BLAST OFF!!!

                          BLAST OFF!!!

Last week on Wednesday the whole of Fifeshire  went outside and watched a rocket. We had a few problems along the way when the rocket would not blast off, but after a few adjustments it finally blasted off!

We also had a challenge to see who could be closest to 

 the rocket when it landed. We had to choose a spot to stand before the rocket blasted off. We were not allowed to move once it was lit.

The winner was Braydon from Room 6. He was the closest to the rocket when it landed.

Fair Testing - Sweet Dyes

We started with the petri dishes by adding a cm of Luke warm water into it, then we added two drops of white vinegar to it. Then Mrs. Binnie told us we needed to choose six Jelly Beans of the same colour. We had to get a cloth that we were trying to dye.  We had the choice of putting the cloth on top of the Jelly Beans or underneath.

My group decided to use the colour yellow. We put the jelly beans on top of the material and waited to see what would happen. We had to wait 3 minutes before putting the material on a paper towel.
The colour yellow didn't have a very good effect because it wasn't a very strong colour.
Since we got to change something in the experiment we decided to change from just one colour of jelly beans to multi-coloured and the effect was better than we thought.

The idea of this was to teach us about fair testing. We had to change one aspect of the investigation only, such as the colour of the Jelly Beans, or how much vinegar we put in, or the temperature of the water etc. We chose to change the colour of the Jelly Beans to multi-colour. Fair testing is about changing one thing and seeing the difference in what it has done. Fair Testing can also be when you're doing a time experiment that you do every thing the same.

We found out that purple and pink were very strong colours and made a very strong mark on the material I really enjoyed the whole thing!

                        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
