PBL Evaluation
Water Safety Afternoon
For PBL my group ran a water safety afternoon at Hornby Primary for 22 year 6's. We did activities on the field, and activities in the pool. Overall it was really successful, there were no problems and the kids really enjoyed themselves. On the field we did some relays and played capture the flag. They got stuck into the relays and were super excited when they won. They got really competitive in capture the flag, and had heaps of fun.
Our action plan consisted of four steps: contacting the school, making a plan, writing a newsletter, and getting equipment. We achieved them all by each deadline, making it easier to complete our big goal: the afternoon. We all worked together as a team and all put work into each checkpoint, which make it easier for us to get the work done.
We believe that our afternoon taught the kids some new knowledge about being safe in the water, and also taught them how to work as a team. At the start of the afternoon we spent a bit of time talking about water safety, and asked them a few questions which they surprisingly knew the answers to. The activities we did involved working as a team, and they were all working really well together by the end of the afternoon.
Next time I think I would spend more time finding better and more educational activities, as we struggled to find activities for the field that involved water safety. We would also spend a bit more time going over being safe in the water, and try to keep them engaged as they were getting restless after a small amount of time. But in my opinion we were really successful, and there isn't much I would change.

Water Safety Afternoon at HPS
On Thursday the 30th of November from 1pm to 2:30pm, we ran a water safety afternoon at Hornby Primary School with 23 of their year 6's. Originally we were supposed to have 40 students and so we were going to have 2 groups, but we had to wing it and have only one group. For the first part we did some relays and played capture the flag on the field, and for the second part we did some games and skills in the pool. Overall the kids really enjoyed it, and had a better understanding of water safety.

Email Hornby Primary
On the 16th of October, we wrote and sent an email to Hornby Primary asking for permission to run our event. In our email we described the activities we will be running. We didn't get a reply for the email, so we rang the office and we organised a meeting with the principal. At the meeting we discussed possible dates for the event, numbers of students, and what activities we will be running. The meeting was successful, and we will be running the event in week 7 or 8. The event will happen around lunch time, one activity will be before lunch, and one will be after. The principal will email us before the end of the week with a date.
Update:
The principal has emailed us, and we will be running the event on Thursday the 30th of November from 1pm to 3pm.

Why we chose this topic:
Water safety is a big issue in New Zealand as well as the world. So many drownings have been recorded other the years because so many people have no water safety skills. This years drowning toll (as of Nov. 13) is at 59, in 2016 there were 108, in 2015 there were 113, in 2014 there were 71, and in 2013 there were 107. We want to make kids aware of the problem and teach them some skills while also having fun.
Who is affected?
In the first half of 2017, there were 47 drownings in New Zealand. 10% of those were kids under 5, 18% was 15-24 year olds, and 71% was 25+. 84% were males. Males above 25 years have been involved in the most drownings.

What are the issues?
Because young and old these days don’t have enough water safety knowledge, drownings are becoming more and more common. People are going out to the beach, rivers, and swimming pools with no safety knowledge, and are being put in situations that they don’t know how to handle.
When and how did this start?
Drowning has always been a huge problem in New Zealand, and we have a higher drowning rate here than Australia, the U.S, and the UK. This years drowning toll (as of Nov. 13) is at 59, in 2016 there were 108, in 2015 there were 113, in 2014 there were 71, and in 2013 there were 107. It doesn’t seem the problem is improving, and it may get worse as the years go on.
Where is it happening?
All over the world drowning has become a huge problem. New Zealand has quite a high rate, as we are an island. The most common places drownings occur are in rivers, beaches, swimming pools, and water holes. The top of the North Island is most susceptible to drownings. The South Island had barely any in the past few years, while the North Island had many.
Why is it happening?
Drownings are becoming more and more frequent because people young and old have no water safety knowledge. While young people occasionally have water safety lessons, they usually cost a bit of money, when they should be part of the school curriculum. Many adults think it isn’t important to know how to swim, so they put it off until it’s too late.
Our big impact action:
We will be planning and executing a fun water safety afternoon at Hornby Primary for the year 5's and 6's, to teach young students how to be water safe, to work in teams, and to have fun.
Our desired impact:
We want young people to be aware of the problem so that they can share it around and try to improve it. We want them to gain some skills so if they are put in a tough situation in water they know how to save themselves and others. We also want to prevent drownings.

Science - Earth Science
Earth Science
Earths crust is the coolest layer, while the inner core is the hottest.
There are two parts of the mantle, the upper mantle and the lower mantle. The lower is hotter, and convection currents cause heat from the bottom half to rise to the top, heating the crust and causing movement in the tectonic plates of Earth.
In the 1950's, Alfred Wegener thought up the theory of Plate Tectonics. He believed that the continents of North America, South America, Africa, Antarctica, Africa, India, Australia, Europe, and Asia all used to be connected in one big super continent called Pangea. He had lots of evidence backing this theory, but the strongest is the fossil evidence. All animals of the fossils mentioned were land animals, so they couldn't swim over oceans. Fossil remains of Cynognathus were found in both South America and Africa. Remains of Mesosaurus were found in South America and Africa. Traces of Lystrosaurus were found in India, Africa, and Antarctica. And most importantly, Fossils of Glossopteris were found in all five of the continents: South America, Africa, India, Australia, AND Antarctica.

A Challenge I Have Faced
A Challenge I Have Faced
It was a chilly, wintry morning, and I was standing alone at the starting line. I was a small fish in a big pond, surrounded by sharks. I was about to compete in the 10km Christchurch Marathon run, and I was a petrified student about to sit an exam. I had barely trained, and I was unfit, unprepared, and unaware of the pain I was about to go through. My insides were butterflies, fluttering around in nervousness. I could hear other competitors mummering around me, and I could see the dark rain clouds threatening to empty themselves down on us. The hosts voice was roaring through the speakers, giving us a rundown of the race. Then he started counting down, and everyone joined in simultaneously. Six, five, four, three, they called like children chorusing good morning to the teacher. Boom! The gun went off, and the race had started. We all moved through the gates like cattle being rounded up. Some sprinted off to lead the pack while others, including me, started off at a reasonable jog. My goal was to get through the whole race without stopping, but I wasn’t too convinced I would be able to. I was estimating that it would take me about 1:45, which is pretty poor, but I wasn’t at all prepared.
After the first one or two kilometres, the misery began. I had never been a keen runner, and I wanted to give up right then and there, but I knew I had to keep going. Rain was pelting down, and it felt like it would never end. I fought through the torture for six kilometres, then I passed a sign that said Two Kilometres To Go. I cried in despair, I still had so long to go! My legs were aching, and my heart was beating so fast I thought it was going to burst through its cage and out my chest. I could feel sweat dripping down my skin, and my mouth was dry and parched. My feet were dragging, and my earphones, once my motivators, dangled limply. I pushed on, my mind ticking like a clock, willing my legs to keep moving, willing my heart to stay strong. I ran through the pain and exhaustion, and finally arrived at the home stretch.
I sprinted as fast as my legs could handle, and my heart almost stopped when I saw the timer. 1:03! I had done it in an hour! I dashed through the finish line as the announcer called my name, and I almost fell to the ground in relief. My head whooshed as I came to a stop, and I was dizzy and aching. My legs were jelly, wobbling and quivering, but I was so proud, it felt as if I could run ten more! My dad ran over and hugged me, and I was as elated as a puppy with a new toy. I was victorious, a lion who had just captured his prey! I was dripping wet, caked in sweat, and as run down as a house just hit by a hurricane, but I was also dizzy with content. All around me were glorious competitors who were either buzzing with excitement, or laying limply and defeated on the ground. I could hear encouragements and congratulations, and the whole atmosphere was thrilling. I will definitely be back next year!

The Lonely Island
Have you ever felt completely and utterly alone? Well, I never thought I would ever feel so isolated, until one month ago… It all started December 12th. As I sluggishly boarded my 2:00am flight to the Bahamas, I felt this weird feeling in the pit of my stomach. My insides were butterflies, fluttering around in wariness and suspicion. I was on my way to see my mum! So why were my thoughts grey skies instead of rainbows? “Come along honey.” A worker called, “You don’t want to miss your flight!” I dismissed my eerie thoughts, and eagerly strolled down the airbridge. I took my seat as jubilant as a puppy with a new toy. After 19 torturous hours of a bumpy ride, we had finally arrived in the Caribbean! But my excitement and relief were short lived as right after the announcement, the lights started flickering and everyone panicked. The aircraft started lurching, and the crew were all running around like headless chickens trying to keep everyone calm. After one loud thud, the plane went as dark as the night sky, and I heard a scream. Suddenly we were falling, and then… everything went black.
Silence. Then it all came back to me. “Everyone stay calm!” Cried a flustered flight attendant. But her cry fell on deaf ears. We were all panicking preschoolers, grabbing hold of the seats that might as well have been feathers. All around me, loved ones were clutching each other, saying their final goodbyes. As for me, well I was scrambling for a handhold, a lifeline, some kind of salvation. Then we hit the ground. After reliving that dreadful moment, I slowly opened my eyes. Then I shrieked. All around me were broken pieces, lives ruined. A strangled cry escaped my lips, tears ran down my face like raindrops in a storm. I looked around in despair. Forest green shrubs, trees, and bushes enveloped me in a small island as deserted as no man's land. I was alone.
I was an astronaut in space, so detached from the world, from my home. Am I going to be stranded here forever? I looked around at all the lifeless bodies limply laying on the shallow, seashore, and realised I had no time to grieve. I needed to get out of there.
After looking through all the supplies I had that hadn’t been destroyed in the crash, I had acquired two apples, a bottle of water, a blanket, and some spare clothes. I searched and searched, finding my way through the murky, misty forest until I was a marathon runner that had just finished his race. Finally, I uncovered a small cave behind a wispy willow tree, and lay my supplies down on the floor that had a soft sandy surface. I took a long, well-earned gulp of water, and got prepared for the long afternoon ahead. I trekked back through the thick forest, but this time I knew where I was headed so it wasn’t so much of an effort. When I reached the shore, I was again hit by the overwhelming sense of tragedy over the loss of all these people. These daughters, these fathers, these sisters, these sons. But I had to get on with life, or I would never beat this island. I gave them one last long look, “Rest in peace.” Then, I walked back to the forest. I spent hours in there, collecting berries, coconuts, and bananas, and gathering flax, sticks, and big leaves. I took my discoveries back to my cave, and did some decorating.
After spending a couple of weeks on the island, I had started to become quite fond of it. But that didn’t stop the craziness. I had been away from civilization for too long, and I had a feeling that I would never return home. But I was wrong about that. One morning after I had eaten and cleaned myself up, I heard a shout. My heart leaped like a tiger pouncing at its prey. I sprinted down the beach, calling out to my savior, my hero. But I couldn’t see anyone. My stomach dropped, was I starting to hear things? Another shout, this time clearer. “Honey? Honey wake up, we’ve arrived.”
That’s when I awoke. I was perched on an airplane seat? My eyes widened in surprise, like a deer caught in headlights, as I realized it was all just a dream, and I had arrived in the Bahamas. But it was so vivid, so real. I stood up, and exited the flight, putting it all behind me. Well, until the next time I fell asleep…..

English - Recount of Silver Ferns vs England Roses Game
English - Recount of the game under the captain of NZ, Katrina Grant's point of view.
NZ Silver Ferns vs England Roses
With two minutes left we were down 47-45. Whitney fired the ball down to Bailey. She caught it in close range of the hoop, sweet we only need one more turn over! But as my mind wandered to the flaws in the teams play tonight, the crowd went into an uproar, Bailey missed from right under the hoop, and Geva Mentor leaped and stole the rebound right from her fingertips! Suddenly, the ball flew down to my end of the court. Jane and I gave it our all, but it just wasn't enough. Kadeen Corbin sent the ball straight into the hoop, sealing the test win for England at 49-45. After a torturous center pass, the final whistle blew, and my defeated team warily shook hands with the victors and glumly walked to the sideline with their heads down. Looks like we have a lot to work on at training!

Science - Making Table Salt
Making Table Salt
Aim:
To produce sodium chloride crystals by neutralizing an acid with a base.
Method:
1. Measure 10ml of Hydrochloric acid (HCl) in the small measuring cylinder and pour into a beaker.
2. Add sodium hydroxide (NaOH) to the acid a few drops at a time while stirring with a glass stirring rod.
3. Use the glass stirring rod to transfer a drop of the solution to a spotting tile. Add a drop of universal indicator.
4. Once it is neutralized (pH = 7 - green), pour the liquid into an evaporating dish and heat till it boils slowly.
Observations:
1. The acid was clear and watery.
2. When the base was added the mixture turned bubbly.
3. When the universal indicator was added, it continuously went red.
4. The mixture bubbled, and then small, white salt crystals formed.
Word equation for the reaction:
Hydrochloric Acid + Sodium Hydroxide ---> Sodium Chloride + Water.
Balanced symbol equation for the reaction: HCl + NaOH --> NaCl + H20.
