The center of gravity of an object is the point at which weight is evenly dispersed and all sides are in balance. Using this simple trick, you can locate the center of gravity of any long object. Try changing the weight of opposite sides of the object and see if your fingers still reach its center of gravity!
This week at After School To-Go, students continued to learn about alternative sources of energy! As Wind Energy Engineers, girls worked together to design, build, and test a wind turbine’s ability to lift a load.
In continuing the learning about the role science plays in the environment, the girls took the role of ecologists and explored the relationship between plants, animals, and the environment. They explored the flow of energy through an ecosystem and the impact humans can have through various activities.
We all know that hair dryers are great to use after a shower, but today you will discover that they can also come in handy if you want to perform a neat science trick! In this “science snack” from the Exploratorium, you will see how air pressure impacts a ping pong ball that is balanced in an airstream from a hair dryer. Once you’ve mastered this you can even try it on a larger scale with a vacuum hose and beach ball!
