State of quadrat now?
 It has got lots of rubbish and polluted

What can we change to make the quadrat better?
1) We will pick up rubbish because it’s polluted
2) We will water the ground because it’s very dry and not growing much

What should I measure in two weeks to see if there is a change?
The amount of rubbish in the soil and how it has grown plants or insects

Expert feedback from David Winter, zoology PhD student at Otago University:

A good idea but you have to think about making sure you're doing a fair test. How will you know your results were down to the changes you made and would have occurred anyway?

 

The Louise’s

Group Members:  Georgia, Sophie and Louise

What state is our quadrat in now?
At the moment, our quadrat has very dry soil. There are currently no worms living in our quadrat.

What can we change to make the quadrat better?
We  are going to remove the bad soil from half of our quadrat, and put in some nicer, healthier compost, produced by the year 7’s at school.

What should I measure in two weeks to see if there is a change?
We should measure how many worms there are living in our quadrat. Even one worm will be an improvement to its current state.

Expert feedback from David Winter, zoology PhD student at Otago University:

Nice! A good improvement plan, a fair test and a clear idea of what you'll measure. Good luck.

 

The Kings

Group Members: Katala, Chelsea, Cate, Hilary

What state is our quadrat in now?
-no worms
-dry
-crumbly

What can we change to make the quadrat better?
Add compost

What should I measure in two weeks to see if there is a change?
-the worm & bug population
-compost

Expert feedback from David Winter, zoology PhD student at Otago University:

Another good idea, but you have to make sure you are doing a fair test - your plan doesn't have a control to compare your compost results with.

What can we change to make the quadrat better?
Plant a white rata and water it every day in half of the quadrant so it may improve the soil as it was dry.

What should I measure in two weeks to see if there is a change?
How much the plant has grown and if it’s made a difference to the soil and see if the soils not as dry.

Expert feedback from David Winter, zoology PhD student at Otago University:

Sounds good, will the rata be in the middle of the quadrant or only on the watered side. How will choice that effect your experiment?

 

Able

Group Members: Brynee, Eilish,  Alisha and Liana

What state is our quadrat in now?
The dirt is very crumbly

What can we change to make the quadrat better?
Add water to one of the squares so that the dirt gets all moist
For another square add worms as there isn’t much bugs in our metre

What should I measure in two weeks to see if there is a change?
If the soil is still crumbly and if our changes have made a difference.

Expert feedback from David Winter, zoology PhD student at Otago University:

Cool, it's not quite clear from your report if you are leaving some of the squares in quadrant as a control which you'll need to do to make a fair test. How will you know if your change have made differences (will you count worms, measure something about the soil...)

 

Henry Ford

What state is our quadrat in now?
Moist because of rain, but still crumbly

What can we change to make the quadrat better?
Plant a Chilean Bellflower over half the quadrat.  We will water it once and leave it to grow.  We will leave the other side unchanged.

What should I measure in two weeks to see if there is a change?
Measure the plant to see if it’s grown and if there’s any difference

Expert feedback from David Winter, zoology PhD student at Otago University:

Good to see you've thought about how to make a fair test. How are going to measure the difference between the planted and unplanted side of your square?

 

Little Einsteins

Group members: Millie, Karorangi, Ruby, Tae-Ana

What state is our quadrat in now?
Dry and crumbly

What can we change to make the quadrat better?
We are going to put water on the soil because we think that since the soil is so dry it affects what lives there.  We think that if there is more water in the soil, it will get moisture so more bugs can live in it which means that we will have more success.  We are going to water it every science lesson for consistency.

What should I measure in two weeks to see if there is a change?

The amount of bugs.

Expert feedback from David Winter, zoology PhD student at Otago University:

Some nicely thought through hypotheses, well done. Now, think about how you can make it fair test - if you find more bugs after you water your square you want to know it was because of what you improvement and not just by chance!
