Goal Setting 2021

 Kia ora! Once again for term 2, I've created another goal-setting document for term 2. Below, you can read about my subjects this year, my learning work-ons, and the ambitions I wish to have done by the end of this term.

I usually like to set a high standard for myself but in the past, sometimes when I would force myself to do too much I'd just end up putting pressure on myself and not getting anywhere. So, this term I've decided to do what I think will help me best. 

What are your goals and ambitions for this year?

Dilution and filtration

Hola! On Wednesday last week, my science class did an experiment! We used a chemical called Copper nitrate, we also used water. We diluted the solution 4 times. After that, we made a little cone out of filter paper, put it in a funnel and poured our solution in. Why did we do that? Over the next few days, crystals should've formed. 

Looking back today. there are small crystals along the side of the filter paper. I think that the experiment has worked. 

Questions - 1. Which test tube had the most concentrated sample of Copper nitrate?

The first test-tube had the most concentrated sample of copper nitrate.

2. When we added water what were we doing to the concentration of the solution?

We were diluting the solution 

3. Which concentration of copper nitrate formed the most precipitate, why do you think this is the case?

The last one, by the 4th test tube copper nitrate, had been diluted x1000. 

Solvent: The liquid

Solute: The solid you are trying to dissolve.

Filtrate: Separating the solute (solid) from the solvent (liquid).

Precipitate: When a solid forms in a liquid.

Water Boats

 Hello and welcome back to Term 2! First period I have Science and for our first task this term we used bunsen burners and made little containers out of paper and looked at how long our container would hold up against fire.

Aim: Designing a container out of paper that holds water and doesn't catch on fire.

Method: We first designed the container that we thought would hold water, second we set up all our equipment, turned on the gas and put our container on the tripod, lastly we turned off the gas when our container started to collapse or go up in flames.

6 things we used: Bunsen burner, beaker, A4 paper, water, heat mat, tripod

Results: My container withstood the fire for about 15 seconds.

Conclusion: Our containers base wasn't as strong as we would've liked it to be. It got through the paper in a short amount of time. Something I would do differently next time is create layers and make the base stronger. One tip I would give to someone doing an experiment is to make the air hole is closed (labelled in the diagram).
