Week 4 trebuchet

Week four : Trebuchet.
In week four we are learning about the trebuchet which Is the same as a catapult, we were looking at the motions of the trebuchet. There is a little string that you pull to make the trebuchet work and then the object in the slinger will go flying in the air, with lots of air resistance.

Week 2 balloon rocket

Week two: Balloon rocket. We are learning about forces acting on the string. My observation of my balloon rocket was very cool, because the balloon on the wool was swirling around like a monkey, I thought the force acting on it was a thrust force, The balloon was also going slow I think it was, because of the thickness of the wool string. I wonder how fast it would speed across the string if it wasn't so thick.

Week 3 balloon rocket

Week three:Balloon rocket. This time when I did my balloon rocket I had fishing wire instead of wool string. The fishing wire had a different effect, on the balloon because the fishing wire was not as thick as the wool string. The balloon was going very fast and making a fart noise, I think it was because the air was coming out fast on the thrust of the balloon.

Week 1 slimeing the principal

Science journal 23.5.2017
      Week one: Sliming Mr Anderson with slime. In the morning on Tuesday, Miss Smith had a bucket of slime in her hands. Our class went to the hall, there was about 3 people from each class on the stage waiting to slime mr Anderson. When it was our classes turn, the slime was coming out of the bucket very slowly. It looked gooey, green, light blue and looked very sticky. What I've learnt from this is how to make slime.

Science journal week 8

Week 8: onager vs trebuchet
This week we have been studying the onager and the trebuchet. We were writing down ideas about what is the same about them and the differences about them using a compare and contrast map. We recorded the distance of the ball or hacky sack and looked at the forces of the catapults.

The similarities about the onager and the trebuchet is that they both use thrust. The trebuchet has a higher arch because it has a larger arm to throw the object in the sling really far. Where as the onager has a lower arch because it has a shorter arm than the Trebuchet.

The onager has more velocity when you pull the string on it because it's torsion powered. Whereas the trebuchet has less velocity because it's gravity powered.

 In conclusion the trebuchet would be better for getting over castle walls because it has a higher arc because of it’s high arm.

Inquiry

Inquiry reflection.
In He tangata, this year we have been focusing on being a responsible citizen. My inquiry project was to teach people cricket skills and games.
I think I am relational because when I was teaching other students skills, I had many ideas on how to teach them and what skills.
I'm proud of my inquiry project because I was teaching them skills and having fun at the same time.

Responsible citizen.

  Responsible citizen.
I think that I am a responsible citizen because I can do things
without being asked.
I can also help younger people than me by telling them
the right thing to do.
And if someone had a problem I would help them out.
I can move things to
the right place, listen, take my time on doing things and
think. Those things
I have said are why I am a responsible citizen.
