Science tech

LI: To test and conduct our own experiments with our own knowledge of rocket science. 

Today LS2 year 7s  went to tech and did science with Mrs Shamma and Mr Dunn and we learnt about rocket science and we made straw/blow rockets with plastic straws. but before we did this we did a brainstorm of words with Mrs Shamma, some of the words we wrote down  were Gravity, thrust, push, force, action and reaction and fins. We then worked with Mr Dunn and we bade straw rockets the first thing we did was to bend the tip of the larger straw and we made sure that we used a reasonable amount of tape or else it will add to the weight of our rocket, it is good to create a lighter rocket ship so that it can fly further. So we tried blowing our rocket without fins becuase our question was How many fins do we need for our rocket ships.

After that we created a hypothesis or prediction of how many fins that was suitable for our rockets. We tested our rocket with no fins 3 times and recorded our data in our work books, we then taped paper fins that we cut out onto the larger straw and tested the rocket with 2 fins 3 times and recorded our distances and we lastly tested our rockets with only 4 fins and tested 3 times and took record and the after that we had competition with all year 7 students to see who would get the furthest distance and the 3 winners would win a prize.
