Balloon Hovercraft

B E G I N N I N G	TITLE	Balloon Hovercraft
	QUESTION	How does a hovercraft hover?
	HYPOTHESIS	I predict that it’s going to move.

M I D D L E	EQUIPMENT  AND MATERIALS:	You need a dvd, bottle cap and a balloon.
	PROCEDURE:	Step 1: Using a hot glue gun,glue the bottle cap over the cd hole. Step 2: Blow up a balloon. When it is fully inflated twist the end over.  The end of the bottle cap. Step 3: Stretch the balloon over the end of the bottle cap. Step 4: Open up the cap and place the cd on the surface. Step 5: Untwist balloon and let go.
	OBSERVATIONS/RESULTS:	It hoved across on the table like a lawnmower.

CONCLUSION:

The air from the balloon creates a cushion of moving air between the disc and the CD and reduced the friction so the disc moved freely across the table.

Bridge Building

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 Harry, Veon, Kyle and me.  We used ice cream sticks, cardboard, egg boxes to build our bridge.

Here is a photo of our truss bridge.  What I like best about our bridge is  that it is an awesome bridge.

Speech

For the last two weeks we have been working on writing speeches.
My topic was Fire trucks.
We had to present them in front of our class.
I think I was good and I made it to the finals.

Have you ever wondered why fire trucks are so important in our communities? A fire truck is a vehicle that holds firefighters, lots of water and has hoses, ladders and equipment for cutting cars. I believe that fire trucks are important and here is why.

Firstly Fire trucks attend car accidents, scrub fires and house fires. At car crashes fire trucks have to use lots of equipment. In the lockers there is jaws of life, hoses, portable pumps, axes, shovels and brooms. This equipment helps the firefighters cut people out of their cars if they are trapped and clean up all the mess on the road.

Secondly fire trucks save people’s lives. They use hoses, axes and portable pumps to help people. They attend medical calls and help the ambulance. The truck holds special equipment to help people who are very sick.

Finally fire trucks take firefighters to attend calls when the fire siren goes. Fire trucks rush to fire calls with their siren on and lights flashing to help the people in our community.

I think fire trucks are important for the people in our community. They help save people’s lives and property. One day I would like to be a fireman and drive the fire truck to save my community.
