move from one person to another? In this activity, you will use the kid-friendly programming language Scratch to write a simulation that uses bouncing dots to represent healthy and sick people. The simulation will show how we can take measures to slow the spread of a transmissible disease. Read more

How do driverless cars know how to recognize different road signs? They use something called machine learning. In this activity you will teach a computer to recognize different road signs using photos that you take yourself and a tool called Teachable Machine by Google®. The better the training data, the more accurately the program will be able to recognize different types of signs. Read more
