First Aid Course

In room 18 we had a first aid course.  We learnt how to tie slings and wrap bandages.  We had to put on our sad faces for the photos.

The New Fish

The New Fish

In week 2 room 18 got four new fish from Matua Manu, the school caretaker.  There were two goldfish and two brown fish.  Sadly one of our goldfish have recently died.

Bean Plants

Dissection of my germinated bean.

In room 18 we planted some bean plants and we opened them up to see what was inside. My bean did not grow . It was nearly transparent and the young embryo was visibly growing. The food source was bendy and soft.

Water Assessment - Term One

My Water Assessment For Term One

H20

This is what I learnt about H20 (water) this term.  The word H20 means  two hydrogen atoms and  one oxygen atom is put together to create H20. Water comes in three different states, a solid, liquid or a gas.  This term we made oobleck.  Oobleck is a non-newtonian fluid so when pressure is applied it will turn to a solid. When less pressure is applied it will be liquified. Another experiment we did was layering liquids, layering liquids is all about the density of liquids. The liquids can have different densities by the thickness. Now let’s talk about  the water cycle. Baiscly the water cycle is about condensation, precipitation and evaporation. What happens is that the sun evaporates the water then the water gets stored up inside the clouds which is called  condensation, next when the clouds get too full it rains and causes precipitation. Getting back to the experiments have you ever wondered  how to bend H20? It is actually quite simple to bend H20, all you need is static electricity, but really what makes static electricity? Well it needs a negative charge and a positive charge. Can water walk? The answer is yes. The reason the water walks between the cups and paper towels is capillary action. Capillary action is caused by a liquid being able to flow through narrow spaces. Do you know how much work it takes for your drinking water to be safe? Much more than you think. We went to see it at the Pirongia Water Works. How it works is that the water is collected in Pirongia stream then goes through screening. Then goes into the first pond, where it gets rid of most of the bacteria. Next through to the second pond that gets rid of the extra nutrients. Then the algae and extra bits go to the bottom. Next it goes through another screening to get rid of all the particles. Then it goes through the UV ultra violet light treatment to get rid of the micro bits floating around. Then gets given out to Pirongia and Te Awamutu. And some gets stored in a big tank. This is everything I’ve learnt this term, but just to finish here is a photo.

Hope you enjoyed.

Baking Soda Boats

Week 4’s Scintillating Science Session

WALT: ...understand what a force is + (Chemical reactions + scientific procedure)?

A force is a push or a pull.

Forces can make object moves or stop, speed them up or slow them down. Forces can also make objects change direction or shape.

A lighter object needs less force to move than a heavier object

Friction is the force between two objects when you rub them together. Try rubbing your hands together? Do they get hot? You feel the friction between your hands as heat.

Air resistance and friction take time to slow an object down, if you want an object to stop quickly you need to apply further force, for example a brake on a bike.

What is happening with our boats?

Baking Soda Powered Boat

The Science bit

Vinegar (an acid ) and bicarbonate of soda ( an alkali ) react together to neutralise each other. This reaction releases carbon dioxide a gas which is the bubbles you see.

The force of the movement of the carbon dioxide backwards causes a reaction force which pushes the boat forwards.

                    

                                             

Taking Aim Writing

Taking Aim

Squelch, my foot buried itself in the cozy, colossal mud blanket on a cold day.  ‘’Welcome to archery at the narrows,’’ spoke a tall, lanky man, holding a big beige coloured bow.  Proudly but nervously I stepped up to take my turn.  I knew this was my time to shine.

My turn!  Before I knew it there was a notorious bow draped in my left

hand  I gripped it closely and tightly.  Carefully I inserted the long, thin arrow. ‘’Pull back!’’ yelled Ari continuously. Pulling  back the sticky elastic string I hesitated.  The arrow was like a prisoner trying to escape from his cell.  Aim, aim, aim…

Ping! The long arrow shot off as I pulled the trigger.  Poor target! The target must have experienced some excruciating pain. Score!

Oobleck

 

    We made oobleck on Friday.  In my group we 
    made a pinky orangey colour.  Oobleck is a 
  non utonium liquid and can be liquid or solid.
