Koru Art

We made koru art with whaea rose  by  cutting cardboard steylafoam  and printing it on paper to create our koru template.  My koru represents new life and Aroha.  I really like the native birds in my art work because they represent NZ.  Here is a photo of me and my colourful, koru art .

TITLE
Balloon Hovercraft
QUESTION:
How does a hovercraft hover?
 HYPOTHESIS

I predict that the balloon Hovercraft  is going to stay on the table because  it has no air pushing it up .

EQUIPMENT AND MATERIALS:
We need a cd water bottle lid and a balloon .

PROCEDURE:
Step 1: Hot glue the bottle cap over the cd hole.
Step 2: Blow up  a balloon .  When it is fully inflated  twist the end so no air comes out .
Step 3:  stretch  the balloon  end over the bottle lid.
Step 4: Open up the cap and place the cd on a table.
Step 5: Untwist balloon  and let go .

OBSERVATIONS/RESULTS:
I found out that the hovercraft made a cushion of puff between the table.

CONCLUSION:
The air from the balloon creates a cushion of moving air between the disc and the surface  and reduces  the friction  across the surface.

Bridge Buliding

We have been learning about forces and how they help shape the sort of bridges that we build.  

We learned that there are three main types of bridge design; beam, truss and suspension.  Using this knowledge we designed and built our own bridges.

Miss Fletcher set the challenge that our bridges had to be 30 cm long and strong enough to hold an object.

In my group there were Sienna M and Nicole.  We used ice block sticks to make the ramp and the triangles and egg cartoons for the base to build our bridge.

Here is a photo of our truss bridge that we named Layenna Foster bridge.  What I like best about our bridge is the triangles on the side.
