Hands-On Wednesday

Balancing Ball

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!

After School Spring 2017: Week 7

Solar Ovens

This week in Girlstart, the girls were able to explore alternative forms of energy and see one in action! They put their building hats on and became Civil Engineers as they created their very own solar ovens! 

 

They started off by learning the difference between renewable and nonrenewable energy. Following, they were given cards with different examples of energy sources and had to work together to place the cards into the two categories. The girls then learned why renewable resources are so important, specifically when it comes to the benefits they provide. This includes lowering the emission of carbon dioxide and other pollutants into the environment, which have negative effects on wildlife that were seen in action the week before with Freddy the Fish.

How Fold Mountains are Made

Have you ever looked at a mountain and wondered how it got so tall? If those mountains you were looking at were a part of the Rockies, Alps, Himalayas, or Andes, chances are that they were a fold mountain. In this investigation, you will create a model that will show exactly how these fold mountains are created. Grab some beach towels and check it out!

After School 'to Go' Spring 2017: Week 7

Biofuels

This week at After School To-Go, students investigated different energy sources as Biofuel Engineers! After reviewing concepts like alternative energy, fermentation, and nonrenewable and renewable resources, girls discussed common sources of energy. What makes a resource renewable or nonrenewable? How do countries acquire more nonrenewable resources? Students explored these and other questions to prepare for their biofuels experiment.
