                        ROCKET SCIENCE
In preparation for science fair, we conducted an experiment on balloon rockets.         

First we got all the supplies for the experiment.

straw

balloon

tape

string

 Method

 1. Cut the straw in half.

 2. Push one end of the string through the straw.

 3. Tie the other end of the string to something.

 4. Blow up the balloon.

 5.Tape the balloon to the straw.

 6. Let it GO!                                                    

Purpose

Some groups wanted to know how to make the balloon go faster.

Others wanted to know how to slow the rocket down.

The rest of the groups wanted to measure the speed of the rocket.

 Hypothesis                                                                                                                        

 One group thought that if the string was tilted it would slow the rocket.

 And another group thought that if you put less air in the it would slow the rocket down.

Conclusion

Some groups were wrong and some groups were right. Some were both wrong and right at the same time. 

 This is us having lots of fun as a class.                                          

                                                               


                                                                   



                                                         
                                                          

                                                     

We love rocket science.





                                                                                                                                           
    We got some interesting results but it was a lot of fun anyway ;).                                                                                                                                          file://localhost/Volumes/LocalHomes/room8imac/Desktop/IMG_0368. JPD
