SCIENTIFIC T Bag Rockets

WE HAVE LIFT OFF!!!!

After only launching 1 out of our 6 T-Bag Rockets on Tuesday, Room 10 put their Science Hats on a tried again.  

A few of the children believed a longer t-bag would make a difference...and it did!  

5 out of our 6 rockets flew up to 3 metres high.  

One rocket fell over and smoldered on the ground.  (See video below)

We think the rocket that tipped over didn't fly because the hot air escaped out the bottom and simply burnt on the launch pad.

Callan problem solved at home by using a different type of t-bag and succeeded in launching his rocket, but was unsure how or why it flew.  (See video below)

Callan's T-Bag Rocket

After changing the size of the t-bag and testing our new theory, we discussed the results and concluded that hot got trapped in the bottom of the t-bag and forced the smoldering t-bag to launch into the air. 

 We are learning that SCIENCE TESTING is all about only changing one thing at a time in our experiments so we can see what makes a difference.
