Science in the Library

Today we made videogames using Scratch, based on the infamous "Flappy Bird" videogame that brought its creators notoriety and established them in the halls of memorable bad game design forever :) We followed a tutorial I created and chose new sprites for our flappy character--many kids chose airplanes, fish, or other animals, and a few chose bats. The end code looks something like this (this is just the code for the bat that flies through the pipes): The final product is supposed to work like this (click on the picture and you'll be taken to the game which you can play): If you'd like to see the kids' projects they are posted here: Pasadena Library Kids' Blog The kids did a great job. Even one child who was not really very experienced with Scratch turned out to be quite sharp and able to follow all the difficult instructions. Despite having a lot of technical difficulties, almost everyone was able to go home with a finished game emailed to the...

For today's Curiosity Machine classes, our last meeting of the four-week session, we did an exciting project from the Curiosity Machine website: balloon helicopters ! We learned about different kinds of energy, particularly elastic potential energy. Elastic potential energy is the potential energy stored when you bend, stretch or deform an object, and that energy converts to kinetic energy as the object bounces back. Here's a great website that explains it pretty well: Physics 20 Project . We discussed examples of elastic potential energy using a Family Feud presentation I made on Scratch. You can click on the image below to see the project, though it's supposed to be used as a tool for discussion: The project itself was challenging and I'm glad I worked on my sample ahead of time. But it's so exciting to see those balloons fly! First, you have to cut a boba straw to about the same length as the rubber band you plan to use (when it's at equilibriu...

This summer I tried a new science workshop at the Pasadena Central Library, for tweens ages 9 and up, using the website http://www.curiositymachine.org . This is a great website for librarians, teachers and homeschooling parents, with its collection of projects, how-to videos, and opportunities for children to interact with scientists and get feedback on their projects. Free science classes are definitely in high demand, and even after I split it up into two classes the spots filled up right away! We started each class learning about some science concept and then applying what we learned to a hands-on challenge. We learned about Newton’s laws of motion, tessellations, the aerodynamics of bird flight, and simple machines. We: Shot stomp rockets, Made bird wings that could be flapped hard enough to rotate us around in an office chair, Engineered honeycomb structures strong enough to hold a stack of dictionaries, And designed sharp levers for picking up and breaking e...
