Hands-On Wednesday: Crayon Melting Science

Crayon Melting Science

Crayons can be used for more than just coloring! Create a fun Valentine’s card while learning how different pigments, which give crayons their color, react differently to heat. Crayons with darker pigments, or colors, will melt faster than crayons with lighter pigments because they can absorb more infrared heat, but does this mean they will melt as fast with a hair dryer? Test a variety of colors to see which melt fastest or slowest with some crayon melting science to design your own Valentine’s Day card.

After School Spring 2016: Week 1

Building Gliders

At the first week of Spring 2016 After School, Girlstart girls explored the Engineering Design Process and built their own gliders! After they identified a problem question, brainstormed ideas, and built their prototypes, it was time to take off.

 

 

 

 

 

3, 2, 1, LAUNCH! Each plane was unique and took a different flight path.

 

 

 

 

 

 

 

 

 

 

 

Girls will be using the Engineering Design Process all semester long, as they build and create more amazing technology. We’re excited to see where their bravery, curiosity, and creativity will take them!

After School ‘to Go’ Spring 2016: Week 1

Crazy Catapults

It’s only the first week of Spring 2016’s After School To-Go, and Girlstart girls are already learning about simple machines and engineering! Girls used the Engineering Design Process to identify a problem question, research and brainstorm ideas, and build their own catapult prototype.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Girls evaluated their catapults and launching objects to compare and contrast how far each object traveled. We’re excited to see more cool technology, built by hand, from our Girlstart girls this semester!

Hands-On Wednesday: Soap Powered Boat

Soap Powered Boat

Create your own soap-powered boat to travel across the water’s surface. Soap is a surfactant, which means it breaks up the surface tension of water. When you put soap on the lightweight boat, the soap breaks up the surface tension on the water with enough force to move the boat forward. Now try out different kinds of soap to see which soap makes the boat go faster!
