Hands-On Wednesday: CO2 Extinguisher

Try a new way of blowing out a fire by using baking soda and vinegar in this cool chemical reaction. When combined, these two materials make carbonic acid which is quickly converted into CO2. When you tilt your container, you are pouring CO2 into the flame. This causes it to blow out! Don’t forget to have some adult supervision, and most of all, have fun!

Houston, TX – B!irthday Bash at Discovery Green

Discovery Green is celebrating a decade of free events at its 10th Birthday Party! Girlstart’s Discovery Green initiative includes fun hands-on STEM activities that foster general awareness about STEM and encourage children and families to recognize that ‘STEM is everywhere.’

Check out Girlstart’s activities at this free event:

Parachutes: Have you ever considered skydiving? Experienced skydivers know that the most important part of jumping out of a plane at extreme heights is having a reliable parachute to slow them down. Use your engineering skills to design, test, and revise a parachute that will get your skydiver safely to the ground!

Sound Sandwich: Create your own musical instrument using tongue depressors, rubber bands, and a straw to explore how sound is caused by vibrations. Sound moves in waves, and different sized waves produce different pitches of sound. Experiment with your Sound Sandwich to find the perfect tune to play for your friends!
