Mini raft.

We were making a mini raft, here is our project. I hope you enjoy it, and maybe even learn something!      

Displacement Experiment

Prediction

We will be doing an experiment to show how water goes up or down with three shapes in it.

Sink or Float?

Sink or Float ?

Object	Prediction s-sink     i- in between      f-float	Result
orange	f	f
bolt	s	s
orange no skin	s	s
lemon	f	f
no skin lemon	s	f

Why do some things float while others sink?

Some things sink because they are heavy but lite things float.

Super tankers

Super tankers a one of the bigs posts in the word. They carry crude oil and other things.Crude oil is a car oil, other petrol like your lawnmower and plastic.did you know plastic is like your chromebook and your netbook?
 

Deep Sea Submersible

Submersible have wing, to fly not in the sky in the water.

They make deep flights in the water.

Sometimes the scientists use these for submarine exploration.

They are like miniature submarines with only one person inside.    

Swimming

I love swimming! This term i had 8 lessons with some amazing instructors. They taught me lots of skills, and my technique is getting better and better.

After getting changed,but before we get into the pool,we have a little rinse. We have to wait for our instates.when we were waiting we were shivering like an ice block.

When we were in the pools the instructors gave us a flutter board to  use.sometimes the instructors tells us to do arm circles, rocket arms and fast little kicks. Rocker arms is when you put your arms above your head and behind your ears, hands together. When you do this your body looks like a rocket and it will help us float.   

On the final day of swimming we had a relay race to see how much we had improved the instructor call six people at a time to see how good we are had. Learned of swimming lesson.

Thank Mr Burt for paying for professional coaches to teach us.
