How does this activity connect to STEM and today's Girl Day theme of Designing Fun: Theme Parks, Games and Music? Scientists and researchers have to be innovative problem-solvers, relying on their critical thinking skills to fix problems as they arise. This activity – building a catapult – requires that you bring your problem-solving skills and a joyful attitude to solve the task at hand.
Watch the video below for demonstrations of each of the 3 types of catapults and launchers.

The Children's Research Center (CRC) at The University of Texas at Austin works to understand how children develop and learn. When you visit us, children read books, solve puzzles, watch puppet shows, play video games, and engage in memory games with our researchers.
We rely on the help of Austin families and children to participate in our ongoing research studies. Our research studies are for infants to 17-year-olds, focusing on how children develop reading skills, how they think through and solve problems, how imagination and creativity are developed through play, how the brain changes, and more.

Due to COVID-19, our research studies have moved online for the safety and well-being of our families. Check out our website at http://bit.ly/ChildrensRese
We could not do our work without the help of families like yours – thank you!
