Lake Taupō and the Waikato River - an investigation

The inquiry focus was around water and we live in the perfect place to investigate it. We started by identifying what we already knew about water and what we wanted to find out.

We started by identifying what we already knew about water and what we wanted to find out.

Throughout, we revisited this chart and filled out what we had learnt.

Ecosystem Jars are a great way to capture the natural environment so that it can be studied in greater detail.

Four ecosystem jars to observe.

The samples were collected from 4 different sites around our local area

Onekeneke Stream
Taupō Lakefront
Onekeneke Stream
Taupō Lakefront
Waikato River - Reids Farm
Wharewaka Point
Waikato River - Reids Farm
Wharewaka Point

Students used water purity testing strips to test the water quality.

The pH levels between the different sites varied slightly between the sites, although all of our samples fell between the healthy pH range of 6.5 - 8.5.
The pH levels between the different sites varied slightly between the sites, although all of our samples fell between the healthy pH range of 6.5 - 8.5.

Our testing showed some variation in general hard water levels - particularly in the Waikato River site. Hard water testing shows the presence of minerals such as magnesium and calcium in the water. Typically, these minerals are present when water travels through rocks, sand and soil. So having a higher hard water result at the Waikato River site isn’t unexpected. This sample also took a few days to settle and clear.

We wrote a question to investigate - Is there animal life in our local waterways?

And we wrote a hypothesis that we would test using the samples.

My hypothesis is that there will be bugs in the lakefront sample but not in the Waikato River sample

 

My hypothesis is that there will be bugs in the Onekeneke and Wharewaka Point samples.

Students drew a scientific diagram to record their investigation.
Everyday the students made observations of the samples, seeing if they could see any living organisms.

I think I can see eggs on the algae.

We zoomed in on a Paleoceanographer from America to talk to her about her research into keeping waterways healthy.
She shared her experiences with us about revitalising polluted waterways.

Arley asked her what he could do as a child to help his local waterway clean. She had some great ideas that Arley could do including:

  • Pickling up rubbish,

  • Taking regular photos to monitor

  • Using test strips to monitor the water quality.

This water sample scientific investigation prompted more questions from the students about rivers and how they are formed.  This led itself to another science investigation. We crumpled paper up and ‘created’ our very own mountain ranges and coloured where we thought the water would run down.

Students wrote a hypothesis about our mountains and rivers experiment

The river is going to go down the folds of the paper.

The water will soak into our mountain and it will also drip down.

The water will run down the valleys.

Then the fun part! We sprayed our mountains with ‘rain’ and watched what happened.

We then watched what happened to the water as more was sprayed on.

When we sprayed water on our mountain range we observed that the water ran down the canyon because of the folds that were made. This made a lake. 

When we sprayed water on our mountain range we observed that the rain came down in little rivers. In different places some water stayed on top in the craters because it was a dip and in other areas it ran down the sides because it was a slope. Mt hypothesis was correct because I predicted that it would go in different directions.

When we sprayed water on our mountain range we observed lots of rivers connecting to lakes and oceans because of all of the valleys. Some water pooled up in a little crater.

Our investigations into our local waterways have focussed our student inquiries and we collated our information onto padlets.

My journey in education has taken me down many different paths including teaching in an Area school, urban English and Welsh schools, small semi-rural schools and in a purpose built Innovative Learning Environment.

Teaching at Wairakei Primary School allows me to use so many of the skills I gained in these different settings - as well as acquiring so many more. I consider myself a life-long learner and continuously strive to build on my knowledge of teaching and education in order to create the best possible outcomes for students.

In my spare time I enjoy playing netball, reading, getting out and about with my two children and making the most of what this area has to offer.
